Remembering Alan J. Friedman

Ellen F. Mappen,
National Center for Science and Civic Engagement

I am honored but saddened to write a brief introduction to this section that includes remembrances from a number of Alan J. Friedman’s colleagues. Alan was the inspiration behind the National Center for Science and Civic Engagement’s SENCER-ISE initiative, a project to encourage cross-sector partnerships between informal science and higher education institutions, and was also its founding project director.

Wm. David Burns, in his introduction to this special issue of Science Education & Civic Engagement: An International Journal on informal science education, notes that he “saw Alan as a humanist and scientist.” Certainly the selections that follow from Alan’s colleagues bear witness to the multifaceted nature of his interests, experiences, ideas, and lasting contributions to the field of education, science, and literature and to the impact he had on the lives of the many colleagues who knew him. Alan’s interests were wide ranging and included not just a desire to communicate science to the general public, students, and teachers but also to examine cultural influences on science and technology.

In an interview published in these pages in the Summer 2011 issue, Alan described how he came to the field of informal science education. He was a solid-state physicist by training and in 1973 held a visiting professorship at the University of California, Berkeley. He mentioned how he had wandered into the Lawrence Hall of Science, one of the pioneering public science-technology centers. This experience changed his life and he ended up spending twelve years at that institution, primarily as the Director of Astronomy and Physics, with a short leave to serve as the Conseiller Scientifique et Muséologique at the Cité des Sciences et de l’Industrie in Paris from 1982–1984. In 1984, he became director of the New York Hall of Science, a position he held until he retired in 2006. At NYSCI, he revitalized the moribund institution. A description of what he found in 1984 (“zero attendance the year before he arrived”) compared with what NYSCI had become by 2006 when he retired can be found on the NYSCI website: 447,000 visitors with over 90 full-time staff and 150 high school and college students who served as Explainers in the Science Career Ladder program, one of Alan’s lasting initiatives. In his retirement years, Alan was a Museum Development and Science Communication Consultant and a cherished scholar at the National Center for Science and Civic Engagement.

To open this section, Sheila Grinell shares her memories of Alan’s last trip abroad, to Al Khobar, Saudi Arabia, and of her long working relationship with him. In relating her conversation with Alan that took place before their meetings started, she mentions his goal of using SENCER-ISE to bring together educators who have different “institutional perspectives” and also gives us a “Reader’s Digest” version of what they discussed. From Eric Siegel, we learn about how Alan always explored the “intersection of science with the arts and humanities” and wanted to understand “the impact of science on society,” and we learn much about Alan’s intellectual interests and pursuits that ranged well beyond directing a major science center. Alan Gould’s brief remembrance highlights how much he learned from Alan Friedman about planetarium presentations and how best to engage audiences in this exciting experience. Priya Mohabir focuses on Alan’s contribution to the education of high school and college students and his vision to empower them as science communicators while they themselves learned science. David Ucko’s “SENCER Synergies with Informal Learning” gives us an overview of how David Burns and I came to collaborate with Alan in our efforts to work across different educational sectors. David Ucko also provides us with an understanding of the differences between formal and informal learning and his thoughts about SENCER as “a model for synergistically integrating aspects” of these different modes of education. We end this section with a reissuing of “In Memoriam,” David Burns’ memorial tribute that he wrote on May 5, 2014, the day after Alan’s untimely death.

We have lost Alan Friedman and greatly miss his wisdom and friendship. But as Alphonse DeSena, our Program Director in the Division of Research and Learning at the National Science Foundation (NSF), wrote recently,

Over several decades of service to education and science, Alan Friedman’s ideas, actions, and accomplishments were many, insightful, and significant.   His contributions in varying capacities to NSF’s mission and programs were frequent, critical, and game changing.  We at NSF and in the informal science education field cherished him as a colleague, as (in my case) a mentor, and as a friend. His legacy will continue for years to come.

Brownfield Action: Dissemination of a SENCER Model Curriculum and the Creation of a Collaborative STEM Education Network

Abstract

Brownfield Action (BA) is a web-based environmental site assessment (ESA) simulation in which students form geotechnical consulting companies and work together to solve problems in environmental forensics. Developed at Barnard College with the Columbia Center for New Media Teaching and Learning, BA has been disseminated to 10 colleges, universities, and high schools, resulting in a collaborative network of educators. The experiences of current users are presented describing how they have incorporated the BA curriculum into their courses, as well as how BA affected teaching and learning. The experiences demonstrate that BA can be used in whole or in part, is applicable to a wide range of student capabilities and has been successfully adapted to a variety of learning goals, from introducing non-science-literate students to basic concepts of environmental science and civic issues of environmental contamination to providing advanced training in ESA and modeling groundwater contamination to future environmental professionals.

Introduction

Brownfield Action (BA) is a web-based, interactive, three-dimensional digital space and learning simulation in which students form geotechnical consulting companies and work collaboratively to explore and solve problems in environmental forensics. Created at Barnard College (BC) in conjunction with the Columbia Center for New Media Teaching and Learning, BA has been used for over ten years at BC for one semester of a two-semester Introduction to Environmental Science course that is taken each year by more than 100 female undergraduate non-science majors to satisfy their laboratory science requirement. BA was selected in 2003 as a “national model curriculum” by SENCER (Science Education for New Civic Engagements and Responsibilities), an NSF science, technology, engineering, and mathematics (STEM) education initiative. The BA curriculum replaces fragmented, abstract instruction with a constructivist interdisciplinary approach where students integrate knowledge, theory, and practical experience to solve a complex, multifaceted, and realistic semester-long interdisciplinary science problem. The overarching themes of this semester are civic engagement and toxins, focusing on toxification of the environment, pathways taken by environmental toxins, and the impact of toxins on the natural environment and on humans. Readings that have been used to complement teaching using BA include Jonathan Harr’s A Civil Action and Rachel Carson’s Silent Spring.

The pedagogical methods and design of the BA model are grounded in a substantial research literature focused on the design, use, and effectiveness of games and simulations in education. The successful use of the BA simulation at Barnard College is fully described in Bower et al. (2011). This article describes multiple formative assessment strategies that were employed using a modified model of Design Research (Bereiter 2002; Collins 1992; Edelson 2002), culminating in a qualitative ethnographic approach using monthly interviews to determine the impact of BA on the learning process. Results of these ethnographies showed at a high confidence level that the simulation allowed students to apply content knowledge from lecture in a lab setting and to effectively connect disparate topics with both lecture and lab components. Furthermore, it was shown that BA improved student retention and that students made linkages in their reports that would probably not have been made in a traditional teaching framework. It was also found that, in comparison with their predecessors before the program’s adoption, students attained markedly higher levels of precision, depth, sophistication, and authenticity in their analysis of the contamination problem, learning more content and in greater depth. This study also showed that BA supports the growth of each student’s relationship to environmental issues and promotes transfer into the students’ real-life decision-making and approach to careers, life goals, and science (Bower et al. 2011).

BA is one of a small but growing number of computer simulation-based teaching tools that have been developed to facilitate student learning through interaction and decision making in a virtual environment. In STEM fields, other examples include CLAIM (Bauchau et al. 1993) for mineral exploration; DRILLBIT (Johnson and Guth 1997) and MacOil (Burger 1989) for oil exploration; BEST SiteSim (Santi and Petrikovitsch 2001) for hazardous waste and geotechnical investigations; Virtual Volcano (Parham et al, 2009) to investigate volcanic eruptions and associated hazards; and eGEO (Slator et al. 2011) for environmental science education. These virtual simulations give students access to environments and experiences that are too dangerous, cost-prohibitive, or otherwise impractical to explore (Saini-Eidukat et al. 1998). Through directed role play they also provide opportunities for social interaction and student inquiry into the human element of technical analysis and decision making (e.g., Aide 2008).

What makes the Brownfield Action SENCER Model Curriculum unique among these STEM online simulations is that it includes a significant component of engagement with the civic dimensions of environmental contamination, interwoven with the technical investigations being conducted by the students. The BA simulation is also unique in that it has been disseminated to ten colleges, universities, and high schools, and a collaborative community of users has developed. To the best of our knowledge, BA is the only SENCER national model curriculum with a network of faculty collaborating in a community of practice. Moreover, this network has adapted the original simulation and its related products for use with a widening diversity of students, in a variety of classroom settings, and toward an expanding list of pedagogical goals. This paper documents the experiences of ten teachers and professors (in addition to those at Barnard College) who are using BA to improve student learning and teaching efficacy, to improve retention in the sciences, and to increase student motivation and civic engagement. All of these teachers and professors have shared their experiences, course materials, and curricula developed using the BA simulation in their courses, and the evolution of this collaborative network has now begun to define the direction that BA is taking. Currently the network consists of environmental scientists, an environmental engineer, a sociologist, geologist, GIS specialist, a smart growth and landscape architect, and high school science teachers, all sharing the goal of teaching science from the perspective of promoting civic engagement and building a sustainable society. Team members have developed course content specific to their individual fields of expertise and have made their course materials available to the community. The goals of this collaborative network also include telling the story of the dissemination of BA and thereby encouraging the dissemination of other successful SENCER model curricula. Ongoing efforts are being made to expand the BA network, especially among the hydrogeologic, brownfield, and environmental site assessment community. The BA SENCER Team has also begun to develop BA for use in online education.

The purpose of this paper is to present the collective experiences of the college and university faculty and high school teachers who have incorporated the BA simulation and curriculum into their courses. The experiences using BA reported here demonstrate how the BA simulation can be adapted for use, in whole or in part, for a wide range of student capabilities, and the authors describe how BA affected student learning and satisfaction. The descriptions that follow include applications of the BA simulation to environmental instruction at the high school level (Liddicoat, Miccio, Greenbaum), to the fundamentals of hydrology and environmental site assessments at an introductory to intermediate undergraduate level (Bennington, Graham), and to training both undergraduate and graduate students in advanced courses in hydrology and environmental remediation (Lemke, Lampoousis, Datta, Kney). Although many of the applications reported here apply to courses in STEM curricula, BA is not restricted in its utility to teaching students with advanced STEM skills. Rather, BA has proven to be equally effective whether it is used to introduce non-science-literate students to basic concepts of environmental science and basic civic issues of environmental contamination or to provide advanced training in environmental site assessments and to model groundwater contamination to future environmental professionals.

By contacting the lead author (Bower), one can obtain a username and password to access the simulation, see the library of documents, maps, and images related to the simulation and its use in the classroom, and visit the “User Homepages” where the authors from the collaborative network describe their use of BA in more detail than is done in this paper and provide additional documents and maps. These instructors have expanded the pedagogy of BA by utilizing the simulation in unique ways and in contributing new curriculum. In the “User Homepages,” new or potential users can find an instructor whose use of BA parallels their own, begin a dialogue, and become part of the collaborative network.

Teaching High School Students the Fundamentals of Environmental Science

Joseph Liddicoat, Barnard College

Using the interactive, web-based Brownfield Action simulation, a total of 48 public high school students from the five boroughs of New York City who were enrolled in the Harlem Education Activities Fund (HEAF) were taught environmental science in a way that combines scientific expertise, constructivist education philosophy, and multimedia during 12-week programs in the fall of 2009, 2010, and 2011 at Barnard College. In the BA simulation, the students formed geotechnical consulting companies, conducted environmental site assessment investigations, and worked collaboratively with Barnard faculty, staff, and student mentors to solve a problem in environmental forensics. The BA simulation contains interdisciplinary scientific and social information that is integrated within a digital learning environment in ways that encouraged the students to construct their knowledge as they learned by doing. As such, the approach improved the depth and coherence of students’ understanding of the course material.

In Barnard’s partnership with HEAF, BA was used in modular form to gather physical evidence and historical background on a suspected contamination event (i.e., leakage of gasoline from an underground storage tank) that resulted in the contamination of the aquifer in a fictitious municipality, Moraine Township. The HEAF students assumed the role of environmental consulting firms with a fixed budget to accumulate evidence about a parcel of land intended for a commercial shopping mall and to report the feasibility of using the property for that purpose. Through the integration of maps, documents, videos, and an extensive network of scientific data, the students in teams of three and working with a Barnard undergraduate mentor engaged with a virtual town of residents, business owners, and local government officials as well as a suite of geophysical testing tools in the simulation. Like real-world environmental consultants, students had to develop and apply expertise from a wide range of fields, including environmental science and engineering as well as journalism, medicine, public health, law, civics, economics, and business management. The overall objective was for the students to gain an unprecedented appreciation of the complexity, ambiguity, and risk involved in investigating and remediating environmental problems.

The Barnard undergraduate mentors were familiar with BA from doing the simulation as part of an introductory science course. The mentoring included weekly assistance with writing and mathematical exercises, and guidance in writing a Phase I Environmental Site Assessment report that was required of each HEAF student. Assessment of the program included weekly journals reviewed by one of us (RK) at Columbia University’s Center for New Media Teaching and Learning. The student mentors also provided information throughout the program on the progress of the students and their role in the program.

Overall, the students responded well to computer-based learning, especially the students who perceived themselves to be visual learners. Videos were especially effective in the instruction, as were hands-on laboratory activities (e.g., sieving of sand, permeability measurement exercise, measuring movement of a fictitious underground plume in a water model) as evidenced by open-ended journal responses from the students. One additional activity mentioned by nearly every participating student was the weekend retreat to Black Rock Forest, a 3,830-acre second-growth forest near West Point, NY, which Barnard helps to support. This retreat provided the HEAF students an opportunity to interact informally with each other and the HEAF staff, their mentors, and the Barnard instructors. Those two days allowed immersion in topics about geology, biology, botany, and ecology that the students did not encounter in the urban environment they lived in. As the 12-week program progressed, students frequently expressed their concern about gas stations in their neighborhood, which is a potential form of brownfield known to all of them. An indication of sustained interest in the program was the high percentage of student attendance, considering the students’ sometimes difficult commute on public transportation from the five boroughs to Barnard within an hour of when they were dismissed from their high school. Average weekly attendance was 91% in year one, 98% in year two, and 92% in year three. Recommendations made by student mentors based on their experiences with the program include the suggestion that the mentors be utilized more fully in the instructional process to allow them to provide more context and other scaffolding support during group work time. This would allow for less large group lecturing and more peer instruction, as participants reported benefitting more from structured group time with mentor guidance than from the full group lecture components of the curriculum.

Briane Sorice Miccio, Professional Children’s School

Brownfield Action has been used for four years in a high school Environmental Science class consisting of students in grades 10, 11, and 12. The class met 40 minutes each day, five days a week for seven weeks. During this time, the students investigated the gasoline plume emanating from the BTEX gas station and then wrote a Phase II ESA.

BA has been an invaluable tool in demonstrating many of the concepts covered in the curriculum. It has given the students a “hands-on” opportunity to put into practice the topics and skills they have learned. They were able to study a number of concepts, including groundwater movement (porosity, permeability, D’Arcy’s Law), topography and contour mapping, and the chemical and physical properties of gasoline, while simultaneously experiencing how the knowledge of these concepts can be applied in a real-world situation. There was also an in-class demonstration of the movement of a contamination plume through a cross section of an aquifer, as well as a sediment size analysis using sieves to separate a sediment sample “taken” from the ground near the BTEX gas station. Students were able to physically see the different components of sediment and relate the different sized particles to the speed with which groundwater, and any inclusive contamination, is able to flow. With BA, students are able to learn, apply their knowledge in an ongoing interdisciplinary exercise, and see how all of these separate concepts taught in environmental science class tie together in the real world.

The Environmental Science course has been taught for seven years with BA being used for the past four years. BA made a tremendous difference, satisfying both the goals of the curriculum as well as enhancing student interest. Students are given the opportunity to investigate the environmental, social, and economic issues facing a community that is forced to deal with a brownfield and contamination of the local environment. New York City has over 40,000 brownfield sites, many of which are unknown to its residents. When students who live in the city work with BA, whose narrative deals with the ramifications of contamination in a small town, they are able to gain a better understanding of the magnified ramifications in a larger city. This, in turn, will make them socially aware of the effects of a brownfield on the people surrounding it.

Typically, students execute the “learn and apply process,” where they learn in class and apply these concepts to a one-time lab exercise and exam before moving on to the next topic. However, with BA, the students are enthusiastic about applying what they have learned in a more interesting, realistic, and interactive format. Since the implementation of BA, students have been more receptive, and it has sparked more questions and comments than ever before. The students’ questions have also demonstrated a deeper understanding of the subject matter than with traditional textbook work. The students are also able to incorporate problem-solving skills, exercise leadership skills and management strategies, and work collaboratively. Moreover, they are able to recognize the social and economic ramifications of pollution. In addition, BA’s demonstration of the work of an environmental site investigator has, on more than one occasion, inspired students of mine to pursue the field of environmental science in college. Since my students are all college bound, the fact that Brownfield Action inspires interest in this field, particularly now when we need the next generation to be environmentally conscious, is gratifying and demonstrates the value of Brownfield Action within a high school curriculum.

Bess Greenbaum, Columbia Grammar and Preparatory School

Columbia Grammar & Prep is a private K-12 school in Manhattan, NY. The Brownfield Action simulation was utilized in two sections of the yearlong environmental science elective course, open to juniors and seniors. (One section had nine students; the other had 14. All of the 23 students were in either 11th or 12th grade, except for one in 10th grade). The high school students investigated the gasoline plume and associated drinking water well contamination portion of BA simulation. The goal of the project was to engage the students in some real methodologies used to detect and delineate contaminant plumes.

Students completed the investigation in teams of two or three over seven weeks. Groups were chosen by the instructor, who had, at this point, a fairly good sense of each student’s ability and motivation level. In order to avoid the common pitfall of one student in the group doing all the work, students were grouped according to similar ability and motivation levels. This was a successful tactic. First, students were introduced to the concepts of brownfields and superfund sites. Then, they were shown how to log onto and navigate the BA computer simulation and the features for each new test. The students found the online interface to be very user-friendly.

Each team conducted tests and made maps of the gasoline plume, but each student was responsible for submitting their own final four- to six-page report along with four hard-copy maps. One map was a basic site map, and three were topographic maps of the site highlighting different data: surface topography, bedrock topography, and water table elevations. Students utilized two tests for contamination provided in the simulation: soil gas sampling and analysis and drill/push testing. Prior to conducting these tests, the instructor spent two or three class periods discussing with the students the major components and characteristics of gasoline. Students discovered that gasoline is a mixture of many substances, each with its own physical and chemical properties. We discussed that gasoline contained floating, volatile, and water soluble parts. For this investigation, we focused on two tests for the presence of gasoline provided in the simulation. First, the Soil Gas Sampling and Analysis (SGSA) tested for hexane, a volatile component found in the air pockets of the soil. The second test detected the presence or absence of benzene, a water-soluble component. Once the presence of hexane in the soil was confirmed, students used the Drilling and Direct Push test to see if there was any benzene in the groundwater. Students learned that the tests were performed in this order because it was financially practical; if gasoline had not been present in the soil, it would have likely been wasteful to perform the more expensive and time-consuming test on the groundwater. The final report submitted by each student had three main parts: (1) a summary letter to the EPA outlining reasons for, and results of, their investigation; (2) a description of investigation methods, testing procedures, and data; and (3) analysis and interpretation of the data.

Students varied widely in their spatial visualization abilities. Some were quite challenged by creating and understanding the meaning of the hand-drawn topographic maps. While tedious, this tactile and methodical process improved student understanding of mapping; however, comprehending the meaning of the aerial view of the plot of the hexane data (from soil gas measurements) and the cross-sectional view of the benzene data in the groundwater contaminant plume was not so obvious for some. The concept that each contamination map represented a different orientation (either cross-section or aerial view) of the contaminant plume was repeatedly emphasized. Students understood why there was a need to test for a volatile compound (hexane) in the soil and a soluble one (benzene) in the water table, but their understanding of sediment properties and the movement of groundwater was simplistic.

The BA simulation was a good classroom experience. Based on observations, students enjoyed the self-paced group work. Two adjustments for future use are suggested. First, introduce exercises in spatial orientation earlier on in the year. This would help students grasp the concept of topographic maps more easily, and they would be better equipped to identify and draw contour lines based on elevation points. Second, the experience could be enhanced with hands-on demonstrations of sediment size class and porosity/permeability of different sediments. These adjustments would likely allow students to take a more independent role in the investigation, and require less instructor guidance as they investigate the task at hand.

Although students were given a budget, the focus was on completing the Phase II investigation—regardless of cost. Some students were initially mindful of how much each test cost, but once they knew that it did not really matter how much they spent, they no longer paid attention to this feature of the simulation. Students did, however, take advantage of the Moraine township history and interviews with the citizens in order to make their final assessment and report. Another tactic that might improve student autonomy and the BA experience would be to have them work together to figure out the most logical order of steps to take in the investigation process. A class discussion of crime shows or A Civil Action would facilitate this. Once they reach consensus on a logical way to carry out the investigation, they could be introduced to the simulation’s tools.

Teaching Environmental Science Students Fundamentals of Hydrology and Environmental Site Assessment

Bret Bennington, Hofstra University

Brownfield Action (BA) is used throughout the entire semester in both an undergraduate hydrology course (Hydrology 121) and a graduate hydrogeology course (Hydrogeology 674). These are combined lecture/laboratory courses taken by students pursuing degrees in geology, environmental science, or sustainability studies, most of whom are motived by an interest in applying science to solving environmental problems but who have little prior experience in groundwater science. Students are assigned to groups of three or four to form consulting teams. Teams are provided class time each week during laboratory to meet and coordinate online work performed individually outside of class hours. Students use the simulation to conduct a Phase I ESA (Environmental Site Assessment), and each group is required to make a presentation to the rest of the class detailing their findings and to submit a Phase I ESA report midway through the term. During the second half of the semester the teams work on a Phase II investigation. Final group presentations communicating the results of the Phase II investigation are made at the end of the term, and each student is required to submit an individual Phase II ESA report for evaluation. Students use critical feedback from the assessment of the Phase I materials to improve their Phase II presentation and reports.

A useful attribute of the BA simulation is that important hydrologic concepts introduced in lectures and labs can be incorporated into different stages of the online BA investigation, providing students the opportunity to practice applying these concepts in realistic, problem-solving activities. For example, in one laboratory exercise, students measure the porosity and hydraulic conductivity of a sediment sample obtained (hypothetically) from the abandoned Self-Lume factory site in the BA simulation. In another exercise, students learn how to calculate the direction and magnitude of a hydraulic gradient from hydraulic head data collected from monitoring wells. As part of their Phase I and Phase II investigations, students use these sedimentological measurements and groundwater analytical methods, in combination with data obtained in the online simulation, to calculate flow volume and seepage velocity beneath the Self-Lume site to assess potential impacts to the town water supply well. Students must also incorporate into their investigations knowledge of groundwater law and the regulations and standards governing environmental investigations, methods of aquifer testing and analysis, and the behavior of different forms of groundwater contaminants. To complete their ESA investigations within the BA simulation, students are thus required to integrate a wide range of data, methods, and concepts learned across the course.

Navigating the BA simulation also introduces students to the different components of civil government and the variety of agencies and departments involved in regulating and maintaining public health and groundwater quality. Students are drawn into the simulation by the authenticity of the online world provided, which is supported by realistic, richly detailed documents, newspaper articles, videos, and video and text interviews with public officials. It is a revelation to most students that so much useful information on potential environmental problems can be obtained just from interviews and municipal documents. In addition, the BA simulation provides many opportunities for students to develop critical thinking and problem-solving skills, as well as professional and technical skills, most importantly the ability to interpret, summarize, and effectively communicate technical information. As part of their course requirements, students must produce two formal, professionally written and formatted technical reports, and one informal and one formal oral presentation, and they must draft topographic, water table, and bedrock contour maps, as well as maps summarizing data from different aquifer tests and analyses. Finally, students gain valuable experience working cooperatively as part of a team focused on solving problems on time and within a reasonable budget. (Student teams are billed for all activities within the simulation and are assessed on how cost-effective their investigations are.)

Figure 3. Average student responses to questions asking them to rate the effectiveness of the Brownfield Action simulation for aiding student learning. Responses ranged from 1 (most negative) to 10 (most positive). Error bars indicate average +/- one standard deviation.

In the past year and a half students were surveyed to determine their perceptions of the effectiveness of BA as a teaching tool. Student response to the BA simulation has been overwhelmingly positive, with a large majority of students indicating that BA was successful in facilitating student learning and providing experience with data analysis, interpretation, and problem solving (see Figure 3). More recently, in the fall of 2013, a SENCER Student Assessment of Learning Gains (SALG) instrument was deployed in the Hydrology 121 course at Hofstra University (nineteen undergraduate geology and environmental resources majors) to assess student gains in understanding and skills derived from their experiences with the semester environmental site assessment project built around the Brownfield Action simulation. Results from this assessment indicate moderate to large gains in understanding of course content (Figure 4) and relevant cognitive skills (Figure 5) learned and practiced while working with the BA simulation.

Figure 4: Changes from the beginning to the end of the semester in the mean d Mean) and standard deviation (d Std dev)value of responses to questions asking students to rate their understanding of environmental and hydrologic concepts learned in the course working with the Brownfield Action simulation. An increase in the mean of the responses indicates a gain in understanding relative to a 5 point scale. A decrease in the standard deviation value indicates greater agreement among student responses.

Many students report that BA increased their interest in pursuing hydrogeology and environmental consulting as a career (although some have also indicated that they learned from using BA that this was not the career path for them). Students have also reported that knowledge and experience of how to conduct Phase I and Phase II ESA investigations obtained through the BA simulation have been a very positive factor in interviews for jobs in environmental consulting. As one student wrote, “The Brownfield Action simulation not only helped me define a career goal, but it also helped me land a job in the environmental field. The skills and knowledge I gained through the simulation not only made my résumé look stronger to future employers but it allowed me to impress interviewers through conversation. Many potential employers were impressed by the fact that I knew enough about federal regulations and environmental concepts to even just carry on a discussion about Environmental Site Assessments.”

Figure 5. Changes from the beginning to the end of the semester in the man (d Mean) and standard deviation (d Std dev) value of responses to questions asking students to rate their ability to apply academic skills learned or practiced in the course working with the Brownfield Action simulation. An increase in the mean of the responses indicates a gain in ability relative to a 5 point scale. A decrease in the standard deviation value indicates greater agreement among student responses.

The BA simulation has proven to be an effective teaching tool for three main reasons. It recreates the ambiguity of real-world problem solving by providing students with an open-ended set of environmental problems, and it requires that they apply what they have learned in the classroom without ever being told exactly what to do. It provides a richly detailed and realistic virtual world that students find interesting and that engages their curiosity by presenting them with realistic environmental problems to solve. Finally, the BA simulation provides a framework for demonstrating key concepts developed in hydrology/hydrogeology courses. Because much of the lecture instruction in these courses involves the mathematical analysis of groundwater flow, the students benefit from being able to apply concepts such as hydraulic conductivity, hydraulic gradient, hydraulic head, and seepage velocity to solve applied problems within the framework of the BA simulation. This helps the students to better understand these concepts, and it greatly increases their interest and engagement in hydrogeology. Students routinely comment on how much they enjoy working in the simulation and it has inspired a number of students to pursue careers in environmental consulting and groundwater remediation.

Tamara Graham, Haywood Community College

Haywood Community College serves a predominantly rural community in the Appalachian Mountains roughly one-half hour west of Asheville, North Carolina. Haywood’s Low Impact Development (LID) Program was launched in 2009 to provide workforce training and resources to foster more sustainable development in the region. Though the LID Program is relatively new, it is part of the College’s highly regarded Natural Resources Management Department, which has offered two-year associate degrees and professional certificates in Forestry, Horticulture, and Fish and Wildlife for more than 40 years. The LID Program complements these established programs by offering students the opportunity to study innovative strategies for mitigating the impact of development on natural systems, particularly the hydrologic cycle.

LID 230, The Remediation of Impacted Sites, is a required course in the LID Program that surveys issues related to environmental contamination from the Industrial Revolution in the nineteenth century to contemporary 21st-century brownfields remediation programs:

This course is designed to familiarize students with various scale remediation projects to enhance understanding of the role environmental repair has in sustainable development. Emphasis will be placed on case studies that cover soil and water remediation efforts necessitated by residential, commercial, industrial, governmental, and agricultural activity. Upon completion, students will be able to discuss and utilize the tools and technologies used in a variety of soil and water remediation projects. (Course description fromHCC Catalog & Handbook )

From the perspective of LID, the remediation of brownfield sites offers communities perhaps the greatest return on investment in terms of sustainability. Brownfields are among the most contaminated sites environmentally, and their remediation spurs reinvestment in otherwise dilapidated urban areas, creating walkable, vibrant spaces for living and working where infrastructure already exists, rather than necessitating further encroachment of development on rural land or “greenfields.”

In addition to a Brownfield Action (BA) training seminar held at Barnard College, the BA website contains a User Section with curriculum resources that have been have been an invaluable, engaging resource for developing Haywood’s LID 230 course. In the spring semester of 2011 and 2012, BA resources were first introduced at approximately week five of the sixteen-week semester course, with a close reading of A Civil Action. The shared curricula and resources, such as reading guides made available in the BA User Section, provided students with compelling historical background on the origins of current brownfields programs. Building on this foundation, in the final third of the semester students worked in small teams with the simulation to develop a Phase I ESA Report and supporting topographic and inventory maps. The BA video interviews, narrative, and interactive simulation piqued student interest and facilitated understanding of the complex, interdisciplinary, even labyrinthine nature of environmental remediation. Site exploration afforded by the simulation allowed LID students to work at their own pace to cultivate attention to detail (careful detective work) while simultaneously being mindful of the bigger picture. Coupled with students’ study of case studies of local remediation projects, the simulation effectively conveyed the complex and interrelated political, environmental, economic, and social factors at issue in environmentally contaminated sites and the necessity of collaboration among diverse entities to facilitate remediation and reuse.

Rather than appearing trite in the face of the somber topic, the playful nature of the simulation, with myriad puns and entertaining diversions woven through the narrative, helped to engage students and demystify the otherwise intimidating content. The fear of the effects of environmental contamination and intimidation regarding the process are perhaps the largest factors hindering collaborative public and private action to remediate sites. The BA simulation effectively addresses these barriers through its appealing, approachable format, effectively fostering collaboration among students to address complex problems and work toward solutions.

The BA simulation has provided an engaging learning opportunity for HCC’s students. Several LID graduates have obtained employment with local and regional planning agencies, where their experience with the BA simulation has proven invaluable in addressing complex brownfields projects in their respective communities. HCC appreciates the opportunity to integrate this innovative simulation into our curriculum and is eager to assist Barnard College in expanding its access as an educational resource to further sustainable development goals in the region.

Douglas M. Thompson, Connecticut College

The Brownfield Action (BA) simulation has provided an important component of the course Environmental Studies/Geophysics 210: Hydrology at Connecticut College since the fall of 2004. Attendance at a Brownfield Action seminar the previous year showed that the simulation was an ideal means to replace a paper-based simulation used previously. As an experienced user of BA, I can confirm that it is a wonderful learning tool that has brought a very realistic group activity to my classroom. The program also does a very good job helping students develop the scientific background and confidence needed to find employment in the groundwater consulting industry. More importantly, students enjoy the BA module and learn a great deal about basic project management and group collaboration skills that apply to a range of disciplines.

My first job after college was as a Project Geologist for a groundwater consulting company in New England. It was a good first job, but my undergraduate geology major and hydrology course had not prepared me for the types of decisions faced on the job. Years later as an instructor of a hydrology course, it was important that I share my consulting experiences in order to help prepare undergraduates for what can be a very good job opportunity after graduation. The BA simulation provides an excellent replication of many of the components of a Phase I site investigation. Several former students who now work in the groundwater consulting industry have said that they greatly appreciated the background they developed using the simulation.

Figure 6. The Brownfield Action “playing field” in the reconnaissance mode visiting the BTEX gas station.

In my class, students are divided into groups of two or three and are asked to investigate the contamination at the BTEX gasoline station. The students are required to determine whether contamination exists and to delineate the nature, extent, and source of contamination. Students are encouraged to use the soil gas sampling and analysis tool and to determine a rough map of where volatile organic compound concentrations are highest. The students are then required to install at least three shallow wells and one deep well to document the approximate source of the contamination and direction of flow in both the horizontal and vertical directions. Drilling location and well placement are important decisions for a successful project, and students often display a great deal of trepidation when they begin to install monitoring wells. The cost of a poorly placed well is an important reason for this. As someone who has stressed over drilling holes for real monitoring wells, I know that the angst that students display is a good indication that BA realistically simulates the decision-making atmosphere. The students then use the survey instruments, sample analysis options, and the resulting data to produce maps of the BTEX gasoline contamination plume and the free-product plume. Students complete a group report that presents their findings.

To supplement the basic materials supplied with the computer simulation, the program is augmented with additional data sources and activities. Existing documents as well as newly created documents are placed as a reserve in our library to replicate the task of going to government buildings to search municipal and state records. Each group is provided with a small sample of loess and asked to classify the soil based on a textural method. Students are taken on a field trip to the campus power station to see two large underground storage tanks. A mock site visit is also made there to identify potential sources of contamination and locations where monitoring wells might be installed. The BA simulation is also used as a means to demonstrate the basic principles of Darcy’s Flow and hydraulic conductivity learned in the class. The students are asked to complete an estimate of the rate of groundwater movement based on some simulated pump test data created for this purpose and the groundwater table slope they determine from their BA wells.

BA provides an excellent opportunity for students to understand how the site assessment process is approached. The simulation adds a sense of realism to the sometimes abstract topics learned. BA has become a very important component of Environmental Studies/Geophysics 210: Hydrology, and the program will be used as long as its software is viable.

Training Undergraduate and Graduate Students in Advanced Courses in Hydrology and Environmental Remediation

Larry Lemke, Wayne State University

Brownfield Action was originally incorporated into GEL 5000—Geological Site Assessment—at Wayne State University during the Winter-2010 semester as part of an NSF CAREER grant that focused on groundwater contamination in previously glaciated urban areas. BA continues to play an integral role in this course, which is offered to both graduate students and upper division undergraduates and typically attracts 20 to 24 students each time it is offered. BA forms the basis for a term project in much the same way that it is employed at Barnard College: teams of students at Wayne State use the BA simulation as the basis for formulating Phase I and Phase II Environmental Site Assessments and reports.

In the first phase, students strictly follow ASTM Standard E 1527-13 (formerly E 1527-05). After completing site reconnaissance, records review, and interviews (no sampling is allowed except for Topographic Surveys), students document their findings, opinions, and conclusions following the ASTM specified report format. In the second phase, students choose two Recognized Environmental Conditions (RECs) to be investigated following ASTM Standard E 1903-11. The 2011 revision of this standard prescribes application of the scientific method to evaluate RECs. To begin this process, students must schedule an interview with their client (the course instructors) to recommend Objectives, Questions to be answered, Hypotheses to be tested,Areas to be investigated, a Conceptual Modelfor contaminant migration including target analytics, a proposed Sampling Plan, and an estimated Budget. During the interview, one course instructor plays the role of a naïve business manager focused on liability and budget issues, while the second course instructor plays the role of an environmental manager who asks probing technical questions. After receiving client authorization, student teams proceed to implement their sampling plan and complete the Phase II ESA. In our experience, the role play exercise adds another realistic dimension to the BA simulation by providing students practice in communicating technical information and recommendations to clients in an oral format (in addition to writing professional reports).

Most recently, Gianluca Sperone, a co-instructor in the WSU course, developed an effective innovation by utilizing ESRI ArcGIS tools to perform the Phase I ESA analysis. After converting available materials from the BA simulation into ArcGIS Geodatabase format, he mapped the information accessible to student investigators during the Phase I site visit and interview process. Subsequently, he used the ArcGIS Spatial Analyst Extension to model potential subsurface contaminant migration in the event of a release into the BA simulation environment. In this way, Sperone was able identify potential areas for Phase II ESA recommendations and demonstrate the utility of GIS tools to perform analyses and prepare professional materials for communicating project results.

Feedback from our students has indicated that the authentic, realistic nature of the BA simulation greatly enhanced their ability to understand and apply the relevant ASTM standards. One student wrote: “I thought the BA simulation was invaluable to students. The Phase I ESA knowledge gained from reading through the standard is reinforced with the game. It puts a practical twist on a document that can be difficult to focus on (hooray for legal jargon!). The experience will greatly aid students heading into consulting/government jobs.”

Angelo Lampousis, City University of New York

The Brownfield Action simulation and curriculum has been used at two different colleges of the City University of New York (CUNY). In both cases BA was adopted at the undergraduate and graduate levels of the course “Phase II Environmental Site Assessments” (City College of New York EAS 31402 [undergraduate] and EAS B9235 [graduate], Hunter College GEOG 383 [undergraduate] and GEOG 705 [graduate]). The combined number of students introduced to the BA simulation to date is 24. The academic background of the students involved ranged from geology, environmental sciences, and geography, to urban planning and sustainability.

The BA simulation was used as a refresher for the Phase I process, since most students had already completed the Phase I environmental site assessment course that is also a prerequisite for the Phase II course. The BA simulation served this purpose exceptionally well. Students had the opportunity to experience and practice a realistic interview component of writing Phase I reports as they interacted with the characters of the simulation. This addressed a specific gap in the CUNY curriculum that, while strong in using real data on real estate properties located in New York City (Lampousis 2012), treated interviews as a data gap (i.e., per ASTM designation E1527 – 05) due to legal and other restrictions on allowing college students to interact with property owners in an unsupervised manner. The BA simulation addresses this gap through its incorporation of a wide range of very thoughtful fictional interviews. The BA simulation experience for CUNY students was realized through several homework assignments culminating in a Phase I report. Due to time constraints, considerable amounts of information from the simulation, including data for topography, depth to bedrock, and depth to water table, were made available to CUNY students from the very beginning. Students were also assisted by the instructor in their construction of a conceptual site model.

Overall, the adoption of the BA simulation within the two CUNY colleges greatly reinforced student learning on the topic of environmental site assessments. The BA simulation provided an opportunity to test the knowledge and level of students’ understanding achieved up to that point. Students were able to get a panoramic view of the process, from signing the initial contract to submitting a final report. Because everything they did in the simulation cost them money, they also experienced working within a budget. The BA simulation will be used in the future starting in the Phase I course offered in the fall, and there are plans to adapt the BA simulation for a geographic information systems platform in the “Introduction to GIS” scheduled for the spring semester 2014. The latter will be in collaboration with Gianluca Sperone of Wayne State University.

Saugata Datta, Kansas State University

Brownfield Action has been used at Kansas State University (KSU) since 2009 for the undergraduate and graduate students in the lecture and laboratory courses of Hydrogeology (GEOL 611, with an average of 20 students mainly from the geology, biology, agricultural and civil engineering departments), Introduction to Geochemistry (GEOL 605/705, 10 students, mainly from the geology, agronomy, and chemistry departments), and Water Resources Geochemistry (GEOL 711, eight students from veterinary medicine, geology, and agronomy). All three have been offered as interdisciplinary courses.

Figure 7. The Brownfield Action “playing field” in Testing Mode with zoom function applied and magnetometry/metal detection measurements being made.

In Hydrogeology, BA is utilized as the foundation for a one-month practicum. Students work in teams of three and are given complete access to the BA simulation and website including all data and documents. Student teams must choose a topic or specific problem to be solved within the BA simulation. Topics range from using the BA simulation and database for a Phase I ESA of the Self-Lume property or the BTEX Gas Station, for flow net exercises to delineate various contaminant plumes (gasoline or tritium), for simple permeameter measurements to understand hydraulic conductivity, or for utilizing the many soil exploration tools (drilling, seismic reflection and refraction, ground penetrating radar, soil gas) to determine plume location and its migration paths, and chemical characteristics of different contaminants. Lectures are developed based on the topics chosen. Each team is required to write a report on their findings and evaluate what they have learned from their practical experience with the simulation. Poster sessions have often been assigned so that students may share their experiences using the BA simulation with other students to demonstrate how different methods and principles are used to solve complex hydrological problems. Additional faculty members are invited to these poster presentations and interact with and question the student teams.

In Geochemistry, BA is used for one month as a case study as part of the final project. Students use BA in order to understand the chemical characteristics of organic contaminants, the chemistry of groundwater, and the use of various field or laboratory geochemical analytical tools to measure various contaminants, map these contaminants in the surficial soil cover, and create hydrochemical maps with piper diagrams for various inorganic contaminants. Students learn how different plumes will mix or impact each other. BA allows students to develop a clear understanding of the composition of different contaminants and their MCLs in the environment.

In Water Resources Geochemistry, BA has been used in collaboration with other users of BA from Lafayette College (LC) and Wayne State University (WSU). Students are assigned to investigate BA in order to write Phase I and II ESA reports. There are invited lectures from within KSU as well as video lectures transmitted by instructors from LC and WSU. Students from KSU present their findings to students in an Environmental Engineering course at LC and a geology course at WSU, who in turn present their findings to the KSU students. Working with instructors from WSU, students at KSU learn how to use ARC GIS on the BA database. The topics in this video conferenced course evolved from the joint use of MODFLOW and Groundwater Modeling Systems (EMS-i) in tracing groundwater contaminants in the BA aquifer.

Typical student comments about the use of BA include: “One of the greatest ways to connect to a real world problem and it was interesting how we were acting as consultants, and tried not to leak ideas to the other groups,” and, “I learnt more about the application of Darcy’s law when I was taught with BA, even the water table characteristics, and the direction of groundwater flow were more clear when BA was demonstrated to us.” Students also commented on how they learned to work as a consultant and that one cannot make mistakes that might result in losing the contract or not making a profit. Several students have gone to job interviews and used BA to demonstrate their knowledge of ESAs and to respond to questions from the interviewers. BA played a significant role in the hiring of these students by government agencies and has also led to a dialogue with these agencies on how to use BA within communities they serve that are affected by brownfields.

Arthur D. Kney, Lafayette College

Over the last seven years the Civil and Environmental Engineering (CE) program at Lafayette College has used Brownfield Action successfully in two courses: Environmental Engineering and Science (CE 321) and Environmental Site Assessment (CE 422). CE 321 is an introductory course, and BA is used to introduce the issues of brownfields, remediation, and environmental regulations. CE 422 is a course in which students learn how to do Phase I Environmental Site Assessments (ESAs) consistent with ASTM 1527. Because most of the fundamental science needed to understand and participate in the BA scenario is taught to CE students throughout their first few years of our CE program, use of BA in CE 321 and 422 is targeted at applying their accumulated fundamental skills and knowledge in a realistic simulation in addition to teaching the details of the ESA process. Following a two-week exercise utilizing BA, students are prepared to do a real-time site assessment on neighboring properties.

My experience has shown that BA is very applicable to the field of civil engineering from initial investigation through remediation and that the interdisciplinary, realistic nature of BA provides an effective tool with which to teach aspiring civil and environmental engineers. Connections to the practice of civil engineering are played out in numerous scenarios in BA. For example, understanding how chemicals move through the water and soil is made evident through models that civil engineers are taught in water quality and water resource classes. Methods and practices used in remediation are common themes taught in upper level environmental engineering courses. Additionally, ESAs must be accomplished by an “Environmental Professional” as outlined in the US CFR 40:312.21. BA provides a wonderful storyline linked to believable data that ties together individuals and their community with industry and very real economic and environmental concerns. In order to piece together the truth, critical thinking skills must be used to interpret and communicate the significance of data obtained from the simulation.

In CE 422 especially, the incorporation of BA has tremendously improved student understanding of the ESA process as compared to classes taught prior to use of BA. Anecdotal evidence from student conversations, faculty observations, student test scores, and the fact that BA continues to be a central part of CE 422 all support this statement. Beyond CE 321 and 422, students have reported that BA has strengthened their ESA skills in senior-level design projects and has provided evidence of competence when applying for jobs. In fact, it is not uncommon to hear that students have not only gotten jobs because of their ESA skills but have also gone on to perform ESAs in their jobs. Because of these reports from students, future plans include introducing some form of an ESA course for engineering professionals. Incorporating BA would be integral, because of the fact that one can quickly comprehend the overall ESA process through the interactive, informative framework of the simulation.

As part of the collaborative network, Saugata Datta from Kansas State University (see above) and I have used BA to complement several courses. Our most recent course development is a team-taught course module between Kansas State and Lafayette. Graduate and undergraduates from both institutions have worked together reconstructing plume flow via groundwater models like MODFLOW and Groundwater Modeling System (EMS-i), using data from the BA simulation. Students connect the groundwater solution to the models in the existing BA simulation and make the BA narrative come alive as they learn how the various chemical and kinetics principles of contaminants behave throughout the BA storyline. In addition, other collaborative engagements have blossomed through BA team interactions, such as a recent set of academic video discussions between Wayne State University, Kansas State University, and Lafayette College students and faculty revolving around the overuse of key nutrients, phosphorous and nitrogen. Consistent with professional practice, future plans include developing a workshop open to environmental professionals interested in learning how to conduct ESAs. BA would be used to help professionals connect to the task at hand just as it has been used in CE 422.

Discussion

Assessing the Effectiveness of the Brownfield Action Simulation

All faculty using BA in their courses report high levels of student engagement with the simulation and increased confidence in students’ ability to understand and apply science to solve problems. Although a simulation, BA is grounded in civil, legal, and scientific reality such that experience gained through BA is directly applicable to the real world. This is demonstrated by the many students who report that BA has assisted them in gaining employment as environmental professionals. Other important professional and conceptual skills reported being taught and learned in the context of the BA simulation include data visualization, map-making, budgeting, formal report writing, making formal oral presentations, as well as decision-making, dealing with ambiguity, teamwork, and networking in information gathering.

Reliable summative assessment of the pedagogical effectiveness of the BA simulation has not yet been performed due to the lack of appropriate control groups (the courses discussed above are not taught in multiple sections with some instructors using BA and some not) and a lack of appropriate data on student performance prior to the adoption of BA in courses. However, a variety of formative assessments of the BA simulation were incorporated throughout the design and initial use of BA at Barnard College to provide feedback and confirmation of the effectiveness of the simulation (Bower et al. 2011). We are currently developing and testing a survey-based formative assessment utilizing the SENCER SALG tool available online (http://www.sencer.net/assessment/sencersalg.cfm). A SENCER SALG instrument consists of a pre- and post-course survey taken online that provides instructors with useful, formative feedback for improving their teaching. A SALG instrument provides a snapshot of student skills and attitudes at the start and end of courses, allowing instructors to gauge the effectiveness of teaching strategies, methods, and activities such as the BA simulation (Seymour et al. 2000). A preliminary version of a SALG instrument designed to measure student learning gains resulting from working with the BA simulation has recently been deployed by Bret Bennington and analysis of the results show marked gains from the beginning to the end of the semester (see discussion above). At the next meeting of BA users in the spring of 2014 we will finalize this SALG instrument and begin deploying versions of it to measure the impact of BA on student learning in a variety of educational settings and applications.

Ongoing Work and Future Directions

The tenth in a series of seminars and training sessions for Brownfield Action will be held at Barnard College in April of 2014. Most of the early seminars were devoted to training new users of the simulation and to troubleshooting problems existing users were having. As the simulation evolved, two new versions of BA were produced making the simulation web-based, enhancing the features of the “playing field,” and developing a “modularized” version that is more adaptable to creative new uses. While new users are still being trained, the ninth seminar held in the spring of 2013 was devoted primarily to the sharing of experiences teaching with BA and presenting new applications of BA developed by current users. These included using the data in the BA simulation to teach modeling and analysis using GIS, using the simulation to teach undergraduates about Phase I Environmental Site Assessments incorporating GIS, the use of the gasoline contaminant plume in the simulation as the basis for a six-week unit on toxins and environmental site investigations for high school students, the creation of evaluation tools for the assessment of the effectiveness of BA in an undergraduate hydrogeology course, the modeling of groundwater contaminant plumes from the BA database as part of graduate level student exercises, and discussion of new possibilities for furthering the BA simulation using 3-D gaming technologies.

It is apparent from the above reports that users continue to develop new ways of using BA to teach science in the context of civic engagement. While BA was not developed to teach GIS, the work done in this area suggests that the BA simulation can be easily adapted to enhance GIS instruction. The data- and context-rich virtual world of BA provides an ideal tool for realizing SENCER goals for teaching science through important civic issues and motivating students to learn and understand basic science. Environmental contamination and brownfields are universal problems in today’s world and incorporate civic issues to which every student can relate. BA provides a virtual world and narrative in which students figure out for themselves how to apply basic scientific concepts learned in a course to solve real, practical problems. There is significant potential for further growth of the community of BA users but it is also apparent that BA must undergo significant technological change to bring it up to date with new advances in online delivery and learning technology. A “next-generation” Brownfield Action project is in the early stages of development in order to create a more interactive, 3-D game-based learning environment for the simulation. We would also like to add new data to the simulation, expanding the range of environmental toxins represented to include dense non-aqueous phase liquids (DNAPLS) and nitrates, two major sources of groundwater contamination. Developing the next generation of BA will require funding, and appropriate documentation of learning gains will be needed to make a case for continued investment in BA. To this end we are currently developing standardized student assessment tools using the SENCER SALG that will be deployed across the community of BA adopters. But most importantly, improvement of the Brownfield Action simulation will be facilitated through expansion of the community of instructors who use BA in their courses and who will continue to develop innovative approaches that can be shared across the BA collaborative network.

Discussing the Human Life Cycle with Senior Citizens in an Undergraduate Developmental Biology Course

Abstract

A civic engagement project was designed for undergraduate students in a developmental biology course to promote their understanding of the material as well as its relevance to issues in the local community. For this project, students prepared posters that focused on different stages of the human life cycle: gametogenesis, fertilization, embryonic development, fetal development, childhood (including adolescence), and adulthood (including senescence). Their posters were accompanied by activities designed to further engage the senior citizens who visited during a lab period at the end of the semester. While the senior citizens completed surveys, the students wrote short essays reflecting on the value of the project. The surveys demonstrated an increase in the senior citizens’ understanding of human development and of current issues related to the discipline. The students’ essays revealed that the project was beneficial for many reasons, most notably because it fostered a sense of civic responsibility among the next generation of scientists. [more]

Introduction

Civic engagement is a pedagogical strategy that is successfully employed in a variety of educational contexts (Colby et al. 2003). It is particularly well suited for undergraduates, including those at liberal arts institutions, where the mission often encourages interdisciplinary integration of skills and knowledge to engage with critical issues facing society. The incorporation of civic engagement into specific courses has reciprocal benefits for the students and the local, national, or even international communities to which they belong. Students gain critical insight into specific topics addressed in their coursework while also developing a sense of civic responsibility. In turn, communities may receive benefits when projects promote “quality of life” as envisioned in one definition of civic engagement (Ehrlich 2000). Such projects usually focus on important issues including, but not limited to, poverty, hunger, disease, voter registration, and environmental contamination; moreover, they impact a variety of constituencies, ranging from individuals to groups such as agencies, businesses, and non-profit organizations. While civic engagement manifests itself in diverse ways, there are some common themes, such as clearly defined learning goals and the opportunity for students to reflect carefully on the educational value of the experience. In many cases, academic credit is based on learning and not the on outcome of the project itself (Howard 1993).

Civic engagement is often discussed in the context of coursework in the social sciences. However, it has been argued that it is equally important that such pedagogy be implemented in the natural sciences, for a variety of reasons (Kennell 2000). For example, the projects can provide students with a better sense of how their acquired knowledge is, in fact, relevant to “the real world.” The projects can also help to educate citizens in the local community who have little or no background in the natural sciences, but who must often vote on issues related to the use of stem cells in regenerative medicine, the protection of organisms from the effects of climate change, and the creation of genetically engineered organisms to deal with agricultural pests. In fact, the estimated percentage of citizens who are “scientifically literate” is only 28 percent in the U.S. (Raloff 2010). In addition to promoting scientific literacy, the projects can help to demystify the process by which scientists collect and analyze data, which is important given the results of recent surveys reported by the National Science Board (2012). A variety of effective projects have already been implemented by scientists, including one in which students used emerging technologies as tools in projects related to environmental sustainability and designed to meet the specific needs of their community (e.g. an interactive trail map for a nature preserve prepared using GIS) (Green 2012). In the case of this particular project, the faculty member asked the students to complete surveys, provide anonymous feedback, and write an essay reflecting on their experiences. This project and others provided the inspiration for my own recent initiatives to incorporate civic engagement into advanced biology coursework.

Description of the Service Learning Project

I have incorporated a civic engagement project into a developmental biology course at Denison University, a small liberal arts institution in Granville, Ohio. An undergraduate course in developmental biology usually focuses on model systems—the fruit fly, frog, and chicken, for example— from which biologists have gained insight into the molecular basis of human disease and development. Fertilization, cleavage, and gastrulation are quite complex; accordingly, instructors usually devote several weeks to these earliest stages of embryonic development. In the absence of conversations about issues like stem cell research, however, it is easy for students to lose sight of the “big picture.” I therefore decided to design a project that would allow students to “come full circle” at the end of the semester by having them engage in a conversation about the human life cycle with local senior citizens. I chose to have the students work with senior citizens since many of the campus outreach programs are focused on local youth. In addition, I expected that the senior citizens would have many interesting, relevant experiences to share with the students, and that they would be a more appropriate audience given the nature of the course material.

For the project, I divided my 24 students into six groups, each focusing on one stage of the human life cycle: gametogenesis, fertilization, embryonic development, fetal development, childhood (including adolescence), and adulthood (including senescence). I provided each group with a poster template with three sections titled “Concept,” “Concept Explained,” and “In the News.” In the “Concept” section the students defined their stage in no more than two or three sentences, while in the section titled “Concept Explained,” the students provided more detailed information and, in some cases, divided their stage into several distinct steps (e.g. sperm attraction, acrosome reaction, fusion of the plasma membranes, prevention of polyspermy, activation of egg metabolism, and fusion of the genetic material, in the case of fertilization). Finally, in the section titled “In the News,” the students provided information on one recent issue, debate, or controversy related to their stage (in the case of fertilization, for example, the availability of a male contraceptive). In addition to the poster, I asked the students to develop a simple activity to further engage their audience. I provided them with a few ideas—completing a quiz, watching a short video on a laptop, and examining eggs, embryos, and/or larvae under a microscope—although I encouraged the students to think creatively about other options to facilitate learning. As the final component of the project, the students wrote a short essay on the value of civic engagement in the context of a liberal arts education and one thing they learned from their interactions with senior citizens. I was particularly interested in having them reflect on the value of this educational strategy in the natural sciences.

Other than providing them with a poster template, I offered little or no guidance to the individual groups; the students assumed responsibility for their poster displays as well as for the tasks required to prepare for the arrival of the senior citizens. During their visit, student volunteers escorted the senior citizens from one station to the next, giving them at least ten minutes to learn about each stage of the human life cycle. In many cases, the senior citizens were so engaged with the material that they remained at a station for much longer in order to ask questions and/or have an extended conversation with the students. The students ensured that there was sufficient seating in front of each poster display, since many of the senior citizens spent a total of about two hours rotating through the different stations. They had learned about this opportunity through an e-mail sent to retired staff or through an advertisement in the local newspaper, although a few were recruited from a local senior center by the John W. Alford Center for Service Learning at Denison. Snacks were purchased from the Smiling with Hope Bakery, which is run by special-needs students at Newark High School in Newark, Ohio.

Outcomes of the Service Learning Project

In an effort to assess the senior citizens’ learning, I prepared a short survey in which they rated their understanding of 1) human development, and 2) current issues in developmental biology both before and after visiting the poster displays. A total of 17 local senior citizens were recruited for the project, with thirteen of them completing the survey at the end of the afternoon (Table 1). In both cases, there was a statistically significant increase in their understanding, with several individuals offering positive comments about the experience, either through e-mail or through comments at the bottom of the survey. Indeed, students noted in their essays that the senior citizens were “focused,” “inquisitive,” and “enthusiastic,” with “a genuine interest in learning.” As the afternoon progressed, I came to realize that the senior citizens were modeling the idealistic concept of “lifelong learning” for my students through their intellectual engagement (McClure 2013).

To assess the students’ learning, I evaluated their poster displays and the essays that they wrote following the senior citizens’ visit. Since this was a pilot project, each component was worth only five percent of their final grade in the course. As I had expected, many students indicated that teaching what they had learned in the course helped them to gain a more complete understanding of important concepts in developmental biology. On a related note, they recognized civic engagement as an effective strategy to improve upon their communication skills. Many students also appreciated the opportunity to leave the “bubble” of campus life and interact with members of the local community, while learning how to “effectively converse [with them] about key issues facing society.” However, the students’ essays revealed that the project was beneficial in ways that I could not have predicted. For example, many students described their initial uncertainty about the value of civic engagement, but then wrote about how they came to view it as an “innovative way to incorporate many themes from our mission statement” and “a prime example of the types of endeavors [the institution] should continue to pursue to more fully provide its students with a liberal arts education.” They recognized it as an opportunity to “interact with diverse groups of people” and to “facilitate [their] growth into change makers that will work to fix the problems faced by humanity.” Several of them even described how rewarding it was to communicate knowledge with those who may not have had the opportunity to pursue an undergraduate education, noting their status as “privileged students,” who have a responsibility to “share [their] experience with others.”

Conclusions

I was quite satisfied with the extent to which the students reflected on the project and expressed “joy” (in their own words) in having the unique opportunity to engage with the local community as part of a biology course. In the future, I hope that this project will be extended to senior citizens from more impoverished communities, perhaps with students actually meeting them at a retirement facility. In addition, I hope to design alternative projects that address senior citizens’ specific interests (besides the human life cycle), since some of our visitors indicated on their surveys that they wanted to learn more about such topics as environmental influences on aging. And finally, I hope to encourage my peers to consider incorporating a civic engagement project into their own courses, since this educational strategy obviously has much to offer to students in the natural sciences, even in the realm of cellular and molecular biology. It can be easily accomplished during a single lab period, although it can be more extensive with activities spanning one or more semesters (e.g. Hark 2008; Imoto 2013; Larios-Sanz et al. 2011; Santas 2009). Regardless of the size and scope of the project, civic engagement can transform students’ thinking and inspire them to make important contributions to the world, whether as a nurse, teacher, or conservation biologist. It should be an integral component of every academic institution, “across all fields of study” as the National Task Force on Civic Learning and Democratic Engagement has declared (2012). In summary, I would argue that scientists have an important role to play in developing students’ sense of civic responsibility in the 21st century.

Meeting the Challenge of Interdisciplinary Assessment

 

Introduction to Interdisciplinary Education

“As the pace of scientific discovery and innovation accelerates, there is an urgent cultural need to reflect thoughtfully about these epic changes and challenges. The challenges of the twenty-first century require new interdisciplinary collaboration, which place questions of meanings and values on the agenda. We need to put questions about the universe and the universal back at the heart of university.” William Grassie (2013)

As the world becomes more complex, given the rapid expansion of technology, the changing nature of warfare, rising energy, and environmental crises, the value of an interdisciplinary education is increasingly obvious. Social, political, economic, and scientific issues are so thoroughly interconnected that they cannot be explored productively, either by experts or students, within clear-cut disciplinary boundaries.

Despite this fact, several problems arise when institutions try to incorporate interdisciplinary education into their programs. Boix Mansilla (2005) noted that the assessment of interdisciplinary work by students is of great concern. She explains that because faculty are often discipline-specific experts, they are unfamiliar with disciplines outside their realm of expertise and have difficulty defining interdisciplinary work. She goes on to explain that, as a consequence, “the issue [of standards] is marred by controversies over the purposes, methods, and most importantly, the content of proposed assessments” (2005, 16).

This paper offers one solution to this dilemma. The following analysis explores the current state of interdisciplinary education, both in academia broadly, and specifically, at West Point through its interdisciplinary Core Program. The sections that follow will highlight the current issues inherent in interdisciplinary education, define interdisciplinary education objectives, and finally, explain the adaptable, multi-functional, interdisciplinary rubric being implemented at the United States Military Academy (USMA), a rubric designed to resolve many of the issues interdisciplinary educators encounter.

The Current State of Interdisciplinary Education in Academia

The demand is clear. Whether we try to take a stance on the stem cell research controversy, to interpret a work of art in a new medium, or to assess the reconstruction of Iraq, a deep understanding of contemporary life requires knowledge and thinking skills that transcend the traditional disciplines. Such understanding demands that we draw on multiple sources of expertise to capture multi-dimensional phenomena, to produce complex explanations, or to solve intricate problems. The educational corollary of this condition is that preparing young adults to be full participants in contemporary society demands that we foster their capacity to draw on multiple sources of knowledge to build deep understanding.” Veronica Boix Mansilla (2005, 14)

There are currently several studies, including evaluation measures, defining the essence of interdisciplinary education. The above quote from Boix Mansilla’s “Assessing Student Work at Disciplinary Crossroads” highlights the challenge educators are experiencing in preparing students to meet today’s most pressing problems. This paper will not attempt to address the structure of interdisciplinary education as an institutional convention, but only to define the essential skills and capacities that a student with interdisciplinary understanding would demonstrate. These definitions are essential to understanding and creating a framework for interdisciplinary learning, which is arguably the first step in adequately integrating it into educational programs. Interdisciplinarity is a difficult construct to quantify, and many educators have been unable to frame a definition of it or to assess it in student work. As a consequence of these and other challenges, only a limited number of colleges or universities have implemented formal interdisciplinary programs at the institutional level.

Several analyses (Boix Mansilla 2005; Boix Mansilla and Dawes Duraising 2007; Rhoten et al. 2008; Stowe and Eder 2002) address the key issues surrounding interdisciplinary learning in higher education and offer proposals on how to address them, starting with the definition of the term “interdisciplinary.” One definition of interdisciplinary understanding is “the capacity to integrate knowledge and modes of thinking drawn from two or more disciplines to produce a cognitive advancement—for example, explaining a phenomenon, solving a problem, creating a product, or raising a new question—in ways that would have been unlikely through single disciplinary means” (Boix Mansilla 2005, 16; Boix Mansilla and Dawes Duraising 2007, 216). A definition is particularly important because “a clear articulation of what counts as quality interdisciplinary work, and how such quality might be measured, is needed if academic institutions are to foster in students deep understanding of complex problems and evaluate the impact of interdisciplinary education initiatives” (Boix Mansilla 2005, 16). An agreed-upon definition is currently lacking in academia, and this has resulted in inconsistent grading, teaching, and learning in interdisciplinary education.

One study of well regarded and established interdisciplinary programs in the U.S., which included Bioethics at the University of Pennsylvania, Interpretation Theory at Swarthmore College, Human Biology at Stanford University, and the NEXA Program at San Francisco State University, involved “69 interviews, 10 classroom observations, 40 samples of student work, and assorted program documentation” (Boix Mansilla and Dawes Duraising 2007, 4). The data were gathered in one-hour to 90-minute semi-structured interviews with faculty and students inquiring about the manner of assessment used in their respective programs. Next, examples of student work were used to give examples of what the institution viewed as meeting the definition of interdisciplinarity. From the interviews and student examples, the authors concluded that there are three core dimensions to student interdisciplinary work: disciplinary grounding, advancement through integration, and critical awareness (Boix Mansilla, 2005, Boix Mansilla and Dawes Duraising 2007). These core elements are represented graphically in Figure 1.

Figure 1. Three Interrelated Criteria for Assessing Students’ Interdisciplinary Work (Boix Mansilla and Dawes Duraising 2007, 223)

The first core element in Figure 1, disciplinary grounding, calls for strong base knowledge in individual disciplines. During the interviews, 75 percent of the interviewed faculty felt that strong subject-area knowledge was necessary for interdisciplinary education that did not sacrifice depth in exchange for breadth. However, the authors noted that the key to successful disciplinary grounding also included the thoughtful selection of which disciplines to use and how to use them. Advancement through integration, the second principle, is universal in all student work in the sense that students are supposed to learn from the work they do; however, what sets it apart in interdisciplinary education is that “students advance their understanding by moving to a new conceptual model, explanation, insight, or solution” (Boix Mansilla and Dawes Duraising 2007, 225). In the study, sixty-eight percent of faculty identified advancement through integration as a necessary element in interdisciplinary understanding and as the quintessential element for the advancement of student understanding. However, various programs and their students interpret this core element differently. For example, some students in in the NEXA Program at San Francisco State University strive for complex explanations, which evaluate the extent to which disciplines are interwoven to create a broad picture of how interconnected different disciplines are on a given topic. Other students in the same program prefer to use aesthetic reinterpretations to connect the literary, historical, and social elements of a given topic. Other students, such as those in the Bioethics program at the University of Pennsylvania, choose to focus on the development of practical solutions based on of the use of multi-disciplined ideas. The final principle from Figure 1, critical awareness, refers to student work being able to withstand examination and criticism and explicitly calls for evidence of student reflection in their work. Student work needs to “exhibit clarity of purpose and offer evidence of reflective self-critique” (Boix-Mansilla and Dawes Duraising 2007, 228).

Rhoten et al. (2008) also conducted a study focused on the similarities and differences between the learning outcomes of liberal arts and interdisciplinary programs. For this particular study, the researchers used student and faculty surveys, interviews, and tests to gather data for their analysis. The authors explain that most liberal arts programs “must develop student capacities to integrate or synthesize disciplinary knowledge and modes of thinking,” which is very similar to the type of synthesis that is expected from an interdisciplinary curriculum (Rhoten et al. 2008, 3–4). The main purpose behind this study was to identify the parallels between interdisciplinary and liberal arts programs, in order to show how a program can be made more interdisciplinary without changing its structure or content. Table 1 shows a summary of several parallels between a liberal arts education and an interdisciplinary education.

Table 1. Comparison of Liberal Arts Education and Interdisciplinary Education Objectives (Rhoten et al. 2008)

Rhoten et al. (2008) also analyzed empirical data to draw out trends on the “222 institutions considered ‘Baccalaureate College-Liberal Arts institutions’ under the 2000 Carnegie Classification system,” whether the interdisciplinary programs offered were majors, minors, optional courses, or required courses (Rhoten et al. 2008, 5). In general, “interdisciplinary programs are still ‘personally driven,’ whereas departments are ‘self-perpetuating'” (Rhoten et al. 2008, 6). “Personally driven” simply means that if students want to broaden their subject-area exposure they must do so on their own. “Self-perpetuating” refers to fact that departments within an institution need to act in their own self-interest in order to survive and thrive; therefore they tend to avoid interdisciplinary efforts. Interdisciplinary education does not support the mission of individual departments, and if students seek it, they must do so on their own initiative. One would therefore conclude that the only way to truly incorporate interdisciplinary education into schools is by making it institutionally mandated, at least for the core curriculum that all students are required to take.

Schools should strive to integrate interdisciplinary efforts into their institutions because “interdisciplinarity breeds innovation” (Rhoten et al. 2008, 12). Although such innovation carries tremendous benefits, the difficulty of measuring student and educator success was again identified as a barrier. Most schools that are already making efforts towards interdisciplinarity believe that they are somewhat successful according to Rhoten et al. (2008). However, in order to mark and measure success, and to continually improve interdisciplinary programs in schools, the authors propose a value-added assessment, which is intended to provide an “assessment regime that measures growth that has occurred as a result of participation in the institution or academic program” (Rhoten et al. 2008, 14). Moreover, some cross-cutting goals that are embedded especially in interdisciplinary studies, such as life-long learning, curiosity, creative thinking, synthesis, and integration, have acquired the reputation of being ineffable and, correspondingly, unassessable” (Rhoten et al. 2008, 83). This common problem was addressed by Stowe and Eder (2002) who identified several assessment measures that are placed on a continuum, as seen in Figure 2. These measures can also be used to better define interdisciplinary standards by providing a multi-tiered adjustable scale that can help to quantify the assessment of student work based on an instructor’s desired outcomes.

Figure 2. Perspectives on Assessment (Stowe and Eder 2002, 84)

Stowe and Eder (2002) state that using a rubric to define and measure interdisciplinary work would improve the “apparently subjective nature” of interdisciplinary assessment. They further recommend the rubric as a “visible standard—a scoring guide—that allows the assessor and the public, for that matter, to recognize expectations and make increasingly fine distinctions about the quantity and quality of student learning” (96). They expand on their recommendation by noting that assessment must be focused on both improving interdisciplinary learning and “improving student learning,” and should be “embedded within larger systems… and create linkages and enhance coherence within and across the curriculum” (80). Without cooperation across different programs, it is impossible to foster an interdisciplinary learning environment.

An example of such cooperation can be seen at USMA, where several academic departments have moved towards a cooperative environment focused on interdisciplinary learning (Elliott et al. 2013). This paper will focus on the education of the USMA Class of 2016 from their freshman year, when the plan to use energy conservation and the NetZero project (an energy initiative by the Dept. of the Army on several Army posts, including West Point, to produce as much energy as it consumes by the year 2020) was adopted to infuse interdisciplinary themes into their core courses. The five Student Learning Outcomes from this effort include four individual discipline-focused outcomes as well as a fifth, which aims to “develop an interdisciplinary perspective that supports knowledge transfer across disciplinary boundaries and supports innovative solutions to complex energy problems/projects” (Elliott et al. 2013, 33). In a larger sense, this objective illustrates that interdisciplinary education addresses the mission of USMA and the Army’s focus on the “development of adaptive leaders who are comfortable operating in ambiguity and complexity will increasingly be our competitive advantage against future threats to our Nation,” as outlined by General Martin Dempsey, Chairman of the U.S. Joint Chiefs of Staff (Elliiott et al. 2013, 30).

Framing the Problem

The Academy produces graduates who can think dynamically in the ever-changing world described in the quotes from Grassie and Boix Mansilla at the beginning of this article. At West Point, this is accomplished by taking not only a multi-disciplinary approach to education, but also an interdisciplinary one. The Academy’s Core Curriculum describes the required classes that all cadets must complete or validate. The Core Curriculum does not include any classes required for a cadet’s major. Other non-academic requirements include three tactics courses and seven physical education courses. The interdisciplinary aspect is a new addition to the curriculum. In recent years, several committees have recommended promoting interdisciplinary approaches to better meet both the Academy’s and the Army’s goals as outlined in Elliott et al. (2013).

To achieve these goals, several academic departments involved in the Core Curriculum developed an interdisciplinary program for the entering plebe class, the Class of 2016. During the first week of classes, freshmen wrote an essay in their Introduction to Mathematical Modeling course, or MA103, about how they would use concepts from different courses to tackle the challenges that NetZero and the alarming problem of energy consumption in the Army pose to West Point. After 30 instruction sessions (approximately thirteen weeks), the freshmen revised these essays in their Composition course EN101. This time they used the knowledge acquired throughout the semester in the English course and in the other courses they were taking. Faculty from the Department of Mathematical Sciences and the Department of English and Philosophy evaluated these revised essays from different perspectives to emphasize the importance and relevance of multiple disciplines. This led to the realization that it was impossible to adequately compare the essays, since the assignments, rubrics, and faculty were not consistent and there was no common rubric to standardize the grading approach. To mitigate this challenge, the essays were compared in our study using the Flesch-Kincaid test (a formula designed to evaluate the difficulty and complexity of technical writing. It consists of two readings: grade level and reading ease) and a comparison of the final grades for the various essays. Scores for a sample of three essays for 25 students, a total of 75 essays, were used to compare improvement in a measureable, quantitative manner. The test consisted of a null hypothesis that there was no significant difference among the ratings, indicating neither improvement nor deterioration of scores from the different assignments throughout the semester, and an alternative hypothesis that there actually was a difference between scores. A two-tailed t-test yielded p-values ranging between 0.3 and 0.6. This indicated that the Flesch-Kincaid results were inconclusive, meaning that neither the null nor the alternative hypothesis could be rejected.

Despite the inconclusive results of the Flesch-Kincaid test, there was a demonstrated improvement in student work, albeit an improvement that was perceived on the basis of a subjective analysis of the essays. Therefore, a new rubric was developed to re-grade all of the essays in a standardized fashion against the desired elements for that particular set of assignments. To facilitate a comparison, this new and straightforward rubric aimed at grading each assignment from the different departments on the same scale. The grades were on a 1–10 scale, and the rubric can be seen in Table 2. The essays were then re-graded according to the same rubric and the results were compared again using a two-tailed t-test.

The challenge in evaluating interdisciplinary work is that the term “interdisciplinary” is not well-defined or broadly understood. This became even clearer after the Chemistry faculty conducted an interdisciplinary group capstone in the General Chemistry course with the Class of 2016 during the second semester of their freshman year. The capstone presented the students a complex and challenging energy problem that was both current and militarily relevant to their future roles as Army officers. This project required groups of students to write a memorandum summarizing their findings on an experimental, portable, and green battery recharger for soldiers in the field, and then to provide a presentation of their results to their commander. Cadets conducted an experiment on the battery recharger to test its efficiency, to compare it to current recharging methods, and to address the social and leadership challenges that would occur when this new equipment was integrated into a unit. In addition, the capstone leveraged the students’ various courses and experiences to scaffold understanding of key concepts and technology necessary to engage the problem. The freshman cadets were expected to utilize what they learned from math modeling, information technology, general psychology, and general chemistry courses in formulating their solution.

The rubric used to grade these capstones was developed by the Chemistry faculty with input from all the participating courses, and then later utilized by the Chemistry faculty in assessing the capstones. The collaborative rubric identified numerous concepts in each course, and as a result, it was several pages long. Perhaps most significantly, it did not define the term “interdisciplinary” for the faculty and the students in the capstone, nor did it make clear the associated expectations. At the conclusion of the rubric, faculty were asked to rate on a 1–10 scale how interdisciplinary their students’ submissions were. The results, displayed in Figure 3, had a standard deviation of .186 and were inconsistent in both the average instructor rating and the range of different ratings faculty assigned. This indicated that the faculty did not share the same understanding of “interdisciplinary” in assessing student work.

Table 2. Rubric used to evaluate the population sample of NetZero essays from fall 2012

Boix Mansilla and Dawes Duraising (2007) state that student interdisciplinary work should “be well-grounded in the disciplines” “show critical awareness,” and “advance student understanding” (223). These criteria both define the basic learning objectives of an interdisciplinary education and address the need for baseline knowledge in the subjects being addressed in student work. While these criteria may not be included in a rubric or other grading mechanism, they provide more of a defined objective regarding interdisciplinary student work.

Although the idea of graduating interdisciplinary-minded students is appealing to many programs, the challenge of measuring the success of interdisciplinary curriculums in producing these “multi-disciplined” graduates has yet to be addressed. The problem of scaling and measuring interdisciplinary education is itself interdisciplinary in nature and, consequently, an abstract idea for many (Boix-Mansilla and Dawes Duraising 2007, 218). Interdisciplinary education evaluation currently lacks a “sound framework” for assessment since the effects of interdisciplinary efforts on student learning are neither well-defined nor proven (Boix Mansilla 2005, 18). As seen in Figure 2 (Stowe and Eder 2002), the assessment of interdisciplinary work is a non-static scale where the balance between the perspectives and entities is never quite the same from project to project, or from class to class. Stowe and Eder (2002) offer a flexible scale for assessment that allows each interdisciplinary quality to be judged according to faculty expectations: how discovery-oriented versus objective-orientated do they want student assignments to be? Rhoten et al. (2008) do correlate several common learning outcomes of a liberal arts education with their interdisciplinary counterparts as seen in Table 1. Although useful for demonstrating extensive possible outcomes and correlations, the linkages are broadly defined and do not specify objectives; this exemplifies the issues of scale, definition, and the non-quantified nature of interdisciplinary education that currently prevail in academia.

All of the aforementioned problems can be traced to a lack of clarity on standards (Boix-Mansilla 2005, 16). Stowe (2002) explicitly calls for a standard for grading, collecting data, and creating a shared understanding, which he suggests could be found in a rubric. A standardized rubric, which is adaptable to several mediums and is general enough to be applicable to several disciplines, is desperately needed for evaluating and assessing interdisciplinary work. Such a rubric needs to clearly define the necessary elements of an interdisciplinary product and be sufficiently adaptable to align with project requirements; this would resolve several of the problems we have identified. In addition, Stowe and Eder (2002) call for the inclusion of very specific elements in a rubric, so that it can address current problems and properly evaluate interdisciplinary work. Among these requirements are assessing complex intellectual processes, promoting objectivity, reliability, and validity in assessment, clearly defining learning objectives for students, and being flexible and adjustable for course or curriculum progression (96). Although we conducted a thorough search, we failed to find a rubric that adequately fulfills this need.

Interdisciplinary Rubric Development

The goal of the rubric developed at USMA is to create a grading mechanism that can be used in multiple project mediums across multiple disciplines. Simultaneously this rubric maintains the integrity of the interdisciplinary goals by creating a more defined standard with which to grade interdisciplinary student work. The rubric also contains open areas for point allotment as well as weighting for each category, which allows faculty to allot points and focus where they see fit. Developing such a rubric required several steps: defining the term interdisciplinary, identifying the elements that student work needs to demonstrate in order to illustrate interdisciplinary thinking, creating a model that visually represents the interconnectivity of these elements, and then using the defined elements and model to arrive at the rubric categories.

The first step in the rubric development process was to define the term interdisciplinary:

Interdisciplinary: The seamless integration of multi-dimensional, multi-faceted ideas into a clearly demonstrated understanding of an issue’s breadth and depth, with sound judgment and dynamic thinking.

Boix Mansilla’s definition of interdisciplinary understanding provided the starting point for the development of the rubric. Additionally, material from the research discussed above identified missing elements from Boix Mansilla’s definition. For example, the best students’ interdisciplinary work included ideas from multiple disciplines that were integrated to demonstrate the level of understanding that the student has attained.

The second step in the rubric development process was to expand the definition of interdisciplinary, in order to create a shared understanding between students, faculty, and those evaluating the interdisciplinary work. To this end, the feedback and lessons learned from previous student work were used to identify the elements common to successful interdisciplinary work. These principles include: discipline specific knowledge, multi-perspective understanding, integration, practical integrated solutions, reflection, and clarity of purpose. To illustrate the interconnectivity of these principles, a conceptual model of the characteristics was created. Initially, the intention was to create a linear model to represent the core principles. However, several issues, such as missing connections and limited complexity, led to the immediate conclusion that a linear model could not completely describe complex nonlinear problem solving. The resulting model, which illustrates a cyclical thinking process, is shown in Figure 4.

Figure 4. The Cyclican Model of the Key Interdisciplinary Characteristics. This model demonstrates the interconnectivity of the d defined interdisciplinary elements.

The model begins with the framing and scoping of the problem before the application of discipline-specific knowledge, which as we have seen is an essential starting point for interdisciplinary work. The core principle of the integration of ideas was partitioned into multi-perspective understanding, integration, and practical integrated solutions. Multi-perspective understanding and discipline-specific knowledge are connected by an addition sign, which symbolizes understanding a topic from multiple perspectives. This illustrates that students must be able to use discipline-specific knowledge to make this essential connection. The arrow labeled “integration” in the lower part of the model represents the synthesis of discipline-specific knowledge and multi-perspective understanding into practical integrated solutions. Practical integrated solutions are then connected to reflection via a multiplication sign to show that reflection has a multiplicative effect on interdisciplinary understanding. The arrow labeled “clarity of purpose” represents the cyclical process and shows the compilation of all the previous elements back into discipline-specific knowledge. The knowledge gained from the various parts of the cycle can be used in the further learning of other applicable disciplines. This model’s goal is not to explain the rubric, but to illustrate how interdisciplinary education is cyclical in nature, how the characteristics of interdisciplinary understanding are relevant to interdisciplinary education, and how student learning should continue to build.

Next, the core principles of what makes student work interdisciplinary were established, defined, and examined. The elements in Figure 1 above, taken from Boix Mansilla and Dawes Duraising (2007), were used as a starting point for the development of this rubric’s core principles: be well grounded in the disciplines, show critical awareness, and advance student leaning through understanding (223). For the purpose of this rubric, some elements were modified and expanded to create six core principles. A list of the six core principles that were incorporated into the rubric, along with their definitions, appear in Table 3.

Problem framing and scope are derived from the idea that interdisciplinary work should show critical awareness. The definition used in the rubric is very flexible, so that educators can adapt it for different project mediums and faculty, departments, and/or university requirements. Critical awareness, as defined by Boix Mansilla (2007), includes the definition of purpose as well as the integration of ideas. The definition used for problem framing and scope in the rubric requires that the student’s work have a clearly defined purpose. This was created as a separate category because we had observed a clear trend of misunderstanding among faculty regarding the level of complexity that they expected. This is an important aspect of student interdisciplinary understanding; it allows the faculty to scale assignments according to the expected level of student understanding and allows the student to recognize just how complex and multi-disciplined a product the instructor is seeking. For example, if students were assigned a project on how to effectively stock a warehouse, an instructor would not have the same expectations of a freshman who has taken only introductory courses in mathematical modeling and economics as of a senior who had taken nonlinear optimization, supply chain management, and microeconomics courses. Having this requirement in the rubric makes clear the expectation that students will properly identify what they want to address, and also allows the instructor to have a frame of reference in a project.

The rubric’s second core principle, discipline knowledge is well grounded in the disciplines and is intentionally more open-ended, so that it can be readily adapted to different departments, projects, and situations (Boix Mansilla 2007). Identifying theories, examples, findings, methods, etc. may not be relevant or necessary in a given problem. Therefore, although the evaluator is given an area in the rubric that calls for disciplinary knowledge, the rubric does not explicitly indicate how that knowledge is to be graded. For example, in our warehouse stocking project, a freshman might be expected to mathematically model the effects of changing employee wages on productivity. A university senior, on the other hand, might be expected to produce a business recommendation to stakeholders by addressing the intricacies of supply chain management on warehouse profits as well as its psychological implications for employees. The discipline knowledge area of the rubric enables the evaluator to determine how much knowledge and understanding students are expected to demonstrate, while ensuring that the importance of disciplinary understanding is not lost on an interdisciplinary project.

The integration of ideas principle is really the quintessential element for the interdisciplinarity of this rubric. All six core principles are important interdisciplinary factors, but if this element were removed, the rubric could be used for a project that is not interdisciplinary. Integration of ideas derives its meaning from the critical awareness and advanced student understanding pieces identified above in Figure 1. This rubric defines integration of ideas as multi-dimensional, feasible, practical solutions with multi-faceted and seamlessly connected ideas. It is important to note the difference between being integrated and being seamlessly integrated. The seamless integration of ideas, which can take on different meanings depending on the assignment, is an indicator of true multi-dimensional, multi-faceted understanding. Seamless integration. We define the term seamlessly integrated to mean that ideas are not simply laundry-listed, but instead are connected in an intelligent and logical fashion. The definitional elements of multi-dimensional and multi-faceted identify the need for complexity in student work. It is multi-dimensional when students make use of multiple dimensions of their education or, in other words, use multiple disciplines, in their work. Multi-faceted means that students are able to use evidence and knowledge to back up their multi-dimensional claims. The most important component is that students be able to demonstrate a clear understanding of what they are presenting. This also relates to a student’s ability to demonstrate the span of an issue’s breadth and depth. In other words, students should be able to apply disciplines to an issue or topic with an appropriate understanding of the level of each of the disciplines. The use of extraneous disciplines merely for the sake of incorporating more disciplines does not necessarily make student work interdisciplinary. In fact, it contradicts the idea of advancing the complexity of the student’s thought process.. Students who apply the appropriate level of discipline breadth and depth indicate their ability to use sound judgment or logic, as well as their ability to think dynamically.

The next two core principles, clarity of purpose and reflection, were added to address the students’ failure to internalize what they were learning and understanding; this was revealed during the analysis of the USMA interdisciplinary program. The main challenge was that students did not fully grasp why a given project was interdisciplinary, or why that was important. To alleviate this, the core principle clarity of purpose was added to the rubric to help students understand the “why”; the intent was to motivate them to define the purpose of their investigation and to take an in-depth approach to the problem. This is different from problem framing and scope in a very important way: problem framing and scope focuses on a well-defined thesis statement or purpose statement, whereas clarity of purpose focuses on the content of student work. In other words, problem framing and scope ask whether students have a clearly stated framework for their project, while clarity of purpose asks whether they demonstrate their personal interdisciplinary understanding and then explain it well to their audience. Similarly, the next principle, reflection, calls for a clear and delineated connection of ideas and an indication that students have reflected on the interconnectivity and importance of their areas of study. These two core principles are drivers of internalization and cognitive advancement in interdisciplinary learning. They are particularly important because often students do not reflect on what they have learned. The reflection piece is intended to facilitate a deeper understanding of what they are learning and to encourage students to consider how the material fits into the greater scheme of their education.

The final element of the rubric shown in Table 3 is the presentation principle. This principle calls for information that is presented in a suitable medium with proper tone, word choice, spelling, grammar, etc. In short, did the students address the audience correctly and present their knowledge intelligently while doing so? This section can be adapted to the type of project and course for which the rubric is being used. For example, English faculty would probably expand this section because of its importance to their learning outcomes, whereas chemistry faculty may place more emphasis on the discipline-knowledge portion.

The newly developed rubric was presented to the Math course leaders for use on the freshman’s “mini” capstone exercise in December 2013. The rubric was sent to the faculty with minimal guidance. The feedback from the course director made it clear that the students and faculty did not fully grasp the intention or expectations behind the rubric. A few factors contributed to this: sixty-six percent of the faculty were new to the department; the interdisciplinary expectations were not fully explained to the faculty; although everyone received the rubric, each instructor created his or her own rubric for the mini-capstone; and the students who took the mini-capstone and the faculty who graded their work were under significant time pressure. The mini-capstone in its creation, execution, and grading was not given adequate time due to end of semester requirements at USMA during the November-December time period. An important conclusion from this feedback was that the faculty needed to have a common understanding of what is expected on an interdisciplinary project. To achieve this for the General Chemistry capstone project in the spring of 2014, a grading calibration exercise was conducted. This calibration included good and poor examples of interdisciplinary work from the previous year’s chemistry capstone, and showed faculty how to distinguish between good and poor work and how to use the rubric in assigning a grade.

Implementing the Interdisciplinary Rubric

The first step in implementing the rubric was calibration with the faculty. With such an exercise, the faculty should take away a common understanding of what exactly interdisciplinarity is as well as the knowledge of what constitutes a good final project. The plan for the calibration exercise developed for USMA faculty who would be grading the CH102 General Chemistry capstone in the spring of 2014 was an hour-long presentation and discussion. Prior to the presentation, faculty received a packet of examples of cadet work in each of the major portions of the previous year’s capstone project. The examples included “A” work as well as examples of common integration errors students make: the “laundry list,” the “tacked on at the end,” and the “no real knowledge” integration errors. The “laundry list” is an example of how a student may mention and be knowledgeable in multiple disciplines but does not integrate them, providing instead a “laundry list” of the different disciplines and explaining the relevance of each individually. The “tacked on at the end” error (or whatever we may call it) exemplifies how a student may go in-depth in one discipline, particularly in the discipline for which the assignment was given, then tack on a sentence or two at the end mentioning other disciplines in order to call the project interdisciplinary. The “no real knowledge” example presents a plethora of ideas but does not demonstrate that the student learned or integrated disciplines and/or ideas. With these examples, faculty became more familiar with what correct and incorrect work looked like. The “A” level example was not meant to illustrate the perfect or only solution; it was merely one example. Faculty evaluated each example using the standard A, B, C, D, F grading scale based on how interdisciplinary they felt each project was.

At the start of the presentation portion of the rubric calibration, faculty were introduced to the interdisciplinary characteristics and model from Figure 4. This ensured understanding of interdisciplinary characteristics prior to the introduction to the rubric itself. After the characteristics were covered, the results from the exercise, which the faculty just had completed, were discussed. This clarified any misunderstandings that faculty had about the interdisciplinary characteristics, while the examples of chemistry capstones from the previous year provided a frame of reference. Next the rubric was thoroughly explained, showing how it was scalable, expandable, and concise to meet instructor needs for interdisciplinary student projects.

The General Chemistry capstone rubric for 2014 differs from its 2013 predecessor in two very important ways. First, it is significantly shorter; its two pages (compared to seven pages) emphasize quality over quantity. Instead of listing every detail of the project, the new capstone rubric has five categories that address the math modeling, leadership, information security, oral communication, and the required submission components of the project, all without specific details. This allows the students to be more creative in their answers to the given problem.

The 2013 rubric was not based on any interdisciplinary principles or examples. Instead, it listed specific requirements from the disciplines the students were supposed to integrate. The result was quite the opposite: the 2013 capstone projects tended to be disjointed because of the slew of specific requirements. This year’s capstone rubric incorporates the interdisciplinary principles described in Table 3.Problem framing and scope is addressed in the Project Summary section with the requirement for a bottom line up front (BLUF), or thesis. Discipline knowledge is asked for in the Discrete Dynamic Modeling, Persuasion and Conformity in a Leadership Environment, and Information Security sections. Although the course-specific requirements must be addressed, Integration of ideas is assessed in the Oral Communication and Project Summary sections, which requires that fluid transitions and logically ordered and related ideas be integrated. Appropriate presentation is also adequately addressed in these sections, as the rubric lays out clear expectations of the written and oral presentations for students, including their tone, body language, and level of professionalism. Clarity of purposeand reflectionare asked for in the Project Summary section, which calls for contingency plans and thoroughly explained analysis of the total problem.

Initial instructor feedback on the use of this rubric is that it better defined expectations for the students’ interdisciplinary work, for both the instructor and the students. After using the rubric in the calibration exercise, instructors stated that they felt more confident and prepared than they had in 2013 when there was no such exercise and assessment tool available; this year they understood what was asked of them and of the students. Initial comparisons of the interdisciplinary assessments of the students’ work from 2013 and 2014 are quite positive. On a scale of 0–10, the average interdisciplinary score given by instructors was 5.69 in 2013, with zero being the least interdisciplinary and 10 the most. (See Figure 3 for these data.) In 2014 this improved to 7.79 (actually 15.5/20). There was also less variability between instructors. For example, in 2013 the standard deviation of the mean scores assigned by each of the instructors was 1.86 (Figure 3). In 2014, the standard deviation between the instructors’ mean scores was .98 (1.96/20), a decrease of over 47%.

Future Work and Conclusion

Now that the General Chemistry capstone for USMA Class of 2017 has concluded, several analyses must be completed to evaluate the progress of interdisciplinary education at USMA. At a minimum, an analysis of the grades and feedback from the students and faculty needs to be conducted. The analysis of the grades should include a distribution of grades compared with their expected distribution, as well as a quantitative and a qualitative analysis of the capstones compared to the previous years’ capstones. This could be done using the methods previously employed, including the use of Flesch-Kincaid, paired t-test, the distribution of the faculty’s interdisciplinary rating similar to Figure 3, and/or a cross-course sample of projects re-graded by the course director.

The discussion and research that have taken place at West Point since the first General Chemistry capstone project in 2013 indicate that the results of this year’s changes should be positive. Although there is as yet no statistical evidence to demonstrate improvement, the general understanding of how interdisciplinarity looks, how to produce it, and how to assess it is much more expansive now than in 2013. The reason for this might be that faculty and students at USMA are now experienced with interdisciplinary work and have a clearer understanding of interdisciplinary assessment and its importance over the course of a year.

The world is a complex and rapidly changing place that requires its future scientists, scholars, engineers, teachers, and leaders to think dynamically and across disciplines.. Interdisciplinary assessment is necessary for the future of education, particularly at West Point where we recognize that “adaptive leaders who are comfortable operating in ambiguity and complexity will increasingly be our competitive advantage against future threats to our Nation” (Elliott et al. 2013, 30). Only time will tell whether this interdisciplinary rubric has met its goal of creating a grading mechanism that can be used in multiple project mediums across multiple disciplines. Given the extensive research and analysis done at West Point to create this much- needed and useful tool, the prospects for future interdisciplinary education are promising.

A Report on Community Colleges and Science and Civic Engagement in Asia: A Yearlong and Continuing Journey

 

Throughout 2013 I had the opportunity to travel to East and South Asia, to explore connections between the work of community colleges and civically engaged science. What follows is a general summary of what was learned through a combination of ethnographic observation and ongoing scholarly engagement with Sias University in China, the Asia Pacific Higher Education Research Program (APHERP) at the East-West Center in Hawai’i, and the University of Mumbai in India. The report will conclude by suggesting how these international interactions relate to a new Teagle Foundation-funded project at Kapi’olani Community College and the Community College National Center for Community Engagement (CCNCCE).

International Water Conference at Sias University, Henan Province, China

Sias University is the first solely American-owned university in Central China, affiliated with both Zhengzhou University and Fort Hays State University, Kansas. It is located in Henan Province, which was the center of a rising Chinese civilization nearly 5,000 years ago. Today, more than 100 million people live in Henan, which is two-thirds the size of Arizona. Although the Yellow River does not flow through Henan Province as it once did, the river skirts the boundaries of the Sias campus.

Dr. Paul Elsner, who for 22 years served as Chancellor of the 10-campus Maricopa Community College System, invited me to make a presentation at the Sias University International Water Conference, May 22–25, 2013. Dr. Elsner knew that Kapi’olani Community College (KCC) and the University of Hawai’i at Manoa (UHM) had developed and sustained a strong service learning and civic engagement program called Malama i na Ahupua’a (to care for the ahupua’a), which engages students and faculty in restoring ancient Hawaiian watersheds throughout the island of O’ahu.

He knew about “Kapi’olani Sustainability and Service Learning” (KSSL, our new name), through our two-decades-long partnership with the CCNCCE, an organization that he founded and strongly supported as Chancellor. Dr. Elsner is currently on the Board of Sias University and saw striking similarities between water problems in Arizona and central China.

However, Dr. Elsner did not know of my earlier anthropological work in this field and its relevance to the conference topic. In 1995 I published a report for the UHM Water Resources Research Center (WRRC) entitled, “Water: Its Meaning and Management in Pre-contact Hawaii.” This paper was developed in professional collaboration with Dr. Marion Kelly, who was an advocate for Native Hawaiian people and history and founded the UHM Ethnic Studies Department. Both the report and the collaboration coincided with the development of the Malama i na Ahupua’a program.

The WRCC report was set against the controversial theory linking irrigation with “oriental despotism” that Karl A. Wittfogel presented in in Oriental Despotism: A Comparative Study of Total Power (1957). Wittfogel analyzed the role of irrigation works, the bureaucratic structures needed to maintain them, and the impact that these had on society, coining the term “hydraulic empire.” This theory has led many Western archaeologists to focus on early forms of irrigation and water management.

During the late prehistoric period in ancient Hawaii, irrigation and other water management practices supported the sociopolitical evolution of a proto-state. The report used archaeological data as a point of departure to analyze the meaning and management of water in this period. An analysis of Hawaiian chants, legends, and proverbs was woven into the archaeological data in an in an attempt to better understand the meaning of water to the indigenous people of the Hawaiian Islands. (I used similar data in deriving pre-contact Samoan perceptions of the meaning of “work” in my dissertation in 1985.) The report concluded that intra-island (windward-leeward) and inter-island (geological-hydrological) variation produced important localized meanings of water, and that these meanings changed over time, largely in relation to population growth, production, intensification, and increasing sociopolitical complexity. My own research in this area provided a useful context for my participation in the international discussions that took place during my visits.

The Sias International Water Conference brought together international and Chinese scholars. Prominent international researchers included Dr. Jonathon Overpeck, who served as a coordinating lead author for the Nobel Prize-winning UN Intergovernmental Panel on Climate Change (IPCC) Fourth Assessment (2007); Dr. Sharon Megdal, Director of the University of Arizona Water Resources Research Center; and Dr. Brian Fagan, with whom I studied archaeology at UC Santa Barbara in the early 1970s, and who is the celebrated author of The Attacking Ocean (2013), and other major world archaeology publications. Chinese researchers included: Dr. Zuo Qiting, Professor, College of Water Conservancy and Environmental Engineering, Zhengzhou University, and Director of the Water Science Research Center; Dr. Zhang Qiang, Deputy Director of Department of Water Resources and Environment, Sun Yat-Sen University; and Yao Tandong: Glaciologist at China’s Institute of Tibetan Plateau Research.

China is one of the most water-rich countries in the world, but water resources are unevenly distributed and overwhelmingly concentrated in the south and far west on the Tibetan Plain, which also serves as a major water source for India. Water scarcity has always been a problem for Northern China and has been increasingly so as a result of rapid economic development. Major water engineering projects have been completed, and more are underway, to move water from the south to the north, with significant implications for Tibet-India-China relations. Major conference topics included severe water scarcity in Northern China, water quality and severe pollution in both Northern and Southern China, rural and urban challenges, and the likely deleterious future impacts of climate change, mega-droughts, and sea level.

The conference also served as a showcase for Sias University’s innovative approaches to teaching and learning about water issues in China, such as a mesmerizing theatrical representation of water history in China, and their World Academy for the Future of Women (WAFW), which requires service projects as part of membership activities. Hundreds of students have gone through the Academy and created both short- and long-term projects of great value and impact. According to Dr. Linda Jacobsen, former Provost at Sias:

Some young women shared that they applied to study at Sias because of the exciting service projects the WAFW members were sharing at home on semester breaks. Projects include the installation of drinking water filtration systems, environmentally safe agricultural practices, communal water area clean-ups, and eliminating violence against women. Over the years, these projects, which started locally in the university community, have expanded to regions within China where the members live. (Linda Jacobsen, Provost, Paper for 2014 Continuums of Service Conference, Honolulu)

My own presentation at the Water Conference was titled, “Service-Learning: Social Responsibility and Caring for Our Water Resources.” The talk sidestepped the concept of “civic responsibility,” partly because it was implied by the name of the host institution, the incipient “Institute for Social and Environmental Responsibility,” but also because I was not sure whether the discourse on the “civic” was widely understood, or even acceptable in China. My presentation was the only one addressing sea-level rise and coastal water issues and it offered the GLISTEN project (Great Lakes Innovative Stewardship through Education Network) as a model for tackling major water issues in China. The paper was very well received (I’m sure the beautiful photos of Hawaiian ecosystems helped), and Dr. Jacobsen and I continue to dialog about future directions and partnerships.

East-West Center: Asia Pacific Higher Education Research Program (APHERP), Senior Seminar, at Hong Kong Institute for Education

In July 2013, I was invited to participate in a Senior Seminar entitled, “Research, Development and Innovation in Asian Pacific Higher Education,” September 26–28, 2013. The seminar was led by APHERP Co-Directors, Drs. Deane Neubauer (UH Emeritus) and Dr. John Hawkins (UCLA), and brought together 14 higher education researchers, administrators, and faculty from China, Taiwan, South Korea, Malysia, Thailand, Australia, Chile, and the United States. My participation constituted a follow-up to East West Center-sponsored seminars in Honolulu and Indonesia that focused on developments in Asian-Pacific Education with a view toward 2020.

Dr. Neubauer’s concept paper provided a focus for the seminar:

Research and development (R&D) have long been a key component of what has generally been called “research universities.” There is also recognition that in order to stay on the cutting edge of R&D, higher education institutions (HEIs) must increasingly strive for innovative R&D, and this has important implications for the structure and governance of higher education as well as numerous other factors of HE change and transformation. Furthermore, in a manner that may be unprecedented in the period of the so-called modern university, innovation, as almost a form of social responsibility, has been thrust upon the university. Interestingly and overwhelmingly, due to the role that the university is performing within the emergent knowledge society, innovation in the “knowledge transfer” functions of the university—the teaching role foremost among them—has become of increasingly greater importance.

I was invited to present a paper titled, “The University-Community Compact: Innovation in Community Engagement,” which focused on the evolution of the American community college and its essential functions: university transfer, workforce development, and educating for engaged citizenship. The paper discussed the central differences among three related concepts:

  • Civic engagement as the “participation of private actors in the public sphere, conducted through direct and indirect interactions of civil society organizations and citizens-at-large with government, multilateral institutions, and business establishments to influence decision making or pursue common goals” (World Bank).
  • Civic responsibility as “the active participation in the public life of a community in an informed, committed, and constructive manner, with a focus on the common good” (Robinson and Gottlieb, American Association of Community Colleges).
  • Community engagement as “the collaboration between institutions of higher education and their larger communities (local, regional/state, national, global) for the mutually beneficial exchange of knowledge and resources in a context of partnership and reciprocity” (Carnegie Foundation Community Engagement website).

Significantly, all three definitions skirt the discourse on democracy, which was advantageous in this context as I was uncertain about the advisability of discussing democracy in contemporary China. The presentation also used the GLISTEN initiative as a model and explored strategies for taking civic action on major water issues in East and Southeast Asia.

Community colleges are emergent in East, Southeast, and South Asia. However, five core features of American community colleges are underdeveloped. American community colleges are

  1. Rooted in local communities, preparing local students for successful economic, social, and civic engagement in their regions;
  2. “Open door” institutions, with less rigorous entry requirements;
  3. Subsidized by states, with lower tuition rates;
  4. Focused on rigorous workforce and career development through one-year certificates, two-year degrees, and lifelong learning;
  5. Organized to prepare students to meet the requirements of rigorous baccalaureate programs.

In-depth interactions with the 14 seminar participants enabled deep and sustained discussions on these and other topics related to innovation in Asian-Pacific-American higher education. Most of the innovations discussed were not focused on the role of higher education in fostering civic engagement. They were instead focused on innovations in technology and on research and development as drivers of economic and workforce development. This was seen as higher education’s larger social responsibility.

The seminar papers are currently being considered for publication by Palgrave-Macmillan, which will be publishing a new volume onService Learning in America’s Community Colleges later this year. Kapi’olani’s contribution to that volume is entitled, “Service Learning’s Role in Achieving Institutional Outcomes” (Yao Hill, Bob Franco, Tanya Renner, Krista Hiser, and Francisco Acoba).

Developing Community Colleges with the University of Mumbai

After the Hong Kong seminar, I traveled to the University of Mumbai for the fourth stage in discussions about establishing the University of Mumbai (UM) community colleges. These discussions have largely taken place at the level of senior leadership at KCC, UH, and UM, and had contributed to a grant proposal submitted to the Obama-Singh 21st Century Knowledge Initiative, advocating the building of higher-education bridges between India and the United States, the world’s two largest democracies.

For three days in October, I participated in very full days of meetings. Major progress was made on the grant proposal, which focuses on the development of UM community colleges offering general education and training in Hospitality Management, Health Services, and Business.

India is determined to transform its future economic growth through higher education reform, seeking to expand access to quality workforce development programs as well as to improve employment prospects for India’s burgeoning youth population of 700 million. The U.S. community college model is increasingly seen as one of the key vehicles driving this reform across India, bringing a formal two-year associate degree, job-focused certifications and industry linkages, and broader community and societal impacts, particularly in spurring income growth for diverse communities and populations.

On the evening of October 2, the UM leadership graciously escorted me to the University’s glorious celebration of the birthday of Mohandas Gandhi. Earlier we had talked about Gandhi and Martin Luther King, and their roles in inspiring civil and civic action. We also discussed Martin Luther King’s role in the American civil rights movement, and the concurrent development of America’s community colleges throughout the 1960s. During the intensive three days we even developed a course outline focusing on the lives of these two men and Nelson Mandela, which would be used as part of the new general education curriculum to be implemented at the UM Community College at Ratnagiri.

Mumbai, with a population of 13 million, and Ratnagiri, with a population of 1.7 million, are located on India’s long western coast on the Arabian Sea in Maharashtra State. This coastal ecosystem supports millions of residents and attracts millions of domestic and international visitors annually. We had in-depth discussions on how to promote sustainable tourism in Maharashtra State, particularly in the context of sea-level rise, and water challenges throughout India. Again, the SENCER GLISTEN model provided a pattern for collaborative and civic action.

Throughout the rest of October I developed the partnership proposal, which has four objectives:

  • Develop a best practice University of Mumbai Community College at Ratnagiri (UMCCR) with an initial degree program in Hospitality Studies, followed by Health Studies and Business and Financial Services Programs.
  • Develop at the University of Mumbai, Kalina Campus, The Center for Excellence in Community College Leadership, Teaching, Research, and Development (COE).
  • Develop articulated degree pathways linking UMCCR, UM, and KCC and UH, initially in Hospitality Studies, and then in Health Studies and Business and Financial Services.
  • Develop university-private-civil sector partnership agreements to support the UM-KCC-UH collaboration now and into the future.

Conclusion

Fresh water-saltwater convergences, and water availability and quality, are major global issues that affect the United States and East, Southeast, and South Asia. Higher education systems in all these areas are conducting research that informs public policy development. Meanwhile these problems are intensifying at an exponential pace. Our colleges and universities need to research, educate, and partner with non-profit organizations, and with local, state, and federal agencies to reduce the severity of the impact of water issues. The community colleges are well situated to do this work in close collaboration and authentic partnership with transfer universities that share the same ecosystems.

In January, 2014, KCC and CCNCCE received a three-year $270,000 grant from the Teagle Foundation titled “Student Learning for Civic Capacity: Stimulating Moral, Ethical, and Civic Engagement for Learning That Lasts.” In this project seven community colleges in six states, New York (2), New Jersey, Louisiana, Arizona, California, and Hawai’i, are integrating the following “Big Question” into first- and second-year courses: “How do we build OUR commitment to civic and moral responsibility for diverse, equitable, healthy, and sustainable communities?”

This question is the kind of capacious, contested, and civic issue that SENCER continues to emphasize in its work on the STEM curriculum. I hope to present some answers to this question, from a community college perspective, at SSI 2015. Meanwhile, I welcome discussions on this question with university colleagues through the SENCER network as it expands to include countries around the globe.

Science Bowl Academic Competitions and Perceived Benefits of Engaging Students Outside the Classroom

 

Abstract

The National Science Bowl® emphasizes a broad range of general and specific content knowledge in all areas of math and science. Over 20,00 students have chosen to enter the competition and be part of a team, and they have enjoyed the benefits of their achievements in the extracurricular Science Bowl experience. An important question to ask, in light of the effort it takes to organize and participate in regional or national science competitions, is whether the event makes a difference to the student. And if it does make a difference, does it improve student learning or student attitudes about science? In a preliminary survey, students competing in a Regional Science Bowl Competition report that the event has a positive impact and fosters learning in science and mathematics. These data support findings for other forms of extracurricular academic competitions associated with science and mathematics.

Introduction

Since 1991, the Department of Energy’s (DOE) National Science Bowl® has been sponsoring annual regional and national competitions for high school students across the United States of America, including Puerto Rico and the U.S. Virgin Islands. In addition to seeing the pragmatic value of increasing the “feed” of science-educated personnel into DOE research facilities, the DOE recognized that the improvement of science education, broadly, would be of great benefit to the nation. Expanding its focus beyond formal science education at the college level, the DOE started the Science Bowl program to encourage high school student participation and interest in math and science. The idea was to increase science literacy in general and to encourage science- and mathematics-related careers specifically. The success of the high school competitions resulted in the expansion of the program to include middle schools in 2002.

The competitions feature teams of four to five students answering multiple choice and short answer questions in the areas of science, mathematics, energy, and technology. There are currently 67 regional high school and 36 middle school competitions. The high school competitions involve more than 15,000 students and the middle school contests more than 6,000. The winning team from each regional event is invited to Washington D.C. to compete with other winners.

Participation in Science Bowl involves working as a team, and a team’s level of success is determined not only by scientific knowledge, but also by teamwork and gamesmanship. The students’ engagement in group work directly benefits the individual team members, their social groups, and society as a whole (Greif and Ephross 2011, 6). The actual team formation and function is itself a model for both future community engagement and civic activism. In fact, creating teams is one of the three principal strategies for successfully placing students in service-learning opportunities within communities. (Harris 2009).

The National Science Bowl® emphasizes a broad range of general and specific content knowledge in all areas of math and science. Science Bowl experiences are independent of the classroom environment and generally occur because the students have volunteered to enter the competition and become part of a team. Each team must have a coach, who can be a parent or other interested person, but is usually a high school science teacher. The volunteer aspect of the competition as an extracurricular activity means that it is similar to robotics competitions, the Science Olympiad, and other interdisciplinary, multi-disciplinary, and applied endeavors. All of these programs stress the collaborative and communal nature of the projects over the content, a characteristic shared by other civic engagement and volunteer endeavors (Jacoby and Ehrlich, 2009).

An important question to ask in light of the effort it takes to run regional or national science competitions is whether the event makes a difference to the student. And if it does make a difference, does it improve student learning or student attitudes about science? The literature on science competitions is not extensive. Abernathy and Vineyard (2001, 274) asked students who competed in the Science Olympiad why they did so. The number one reason for participating in the Olympiad was that it was fun. The number two reason was that the participants enjoyed learning new things. These findings held for both male and female participants; they seemed to think learning science and math in this context was enjoyable. Abernathy and Vineyard suggested that competitive events “may be tapping into students’ natural curiosity and providing a new context for them to learn in, without rigid curriculum or grading constraints (2001, 274).”

Competitive events such as the National Science Bowl® may provide the “initial motivation” and catalyst for helping students to discover the joy of learning (Ozturk and Debelak, 2008). Academic competitions can provide motivation for students to study, learn new material, and reinforce previously learned material so that they will be ready to compete (and collaborate) with their peers from other schools both regionally and nationally—not just in games but also in academic and work environments. This type of motivation is difficult to provide in a normal classroom environment. While it can be argued that this is solely extrinsic motivation and that students should not be dependent on it, it can nevertheless serve as the spark that ignites a discovery of the joy of learning science and math.

One of the more important effective benefits of competitions like the National Science Bowl®, is that the participants, who may be the academic elite at their home schools (big fish in a little pond), must test their knowledge and skills against the students from other schools who will be their peers once they get to college and the workplace. Ozturk and Debelak (2008) note that students “learn to respect the quality of work by other children and to accurately assess their own performance in light of the performance of their intellectual peers. They achieve an accurate assessment of where their level of performance stands in the world of their intellectual capacity and, in turn, develop a more wholesome self-concept” (51) . Developing a more accurate and grounded self-concept is an important stage for children to go through on their way to becoming healthy and mature adults. This realistic and comparative self-assessment can be difficult to foster in the case of elite students who have never faced stiff competition or external challenges to their academic abilities in their home institution.

Students in academic competitions also benefit from learning not only how to succeed, but how to accept failure, learn from it, and, “subsequently, grow as a person and improve in performance” (Ozturk and Debelak 2008, 52). This, again, may be one of the most important aspects of intramural academic competitions, one that cannot be easily provided in a typical classroom environment; learning to fail and being able to cope with the emotional aftermath may be riskier in a classroom environment than in a games environment where the experience of failure is shared among the group. Being thrust into a situation where participants must deal with failure (even after they have prepared and done their best) promotes the healthy development of a student’s resilience and self-awareness. Academic competitions like the National Science Bowl® and its many regional competitions may provide the type of environment that helps students to reflect on their knowledge and abilities and self-evaluate their performance, promoting improved personal growth and development for the participants.

Certainly, extreme competitiveness can cause anxiety and undue stress (see for example Davis and Rimm, 2004). Many of us can remember learning in our Psychology 101 course about test anxiety and how it can negatively affect student performance and achievement and lead to low self-esteem. But Davis and Rimm also report that competition can increase student productivity and achievement. Some students seem to need to compete with others in order to push themselves to produce at a higher level. It would follow that socially organized competitions like the National Science Bowl® and its many regional competitions could help to promote high levels of achievement and productivity in the participating math and science students. Some of the increased levels of achievement and productivity may be due to the practice in teamwork and study skills promoted by participation in this type of academic competition. Bishop and Walters (2007) report that the students involved in competition increased their ability to be leaders and team players, especially in the areas of directed studying (“cramming”), communication, and stress management.

Most studies of this nature tend to be based on student reporting of their own perceptions, and Bishop and Walters also discuss the viability of using a self-report, Likert scale survey to investigate how the National Ocean Sciences Bowl (NOSB) influenced the participants’ choice of major and courses in college. They further triangulate their data using follow-up interviews, information on the colleges the students attended, and lists of the college courses the students took following their participation in the NOSB. Their longitudinal study, which took place from 2000–2007, establishes the credibility of the students’ self-reported data using this type of survey (Bishop and Walters 2007).

What Do the Students Get from This Competition?

A brief survey was developed for the students who compete in the Northern New England Regional Science Bowl Competition, for the purpose of gathering information about the students’ perception of the impact the competition has on them and other students. The questions were developed by the Regional Science Bowl coordinators and distributed to the students (also to coaches, volunteers, and audience) on the actual day of the competition, which takes place each year in late February or early March. The students in the Northern New England Regional Science Bowl Competition come from the three northernmost New England states, Maine, Vermont, and New Hampshire. The competition is an extracurricular activity; the students in grades 9–12 have self-selected to be part of a team that practices and competes during non-school hours. The students making up the teams tend to be academically successful. As might be expected, these students usually like mathematics and science and are predisposed to participate in activities involving these subjects. The teams of students compete in a one-day event at the University of Southern Maine, which culminates in a single elimination tournament round. The winning team is offered an all-expenses-paid trip to Washington D.C. to compete with other regional winners for the national championship. Students at the regional bowl are given the survey. Completing and returning the survey is voluntary, although the students and coaches are made aware that their responses will help improve the event.

The Instrument

The first part of the survey was designed to collect general background information about the students and their role in the day’s competition. This section was a simple checklist:

  • This is my first experience.
  • I’ve been at previous science bowls here.
  • I was a volunteer today.
  • I am a spectator/guest.
  • I was one of the student competitors today.
  • I am a coach of one of the teams.

The next set of items was intended to gain insight into the students’ perceptions of how the regional competition affected the students who were taking part in the day’s activities and events. The questions consisted of three Likert-type response choice items:

1. I think this competition had a positive impact on the students:

2. Quiz competitions foster student learning about science and mathematics:

3. Quiz competitions are stressful in a negative way:

Each of these questions had a five-choice scale that ranged from strongly agree to neutral to strongly disagree. There were also two open ended questions:

The thing I enjoyed most about today was:

What I would recommend for next year:

And finally a yes/no question:

I’d like to come back next year.

Findings and Discussion

Data collection began with the 2004 Northern New England Regional Science Bowl Competition and continued through 2009. (After this year the Bowl was restructured and focused exclusively on Maine students, although participants continue to be surveyed.) This six-year longitudinal study has provided data representing a constant mix of new and returning students. Throughout the course of the study, there was an almost equal distribution of first-time and returning students who responded to the survey. Although the survey was distributed to students, coaches, and other volunteers who took part in the events, only the results of the student surveys were used as part of this report. The voluntary nature of conducting the study produced an average of fifteen percent of the students per year completing and returning the survey. Interviews with coaches and students indicate that the low response rate is most likely a result of its collection at the end of a long, intense day, when many teams were eager to start their journeys back to homes throughout northern New England.

Of the students participating in the Northern New England Science Bowl who responded to the survey during the study period, 93 percent either agreed or strongly agreed that the competition had a positive impact on them (Table 1).

Campbell and Walberg (2011) suggest that this type of positive impact follows the students throughout their life. Willingness to participate in events on their own time, especially during the weekend, demonstrates a high level of positive engagement that would foster feelings of positive impact. Akey (2006,16) reports that “student engagement and perceived academic competence had a significant positive influence.” on achievement. The survey results also suggest that the students perceive themselves as academically competent in math and science, and that is why they participate. This mirrors the findings of Abernathy and Vineyard (2001) who report that academic competitions tap into the natural curiosity and inclinations of students and provide an arena for them to learn new things. The science bowl event could provide the platform for these students to excel and receive recognition. Further, Ozturk and Debelak (2008) report that academic competitions may provide the motivation to find the joy in learning. Curiosity and motivation are important aspects of learning that would presumably have a positive impact on the lives of the participants in academic competitions like the National Science Bowl®.

Most (91 percent) of the respondents reported either that they agreed or that they strongly agreed that the Regional Science Bowl Competition fosters student learning in science and mathematics (Table 2).

These data again appear to support the research done by Abernathy and Vineyard (2001), indicating that academic competitions provide a forum to stimulate the students’ natural curiosity about learning new things, as well as the work of Ozturk and Debelak (2008), who have concluded that academic competitions may motivate students to discover the joy of learning.

The high positive response rate of these two questions indicates that the student participants in the Regional Science Bowl Competition are developing a strong positive sense of self. These responses, reinforced by our interviews of participating coaches, indicate that the students are reflecting on their experiences and developing a more complete self-image and perhaps an increased sense of their personal competence. Bishop and Walters report that an enhanced and comparative sense of personal competence or capability “translates as a very high factor influencing career choice” (2007, 69). It may well be that academic competitions such as the National Science Bowl® and its associated regional competitions provide experiences that positively influence student career choices.

Interestingly, the same students who reported that the Science Bowl Competition had such a positive effect on them in general, and a positive effect on their learning, did not necessarily think the competition was unstressful. Only 61 percent disagreed or strongly disagreed that the quiz competition was stressful in a negative way (Table 3).

Perhaps the wording of the question led students to equate “quiz” with “test,” which affected their response. It could also be that the students consider any kind of stress negative, and if they perceived that the competition created even a low level of stress, they would conclude that this was a negative effect.

In the open-ended question that asked what they enjoyed the most about the Science Bowl, the number one response was competition, the second most frequent response was meeting like-minded people, and the third was the hands-on nature of the activities. These students seem to be saying that they feel that testing their knowledge and skills in science and mathematics against other students of similar ability is fun! Maybe this is because they are beginning to form a deeper understanding of and respect for the quality of their work, as suggested by Ozturk and Debelak (2008). Academic competitions (such as the Science Bowl) may give students the opportunity to compete mentally the way athletic competitions allow them to compete physically (Parker 1998). Perhaps these students get the same kind of “high” that athletes get during competition, and the thrill of academic competition releases endorphins much the same way that athletic competition does.

The data indicate that a statistically significant portion of the students competing in the Northern New England Regional Science Bowl Competition report that the event has a positive impact on them and fosters learning in science and mathematics. These data support findings that have been reported for other forms of academic competitions that are involved with science and mathematics (e.g. Campbell and Walberg 2011). Self-reporting indicates that the students have a high level of perceived personal competence, a high level of engagement in mathematics and science activities, and a high level of motivation toward these academic subjects. In addition to increased involvement in the community, competence, engagement, and motivation are factors that have been linked to academic achievement, personal growth, and career choices. If the education community is seeking to increase student interest and participation in science and mathematics majors and in science and mathematics careers, and ultimately in complex science-related public policy discussions, then academic competitions like the National Science Bowl® may be an important part of the overall strategy bringing the nation closer to that goal.

A Proposal for Further Study

A key aspect of the Science Bowl competition is its role in building a social community of contestants, which leads one to wonder whether the competitions contribute to increased involvement in the larger community and whether they encourage participants to become more effective and engaged citizens. Participating schools are likely to return to the event, as are alumni who come back as volunteer officials. Further, with the release of recent studies, such as “Steady as She Goes? Three Generations of Students through the Science and Engineering Pipeline” (Lowell et al., 2009), we (the authors of this paper) feel an ethical responsibility to continue the investigation of whether science competitions represent meaningful contributions to the experience of students and their disposition towards science.

To better understand the impact of the Science Bowls on both STEM learning and civic engagement, we recommend that surveys be administered for all the National Science Bowl® middle school and high school competitions. The surveys should be standardized, with optional regionally based questions, and should be part of a well-designed study that can inform future science bowl decisions. An existing instrument, the Student Assessment of Learning Gains (SALG, http://www.salgsite.org/), has survey questions that are geared towards formal academic courses but are a no-cost, accessible means to obtain data on students’ attitudes about science. Social media also provides opportunities for assessment and self-reporting of students. Surveys can be followed up by focus group interviews that could provide greater depth to our understanding of the findings. Such longitudinal studies could serve to verify whether or not these informal and volunteer learning experiences correlate with continued interest and involvement in science and mathematics, including choice of college majors, careers, and enhanced awareness and involvement in our most pressing science-related civic challenges, including climate change, public health, and technology.

Citizen Science and Our Democracy

The theme for the National Center for Science and Civic Engagement’s 2009 Washington Symposium and Capitol Hill Poster Session was “citizen science.” The term usually describes the observation and data gathering activities of ordinary people, often working from or near home, and assisting a research scientist or team in a project. We were interested in a slightly different meaning of the term, however — one that would invoke scientific literacy and numeracy as essential capacities for citizens conscientiously engaged in a modern democracy.[more]

We asked: What do we really need beyond a basic understanding of the scientific method, or discrete mathematics, or elementary statistics, to make sense of the complex civic questions we face today and will face in the future? More fundamentally, though, we wanted to explore what scientific practices and democratic practices have in common. How are the two “projects” related? And what should we do to encourage each to reinforce and strengthen the other?

For help in thinking about this, we turned to one of the handful of citizen scientists currently serving as a member of Congress, Representative Rush Holt of New Jersey. A thoughtful public servant who formerly worked in the Plasma Physics Laboratory at Princeton University, Holt graced our meeting with an original, nuanced, and encouraging address. He reminded us of the common roots of science and democracy in the Enlightenment. He reviewed the critical role that science played in what I have elsewhere called “the making of our democracy.” Echoing C.P. Snow’s critique of more than 50 years ago, he lamented the separation of the scientific and non-scientific communities into “two cultures.” Lastly, he suggested how we might begin to bridge these gaps.

We asked Mr. Holt for permission to transcribe his remarks and to include them in this issue. The man whose campaign bumper stickers playfully assert, “My Congressman IS a Rocket Scientist,” kindly assented and we are pleased to present his thoughts to you.

Representative Holt’s Remarks

[image 20249 left border]I’m really pleased to recognize the role of Rutgers in sowing the seeds for this SENCER program. It is, I think, tremendously important. I’m delighted to see you, and to see your posters, and to hear about the programs at the various universities, and to run into some old friends like Will Dorland from Maryland, who was at the Plasma Physics Laboratory when I was assistant director there at Princeton.

This is almost to the day the 50th anniversary of C.P. Snow’s address on “!e Two Cultures.” Snow’s was an interesting observation at that time, but the cultural divide Snow described has turned into, at least in this country — and I would venture to say in other countries — a critical problem that, I think, puts us at risk in a number of ways as a society. C.P. Snow, a chemist, government advisor, novelist, and otherwise diversely oriented person was talking about England 50 years ago. But his analysis applied equally well to the United States, because at the same time we launched — and “launched” is the right word following the launch of Sputnik — into an education program in the United States that really did divide our society into the two cultures of scientists and non-scientists. !is divide persists to this day.

Following Sputnik, we set in place an educational system that was intended to produce a generation of scientists and engineers the likes of whom the world had never seen. Our initial motivation was fear and our justification was national defense. And indeed, we have produced generation after generation of the world’s best scientists and engineers.

However, we have relegated them, or allowed them to relegate themselves, to a compartment of our society, of our economy, and of our political world, and we have relegated everyone else to the extra-scientific area. !at’s dangerous. So it was music to my ears, really, when President Obama, in his inaugural address this year said, “We will restore science to its rightful place.”

Now, he made this promise in a section of his address dealing with the economy. And of course, the theme of his inaugural address was, “We’re in deep trouble, economically.”

The President was making the point that investment in science is important for us to be able to grow out of our economic problems.

But that statement — that we will restore science to its rightful place — is much richer than to say that science produces jobs. Of course, science does produce jobs, which it does, even in the short term. !at is why it’s great that there is a lot of money for science in the economic stimulus bill that was passed by Congress and signed by the president. It provides $22 billion of new research money.

But the president was saying a lot more than that science creates jobs in the short term. He was also saying that science creates jobs, productivity, and economic sustenance in

the long-term. And he was saying quite a bit more than that, when he said we will restore science to its rightful place. He said that we will do away with the kinds of censorship and stifling of science — ideological stifling of science — that has undermined a basic principal of the United States. The United States has had, over the centuries, really until roughly fifty years ago, a very scientific bend. It was not a coincidence that the guys — and they were guys, sorry to say — who wrote the Constitution called themselves in many cases, “natural philosophers.” Back then, that was the equivalent of our word scientist today.

The founders were thinking like scientists; they were asking questions so they could be answered empirically and verifiably. That’s what science is. It is a system for asking questions so you can answer those questions empirically and in a way that others can verify your empirical tests for those answers.

Every shopkeeper, every farmer, every factory owner throughout American history has had this scientific tradition. It was common for Americans to think about how things work and how they could be made better and made to work better.

We’re at a time now where, if I talk to most of my colleagues in Congress, most of your colleagues at the college or university, or any American on the street, however well educated, however able, however smart, they will likely say, “Oh, science, oh no, I’m not a scientist. I can’t understand that, that’s not for me.”

And thus we are deprived of the scientific way of thinking. The scientific way of thinking is important not just for developing new technologies, but for creating the kind of self-critical, self-correcting, evolving society we need to create. The whole balance of powers in our constitution, the whole idea of openness that we embrace as a democracy, these are very scientific in nature.

It is so important that we try to bridge this chasm, merge these two cultures, so that no educated person in America would ever say, “Oh, that’s science, I can’t think about that.”

Your courses are so good because you work at from both directions. Much of my career has been as a teacher, and any teacher will tell you, the first challenge is motivation. You know, there is nothing you can teach. That’s the dirty little secret that faculty members sometimes learn. You can only help students learn.

Students have to have some reason to do the work, a purpose for learning the material. You provide that purpose in many cases by reminding them that learning has to do with the quality of their life in areas that they may never have thought had anything to do with science. You have shown them that they don’t have to wear lab coats or do equations in order to bring a scientific understanding, and more important, a scientific frame of mind, a kind of questioning attitude, to their lives, their work, and their roles as citizens.

Looking for empirical answers and independent verifications is essential to help find the answers to the important questions in daily life, whether it’s trying to decide what kind of soap to buy, or what kind of college to attend, or what kind of candidate to vote for. In what you do in your courses I see an attempt to provide for students that very kind of motivation.

But you also are working at it from the other end, nudging the scientists to move out of their culture. You are helping scientists understand that non-science students at the university — and the 80 percent of the American population who say science is not for them — are not just a necessary nuisance in their lives, but really the whole reason that we practice science.

Why do we practice science? So that we can have a better quality of life, so that we can understand how the world works, get along with each other, and provide for the needs, and not just material needs, the needs of the people and society. You know, I’d like to say that President Obama thinks like a scientist. He might dispute that, but I see it in how he conducts meetings. I see how he asks questions in a way that they can be answered empirically with evidence. He asks questions with an open mind, recognizing that the answer to the question must necessarily be regarded as provisional. You know every scientist — every physicist anyway — has somewhere in the back of his mind or her mind that whatever it is you think about how the world works, how this subject works, what is known about plasma physics or planetary science, is provisional. !ere might just be a patent clerk in Switzerland who has a little different idea or maybe even a very different idea. And empirically, some day that patent clerk’s ideas might supersede everything you thought you knew.

It is this kind of thinking that has made science so successful. Science gives a kind of reliable knowledge, provisional though it may be, that allows people to improve their lives.

It is this kind of thinking that allows citizens to improve their government. It is why we are the oldest surviving constitutional government in the world, because the authors were thinking like scientists, and they set up a system that allowed us to keep thinking like scientists.

Every business major and English composition major that you bring in to your classes is not just someone who can have the beauties of science unlocked for them in a small way. It may be that this student will be the citizen who will help move our society along through scientific thinking.

You are doing a favor for each faculty member you nudge out of her or his narrow specialty to be exposed to the great unwashed non-science student body. You are doing a great favor by reminding them their science is all about. They’re not doing science for their own esoteric entertainment. A few might be, but that is not why the National Science Foundation puts out billions of dollars a year. That is not why this Congress is interested in science. We are interested and making investments because of what this means for our society and the welfare of all of these people who are in this nation conceived in liberty and dedicated the proposition, that all, not just those who did differential equations, or you know, spectrophotometry, are equal, and deserve the benefits of our society.

So what you are doing is the missing link between things that the NSF, and the NIH, and NIST and others have funded for years. And what all the rest, the 80 percent non-scientific society have not only been deprived of, but have ignored for all these half-century, roughly speaking.

So thanks for doing what you do. I hope you understand the importance of what you are doing. I certainly do. And I thank you very much.

Emerging Topics in the Study of Life on Earth: Systems Approaches to Biological and Cultural Diversity

There is broad consensus in the international scientific community that the world is facing a biodiversity crisis — the accelerated loss of life on Earth brought about by human activity. Threats to biodiversity have been variously classified by different authors (Diamond 1989, Laverty and Sterling 2004, Brook et al. 2008), but typically include ecosystem loss and fragmentation, unsustainable use, invasive species, pollution, and climate change. Across the globe, traditional and indigenous cultures are affected by many of the same threats affecting biological diversity, including the unsustainable use of natural resources, changes in traditional land use, and cultural assimilation. [more] Academics and practitioners alike agree that to stem the erosion of biological and cultural diversity, we need to engage theoretical and applied perspectives from the natural sciences, social sciences, and humanities. In addition, we need to approach biological and cultural diversity from an integrated, systems-based perspective that emphasizes interconnections and interactions — and teach our students to do the same (Huggett 1993, Richmond 1993, Ford 1999, Sterman 2000, Richmond 2001, Kunsch et al. 2007, Nguyen et al. 2009). Fortunately, in our experience as scientists, social scientists, and teachers, sustaining diversity is a topic that interests students and can easily transcend and tie together diverse fields beyond biology, from statistics to law, from medicine to public policy. In this review, we highlight emerging topics related to sustaining biological and cultural diversity that are amenable to a systems-based approach. In the final section, we offer brief notes on active, student-engaged tools and approaches through which these topics can be taught to increase understanding of systems-based approaches by students.

Humans depend upon biodiversity in obvious as well as subtle ways: we need biodiversity to satisfy basic needs such as food and medicine, and to enrich our lives culturally or spiritually (Krupnick and Jolly 2002, Weladjii and Holand 2003, MEA 2005, West 2005, Losey and Vaughan 2006, Lambden et al. 2007, Ridder 2007). Yet in an increasingly technological world, people often forget how fundamental biodiversity is to daily life. When we hear about species going extinct or ecosystems being degraded, we assume that other species or ecosystems are around to take their place, or that in the end it does not really affect us. We rarely feel individually responsible for the loss of biodiversity, although human activities are the leading threat to the Earth’s biodiversity. Immersed in our managed environments and virtual worlds, surrounded by houses and offices, streets and shopping malls, our direct contact with “nature” often consists of aquaria in our living rooms or manicured parks to which we drive in private automobiles. In many places it is hard to remember that food in the grocery store did not spring forth packaged, ready to cook and serve. Yet if we were to put a bubble over the managed environments of our cities and towns and tried to survive with no input from the natural world, we would quickly perish — humans are part of the natural system.

Simultaneously, at a time when the environmental and social consequences of human-induced changes such as deforestation, desertification, degradation and reduction of global water resources, and climate change are increasingly severe (MEA 2005), we are witnessing a homogenization of human cultures, livelihoods, and languages. In response, we need to broaden our traditional definition of what constitutes valid scientific data or “evidence,” and appreciate and learn from the vast variety of approaches to human-environment relationships that have developed across the world’s diverse cultures and languages, often through close interactions with the natural environment and based on a perception of humans as part of, rather than separate from, nature. The humanities, including history, philosophy, and the arts, play critical roles in exploring these issues. For example, cross-disciplinary scholarship has illuminated the critical intersections between art, science, and the environment in a broader cultural context (Blandy et al. 1998, Lambert and Khosla 2000, Thornes 2008). As global citizens, we need to re-examine and redefine the place of humans as part of life on earth, and to achieve a clearer understanding of the interconnections among biological, cultural, and linguistic diversity.

To achieve this vision, students need to be able to understand issues and challenges from an integrated, systems-based perspective; one way to achieve this goal is by teaching with active, systems-based techniques (Bosch et al. 2007, Westra et al. 2007, Mahon et al. 2008). In the classroom, teachers can use case-based examples that illustrate causal chains and attenuating or reinforcing feedback interactions. For example, students working through a case study of a fishery as a complex system would discover that the system extends from the resource base and its supporting ecosystem through harvesting and distribution to the consumer, whether local or as a buyer in the global marketplace. In addition, students could identify disparate factors affecting the fishery, such as shifts in climate regime, rise or fall in energy costs, and government policies to protect or exploit a resource, and explore how their interactions can determine the collapse or the long-term sustainability of the fishery. Students may also consider the history of the fishery and the culture of the fishing community, a lesson that can reinforce the importance of understanding baselines and viewing cases from a historical perspective (Jackson et al 2001). Such an exercise reveals the system to be diverse, dynamic, and complex, and demonstrates that effective governance must recognize the interconnections and adaptive capacity of the fishery.

In this essay, we highlight several emerging topics in the study of cultural and biological diversity that could be used to develop systems-based skills in students, and then discuss specific implementation strategies for teaching these topics. Notwithstanding the contribution of the humanities disciplines to some of these topics, given our own disciplinary backgrounds, we focus on contributions from the natural and social sciences. We begin with two topics that illustrate the importance of biodiversity to humans (ecosystem services and ecosystem resilience), and then move on to consider climate change, human health, and cultural diversity. We continue with sections on community based conservation and engaging the public, and conclude with a discussion of how these topics can be taught in order to foster systems-based thinking in students.

Biodiversity and Ecosystem Services

An ecosystem is comprised of all the organisms that live in a particular place, and their abiotic (non-living) environment. The outcomes of interactions between organisms and the physical environment include complex processes, such as nutrient cycling, soil development, and water budgeting, which are all considered ecosystem functions. When these outcomes and processes are viewed in light of their benefit to humans, they are considered an ecosystem service. These services are far-ranging and include: the regulation of atmospheric gases that affect global and local climates including the air we breathe; maintenance of the hydrologic cycle; control of nutrient and energy flow, including waste decomposition, detoxification, soil renewal, nitrogen fixation, and photosynthesis; a genetic library; maintenance of reproduction, such as pollination and seed dispersal in plants we rely on for food, clothing or shelter; and control of agricultural pests. Humans can rarely completely replace these services and, if they can, it is often only at considerable cost (e.g., Costanza et al. 1997, Daily et al. 1997, Daily et al. 2000, Heal 2000, MEA 2005).

Plants and their pollinators (such as wasps, birds, bats, and bees) are increasingly threatened around the world (Buchmann and Nabhan 1995; Kremen and Ricketts 2000), yet pollination is critical to most major agricultural crops and virtually impossible to replace. In some places, a lack of pollinators has forced conversion to hand pollination (Partap and Partap 2000). There is a growing body of research that is attempting to estimate the replacement costs for natural and managed pollinators (e.g., Allsopp et al. 2004). In the Maoxian region of China, an important apple-growing region, it takes roughly 20–25 people to pollinate the apples in an orchard in one day, and costs the farmer roughly 70 US dollars. If pollination were done by rented honeybees, farmers would pay only 14 US dollars. Although the region has a long history of beekeeping, the pesticides used on the apple trees have made beekeepers unwilling to rent their bees to farmers (Partap and Partap 2000).

The relationship between biodiversity and ecosystem services is complex, and remains an active area of research (e.g., Naeem et al. 1995, Kremen 2005, Balvanera et al. 2006, Hector and Bagchi 2007, Schmitz 2009). Integral to any effort to sustain ecosystem services is an understanding of what traits and components of the system must be conserved in order for a particular service to persist. There is uncertainty regarding the ability of ecosystem services to persist in the face of reduced species diversity, and more research is needed to fully understand the importance of high levels of biodiversity on ecosystem function (Diaz et al. 2006). Despite these uncertainties, we do know the importance of individual species to ecosystem services is largely determined by the species’ functional traits, or the ways in which a species interacts with its ecosystem, rather than just the number of species present (Chapin et al. 1997, Duffy 2002, Chalcraft and Resetarits 2003, Hooper et al. 2005, Wright et al. 2006, Violle et al. 2007, Diaz et al. 2006). We also know that functional diversity (the variety of different roles played by all species in an ecosystem) in the ecosystem is an important determinant of the magnitude of the impact the loss of a species will have on the ecosystem. In some cases there are multiple species that perform the same role in keeping an ecosystem functioning; for example there could be many types of invertebrates that assist in the decomposition of leaf litter. If a high number of species perform similar tasks, the loss of one functionally redundant species is likely to have a smaller effect than if only one species could perform the task, and it is lost from the system (Chapin et al. 1997, Tilman et al. 1997).

Recent research is considering ecosystems as multi-functional systems, rather than focusing on one ecosystem process, and is striving to measure the importance of species based on their roles in supporting multiple ecosystem functions (e.g., Hector and Bagchi 2007, Gamfeldt et al. 2008, Kirwan et al. 2009). These efforts indicate that measuring the impacts of species-loss on one ecosystem service at a time may undervalue the total contribution of species diversity to ecosystem function as a whole. As a consequence, overall ecosystem function may be more susceptible to species loss than single ecosystem services are, and thus, may be more vulnerable than earlier research may have suggested (Gamfeldt et al. 2008). Clearly, an integrated, systems-based approach is needed to understand the relationship between biodiversity and ecosystem services.

An emerging strategy for conservation involves incorporating ecosystem services into economic markets by making direct payments to local actors (payment for ecosystem services, PES). One such system in Nicaragua used payment to farmers as incentive for integrating additional trees into agricultural or grazing lands (Pagiola et al. 2007). PES practices can produce on-site benefits such as improved pasture production and fruit, fuel wood, timber, and fodder production. Adding trees to an agricultural system can also have off-site benefits for ecosystem services, such as carbon sequestration and maintenance of the hydrological system, and farmers were paid for both these on-site and off-site benefits. In this case, the additional payment for off-site benefits encouraged farmers to participate; on-site gains alone were not sufficient motivation to change behavior. Monetizing the positive contribution to ecosystem services created the incentive for local actors to shift practices.

PES can have beneficial social as well as ecological outcomes, as many underdeveloped and poor areas have the potential to provide large amounts of currently un-monetized ecosystem services (Bulte et al. 2008). For example, Wunder and Alban (2008) report on a program in Ecuador, where the residents of the Pimampiro municipality pay the largely indigenous and poor owners of the upstream forests to refrain from converting forest to agricultural land in order to protect the city’s drinking water supply. PES programs must therefore evaluate the social setting in which they will be instituted, in addition to evaluating the ecological and economic costs and benefits, to determine the success of PES actions. PES supporters also have an obligation to consider the impacts of their actions on social structures and the rights of those involved (Bulte et al. 2008, Carr 2008).

Biodiversity and Ecosystem Resilience

Ecosystem resilience is the ability of a system to adapt and respond to changing environmental conditions. The relationship between biodiversity and resilience is complex and controversial (Lehman and Tilman 2000, Pfisterer and Schmid 2002), and an area of active research. Resilience theory is based on the idea that as certain thresholds are passed, long periods of gradual ecological change are punctuated by non-linear, rapid, unpredictable, and extreme shifts in ecosystem composition and function (Folke et al. 2006), an ecosystem “regime shift.” In the modern era, these sudden shifts have often been initiated by human activities, such as increased intensity of resource use, deforestation or ecosystem conversion, species introductions, or pollution. For example, Osterblom et al. (2007) suggest the Baltic Sea went through three key transitions in the last century. The first was a shift from a seal-dominated to a cod-dominated system; they conclude that this was due to a 95 percent reduction of the seal population, initially due to hunting (1900–40) and then due to pollution (1965–75). The second was a shift from an oligotrophic (low-level of primary productivity) to a eutrophic (high-level of primary productivity) state; this was mainly caused by anthropogenic nutrient loading around the 1950s. Finally, they suggest that by the 1970s the shift to a eutrophic state reduced cod numbers and, in combination with overfishing of cod, may lead to a regime shift from a cod-dominated to a clupeid-dominated system. Currently, Osterblom et al. (2007) only consider the shift from oligotrophic to eutrophic conditions as a true regime shift, meaning that it has reached a stable state and will remain eutrophic even with reduced nutrient loading. This shift will have lasting impacts on the cod fisheries of the Baltic and on the biodiversity of the region.

In general, the loss of rare species has a lower impact on ecosystem function than the loss of abundant species (Diaz et al. 2006). Some species, however, have important ecological roles despite their relatively low numbers and are called keystone species. Removal of one or several keystone species may have ecosystem-wide consequences immediately, or decades or centuries later (Jackson et al. 2001). The point at which major ecological changes, or regime shifts, will take place is highly unpredictable, but advances are being made in our ability to predict when species losses will result in these shifts. Current systems-based research continues to expand our knowledge of precursors of regime shifts, such as increased variability of state variables, or variables that determine the stable regime of an ecosystem (e.g. increasingly variable phosphorous levels before a shift to a eutrophic lake system; Carpenter and Brock 2006). This improved understanding should assist in improved ecosystem management. With advance warning, managers may be more likely to determine when efforts are needed to protect species, and when built-in redundancies are sufficient to sustain ecosystems in their current states. It is also possible that while some losses of biodiversity may not drive regime shifts directly, they can leave ecosystems more vulnerable to future changes that could have previously been absorbed (Folke et al. 2004). In the face of the biodiversity crisis, understanding resilience will be essential in directing limited conservation efforts to best protect ecosystem services.

Climate Change Effects on Biodiversity

As mentioned above, climate change as a threat to biodiversity has received increasing levels of attention in recent years. In February 2007 the Intergovernmental Panel on Climate Change (IPCC) released its Fourth Assessment Report (IPCC 2007a). This report, with its observations of increases in global average air and ocean temperatures, widespread melting of snow and ice, rising global mean sea level, regional changes in precipitation patterns, and variations in extreme weather, provides unequivocal evidence that the Earth’s climate is changing. In this report, the IPCC (2007a) indicates that most of the observed increase in globally averaged temperatures since the mid-20th century is very likely due to the increase in human-caused, or anthropogenic, greenhouse gas concentrations. Over the next two decades, a global average warming of about 0.2°C per decade is projected for a range of emissions scenarios, and continued greenhouse gas emissions at or above current rates will cause further warming and induce many changes in the global climate system during the 21st century that will almost certainly be larger than those observed during the 20th century.

Evidence from the fossil record (Davis and Shaw 2001) demonstrates that changes in climate can have a profound influence on the myriad of species that comprise Earth’s biodiversity. Scientists expect that climate change to date and predicted change over the coming century will have a significant influence on this diversity (Berry et al. 2002, Thomas et al. 2004, Malcolm et al. 2006). These effects have been investigated in hundreds of individual studies, and several important reviews and meta-analyses, including Walther et al. (2002), Parmesan and Yohe (2003), Root et al. (2003), Lovejoy and Hannah (2005), Parmesan (2006), and Parmesan (2007). Documented effects include upslope and poleward shifts in distribution to escape rising temperatures, changes in disease risk, phenological responses such as changes in the timing of flowering and fruiting, coral bleaching, and impacts on ecosystems as a whole. Scientists, social scientists, and members of local communities are also accumulating information on present and predicted future impacts of climate change on human populations, including changes to food security, health, climate, and the physical environment. (e.g., IPCC 2001, 2007b, Patz et al. 2005, ACIA 2005, Mustonen 2005, Macchi et al. 2007, Salick and Byg 2007, Frumkin and McMichael 2008, Patz et al. 2008).

Predictions of continued rapid climate change over the coming century have prompted many attempts to estimate future impacts on biodiversity. One study estimated that, on the basis of a mid-range climate warming scenario for 2050, 15–37 percent of species in their sample of 1,103 study species would be on a trajectory toward extinction. (Thomas et al. 2004). Such predictions of extremely high extinction risk due to climate change have generated debate among scientists, politicians, and the broader general public. Uncertainties inherent in the predictions, along with debate as to how (if at all) society should manage the threat, make this a controversial topic. This is complicated by the fact that a growing body of evidence supports the idea that individual threats to biodiversity rarely occur in isolation. Threats occurring together could be additive, in that the combined effect is the sum of each. However, in some cases, threats can be synergistic, where the simultaneous action of individual threats has a greater total effect than the sum of individual effects (Brook et al. 2008). To be synergistic, threats must not only interact, but they must do so in a mutually reinforcing manner that contributes to population decline, and possibly to local extirpation and/or global extinction for one or more species. The strongest evidence for synergy among threats to biodiversity would be data that allow examining the effects of each threat separately as compared with the effects of the threats considered together. However, the number of studies taking this approach is still small, and they have usually been performed under experimental or semi-experimental conditions (e.g., Davies et al. 2004, Mora et al. 2007). To date, most published examples of synergies with climate change are projections, simulations or models. For example, investigators have suggested that climate change may be facilitating the spread of chytrid fungus that is causing amphibian extinctions in Central America (Pounds et al. 2006; Rohr et al. 2008; but see also Lips et al. [2008]).

Species have survived major climatic changes throughout their evolutionary history (Davis and Shaw 2001). However, scientists concur (IPCC 2007a) that contemporary anthropogenic climate change presents a significant threat to biodiversity. A key factor that differentiates contemporary climate change from past changes is the potential synergies with multiple other threats, in particular ecosystem loss and fragmentation. Natural systems exist today on a planet that is dominated by humans, with 40–50 percent of the ice-free land surface now transformed for human use, primarily in the form of agricultural and urban systems (Chapin et al. 2000). Climate change thus presents an important challenge for conservation efforts and human populations. The variety of possible effects of climate change across various domains, and the potential for climate change to interact with other threats to biodiversity, illustrate the need to consider climate change from a systems-based perspective.

Health and Biodiversity

Particularly when considered broadly (i.e. not just as the absence of illness but including physical, mental, and social stability, and in inclusive spatial and temporal contexts), human health depends on biodiversity. This does not mean that all components of biodiversity have a positive effect on health at all times (consider for example that parasites are part of biodiversity), but rather that ultimately the health of all species on the planet depends on our shared ecological context. Human health and well-being requires goods (i.e. benefits derived from tangible commodities) and services (such as the ecosystem services discussed above) provided by biodiversity, and can therefore be negatively affected by its loss. The linkages between biodiversity and human health have been the focus of much recent attention and intense study and have been highlighted by international bodies such as the World Health Organization as well as conservation non governmental organizations (WHO 2006, WCS 2009).

Food, medicine, and medical models are among the goods derived from biodiversity that are critical for sustaining human health. Aside from purely synthetic food products, all of the nutrients we consume are derived from a plant, fungus, or animal species. People all over the world meet their daily caloric and nutritional needs through some combination of wild and domesticated sources, many of which are currently threatened. Studies have estimated that at least 80 percent of the world’s population relies on compounds obtained mainly from plants as their primary source of health care (Fabricant and Farnsworth 2001, Kumar 2004). The importance of medicines derived from living things is not limited to the developing world: more than half of the most commonly prescribed drugs in the United States come from, are derived from, or are patterned after one or more compounds originally found in a live organism (Grifo and Chivian 1999). Finally, species belonging to many different taxa are invaluable in biomedical research and play a critical role in advancing our understanding of human anatomy, physiology, and disease.

Ecosystem services, as discussed earlier, support productive natural systems and large-scale ecological interactions such as pollination, pest control, soil creation and maintenance and nitrogen fixation, and are therefore critical for their persistence and the continued provision of the goods mentioned above. Other biodiversity mediated processes that benefit health and wellbeing include water filtration, flood regulation (Andreassian 2004), and waste removal (Nichols et al. 2008). In other cases, ecosystems can protect humans from natural disasters, such as cyclones (Das and Vincent 2009). Finally, empirical and theoretical evidence support the idea that species diversity can act as a buffer for the transmission of some infectious agents, including the Lyme spirochete, West Nile virus, and Hanta viruses (Ostfeld and Keesing 2000, Swaddle and Calos 2008, Suzán et al. 2009).

The differentiation between goods and services is a useful distinction with which to approach complex linkages among species and foster understanding and engagement in their conservation. In reality however, all goods are themselves the result of complex ecological interactions involving many species and their abiotic environments, and therefore broad, systems-level thinking is required to characterize, quantify, and conserve all these critically important benefits we obtain from biodiversity. As a consequence, the study of the relationship between health and biological diversity requires multidisciplinary collaboration, among biomedical professionals, ecologists and conservation biologists, and others. This kind of system-wide approach will augment our capacity to sustain the health of all species and conserve the biodiversity on which it ultimately depends.

Sustaining Cultural Diversity

The past two decades have witnessed an upsurge of interest in the links and synergies between linguistic, cultural, and biological diversity (Harmon 1996, 2002, Smith 2001, Toledo, 2002, Carlson and Maffi 2004, Stepp et al. 2004, Loh and Harmon 2005, Maffi 2001a, b, 2005, Cocks 2006). As previously mentioned, the world’s biodiversity and the vast and diverse pool of cultural knowledge, arts, beliefs, values, practices, and languages developed by humanity over time are under threat by many of the same human-induced forces (Maffi 2001b, Harmon 2002). These circumstances call for integrated approaches in research and action since culture and nature interact at many levels that span values and beliefs to knowledge and livelihoods. Yet, both in scientific inquiry and in the realms of policy and management, the categories of “nature” and “culture” are still often treated as distinct and unrelated entities, mirroring a common perception of humans as separate from the natural environment. This conceptual dichotomy is also reflected in, and reinforced by, the mutual isolation that has historically characterized teaching in the humanities and natural and social sciences, leading to fragmentation and limited communication or collaboration among different fields concerned with diversity and sustainability in nature and in culture (Brosius 1999, Oviedo et al. 2000, Borrini-Feyerabend et al. 2004, Maffi 2004, Brosius and Redford 2006). The resulting approaches, in both theory and practice, have generally failed to recognize the interconnectedness of natural and cultural processes and of the threats they are facing, or at least to bring cross-cutting expertise to bear on these issues. Thus, they have not succeeded in stemming the erosion of the diversity of life in all its manifestations. The persistent loss of this biocultural diversity is resulting in an ever less resilient world (Wollock 2001, Maffi 2005).

Recent years have seen the emergence of integrative disciplines that seek to better comprehend the complex interactions between culture and nature, and that work to incorporate insights from both the biological and the social sciences, as well as from humanistic inquiry, non-Western perspectives, and traditional cultural knowledge systems. These include biocultural diversity, social-ecological systems, nature-society theory, anthropology of nature, ethnobiology, ethnobotany, ethnoecology, ecological and environmental anthropology, human ecology, human geography, environmental ethics and history, ecofeminist theory/ecofeminism, historical ecology, symbolic ecology, systems ecology and political ecology, among others (Berlin 1992, Cronon 1996, Kormondy and Brown 1998, Adger 2000, Moran and Gillett-Netting 2000, Townsend 2000, Egan and Howell 2001, Maffi 2001b, 2005, 2007, Harmon 2002, Toledo 2002, Berkes and Turner 2006, Rapport 2007a, b). Recent ethnographic and archaeological research has also shown that our conceptualization of the relationship between nature and culture must include a temporal dimension as humans have interacted with environments through co-evolutionary processes for many generations (Balée 2006). For example, pre-colonial Native Americans shaped landscapes once considered to be “pristine” through periodic burning (Cronon 1983) and some areas of Amazonia have been intensively managed by indigenous people for centuries (Heckenberger et al 2007). We need to examine and understand the formation of contemporary and past cultural landscapes and patterns of biodiversity and how interactions between societies and environments change through time. Agencies, institutions, and organizations broadly responsible for environmental conservation and management, development, and cultural issues (for instance UNESCO, UNEP, Convention on Biological Diversity, and IUCN — The World Conservation Union), are expressing interest in this kind of broad, integrative work and its policy implications (UNESCO 2006). This indicates that now is the time to both assess the scientific advances in all of these integrative fields and foster their contributions to addressing the vital issues of environmental, linguistic, and social sustainability, as well as to promote communication among different ways of knowing through both scientific and traditional knowledge systems. Effective, systems-based teaching should help establish more integrated approaches to research, policy, and management in years to come.

Adger (2000) has defined social resilience as “the ability of groups or communities to cope with external stresses and disturbances as a result of social, political, and environmental change.” A group’s exposure to stress as a result of ecological change is known as social vulnerability. Social vulnerability is generally high for many indigenous and traditional peoples, who are often economically marginalized and rely directly on the natural environment for their food and livelihoods (Adger 2000, IPCC 2001, 2007b, Diffenbaugh et al. 2007, Macchi et al. 2007, Salick and Byg 2007). For these reasons, some threats to biological diversity, such as climate change and ecosystem loss and fragmentation, may be particularly acute threats to the lifeways of indigenous and traditional peoples. In particular, scientists and local communities in the northern latitudes have documented ongoing changes in their environment due to climate warming, such as reductions in sea and lake ice, loss of forest resources, changes in prey populations, and increased risk to coastal infrastructure (Lee et al. 2000, NAST 2001, CCME 2003, Weladji and Holand 2003, ACIA 2005, Ford 2007, Lambden et al. 2007). As climate change impacts arctic ecosystems, the predictive power of some traditional knowledge is reduced (Krupnick and Jolly 2002, Ford et al. 2007, Sakakibara 2008, Sakakibara 2009), which has the potential to leave societal structures weakened (Weladjii and Holand 2003, Lambden et al. 2007). It is therefore not surprising that some of the first initiatives bringing indigenous communities together to frame and address common problems related to climate change have occurred in the northern latitudes. Examples of these efforts include the compilation of the Stories of the Raven by the group Snowchange (Mustonen 2005) and the Arctic Climate Impact Assessment (2005), which was prepared by more than 300 participants from 15 countries and includes many examples of the local traditional knowledge of Inuit, Sami, Athabaskans, Gwich’in, Aleut and other Arctic Indigenous Peoples.

Community-based Conservation

From individual sacred trees to royal game preserves, strategies for conservation have historically relied on protected areas, or conserving biodiversity where it exists, in situ. Many early parks and reserves in the Western tradition of biodiversity conservation were modeled after Yellowstone National Park (established 1872) in the United States, and advocated strict preservation policies, seeking to safeguard natural resources through the exclusion of local populations (and in cases disregarding the role they had played in shaping those landscapes) (Adams and McShane 1996, Neumann 1998, 2002, Jacoby 2001, Adams 2004). By the 1970s, new ideas of sustainable development and a growing interest in human rights and different knowledge and value systems challenged this approach. Recognizing that conservation affects people’s lives (West and Brockington 2006), and that restricted access to natural resources has costs that are often borne by those least equipped to pay them (Adams et al. 2004), international conservation efforts began shifting to a more people-centered approach (Adams and Hulme 2001, Naughton-Treves et al. 2005). At the same time, the effectiveness of the protected area approach itself was in question as people realized that parks were ecological islands covering only a fraction of larger ecosystems, and management authorities frequently lacked the funds or capacity to enforce their borders. Beginning with Integrated Conservation and Development Projects (ICDPs) in the early 1990s, conservation policy began to shift from state-centric, top-down approaches to attempts to incorporate society, sustainability, and markets (Wells and Brandon 1992, Adams and Hulme 2001, Barrow and Murphree 2001). While strict reserves remain important for certain vulnerable systems, the IUCN–WCU (2009)currently recognizes six categories of protected areas of varying degrees of protection and use. Today, the mission of some protected areas has expanded to include the protection of biological and cultural diversity, the provision of economic benefits, poverty alleviation, and even promoting peace (i.e. “peace parks”, or transboundary conservation areas) (Naughton-Treves et al. 2005). Conservation efforts are increasingly recognizing the necessity of understanding the historical ecology of these protected sites and sustaining their cultural landscapes (UNESCO 2006).

“Community-based conservation” (CBC) helps conserve threatened species and critical ecosystems beyond protected area boundaries by linking natural resource protection to communities and development — in other words, by thinking of the ecosystems and inhabitants as an integrated system. Emphasizing a participatory approach to biodiversity conservation, CBC strives for a “win-win” situation where local involvement leads to economic growth and a vested interest in conservation (Adams and Hulme 2001, Berkes 2004). The case of the African elephant illustrates this logic: locally, elephants can be dangerous pests that steal crops and destroy gardens; nationally, they are major tourist attractions and the source of significant revenue. CBC seeks to expand the benefits of elephant conservation to the local level through benefit-sharing schemes or prescribing wildlife conservation as a form of land use (an alternative to agriculture or pastoralism). In this model, natural resources are recognized as renewable, opening the possibility for controlled and sustainable use. Additionally, the separation of human-dominated landscapes and “natural” landscapes is less clear, as people are explicitly included, and community perspectives and knowledge are deliberately incorporated into conservation practice.

CBC initiatives range from programs as simple as protected area or private sector outreach (e.g., Tanzania’s National Parks’ Community Conservation Service program, “Ujirani Mwema” [Bergin 2001]) to Community Conserved Areas (CCAs), terrestrial and marine spaces that have been conserved voluntarily by local communities (Kothari 2006). An important CBC model, CCAs vary widely in size and have been initiated for a number of reasons: to protect access to livelihood resources or community land tenure, for economic gain (e.g., ecotourism), or to safeguard vulnerable wildlife or ecosystem functions. They may include sacred spaces, indigenous peoples’ territories, critical wildlife habitat, resource catchment areas, or mixed landscapes (natural and agricultural ecosystems).

CBC, through innovative partnerships among conservation biologists, social scientists, and communities living in and around biodiversity hotspots, is an important complement to traditional protected areas and a vital part of the conservation toolkit. But it is not a panacea for conservation problems: for instance, the goals of biodiversity conservation and development interventions are often conflicting; communities are not homogenous entities, but represent a wide array of viewpoints and motivations, and “success” is not easily defined (see for example Agrawal and Gibson 1999, Biesbrouck 2002, Berkes 2004, Chapin 2004, Tsing et al. 2005, Rao 2006, Igoe and Croucher 2007, Nelson et al. 2007). Ultimately, however, an effective approach to biodiversity conservation will involve diverse constituencies, including international organizations, nations and national governments, non-governmental organizations, academic institutions, local grassroots groups, and individuals.

Teaching Systems Approaches to Biological and Cultural Diversity

Too often, we do not think about the interconnections in the world around us. As illustrated in the topics discussed above, change in an ecosystem can cause a chain of reactions to reverberate throughout the system, affecting the well-being of humans and other species (Diaz et al. 2006). Studies of endangered species are now pointing to the importance of coevolution, with cascading extinctions leading to the disproportionate loss in groups such as parasites and mutualists (Koh et al. 2004, Dunn et al. 2009). Researchers are also learning that synergistic interactions between different direct and indirect threats to biological and cultural diversity may amplify or exacerbate individual threats. All these interconnections are crucial for us to consider when working to sustain diversity.

As our understanding of natural ecosystems and the role of humans within them has increased, we have realized that traditional “siloed,” disassembled approaches for understanding and managing complex systems are severely limited. For instance, physical scientists study long-term trends in temperature; local communities observe changes through time in animal behavior, population abundance, and timing of reproduction; biologists study climate change and its effect on species distributions; and anthropologists study adaptation in human cultures to climate change. Rarely do these individuals come together to study the feedbacks among climate change, human adaptation, and biological responses, leading to further adaptation — yet clearly each discipline is only understanding one piece of the puzzle and cannot gain a complete picture in the absence of information from the other disciplines.

In our experience, an effective way to foster systems-based and interdisciplinary thinking in students is to combine the study of actual case studies of environmental issues (such as the fisheries case study referenced in the introduction) with active approaches to teaching. Such approaches engage students directly in the learning process, and can include a variety of activities, including interactive lectures, debates and role-playing, faculty or student-led discussions, student presentations, field exercises, and others (e.g., Bonwell and Eison 1991, Meyers and Jones 1993, Bean 1996, McNeal and D’Avanzo 1997, Silberman and Auerbach 1998, Handelsman et al. 2004, McKeachie and Svinicki 2006). There is ample evidence from the education literature that active-learning modes substantially increase student performance across many disciplines (e.g., Hake 1998, McKeachie et al. 1986, NRC 1996, Olson and Loucks-Horsley 2000), including those related to biodiversity and conservation biology (Ebert-May et al. 1997, Sundberg and Moncada 1994, Lord 1999, Ryan and Campa 2000, Burrowes and Nazario 2001, Udovic et al. 2002, Chopin 2002, Burrowes 2003). Many active teaching approaches involve students working together in small groups, and often involve an element of peer-to-peer teaching and/or collaborative learning (Slavin, 1990, Johnson et al. 2007, Barkley et al. 2004), which can foster development of the critical thinking, analysis, and synthesis skills that are important to a systems-based approach.

Each of the issues discussed in this review has its own “entry point” that can encourage students to adopt systems-based thinking:

  • Because of our universal dependence on ecosystem services and their cultural, ecological, and economic value, ecosystem services provide students with concrete and relevant examples of the importance of biodiversity conservation from the perspectives of many different disciplines. Case studies of efforts to conserve ecosystem services can expose students to the complexity of real-life conservation issues.
  • In the current politically charged public discourse around climate change and its effects, engaging students on this issue represents a significant opportunity for teachers. Indeed, this is such an important area that the Council of Environmental Deans and Directors of the National Council for Science and the Environment has established a special Climate Solutions Curriculum Committee (2009) to provide support and guidance to university teaching of climate change. Studying climate change can help students appreciate some of the difficulties and controversies that arise when scientists attempt to extend current observations to model future predictions, and understand that natural systems are composed of an interconnected network of interacting species and threats to those species.
  • As an immediate concern and a topic of personal experience for all, health is a powerful motivator for changes in behavior, and can introduce the idea of multidisciplinarity in scientific endeavors and the interrelatedness of life on the planet. For example, topics in health and the environment can be presented as medical mysteries, in which students are encouraged to discover the drivers of changes in epidemiological patterns in human or animal populations, or as choices among various interventions, using a systems-based approach.
  • The intersection between culture, biodiversity, nature, and the environment offers a rich lode for exploration with students, moving easily among philosophical and ethical realms. For example, students could discuss the issue of extinction and what it means for a species, language, or culture to disappear, given that our understanding of the world is that it is dynamic and continually evolving. Readings on resilience could explore the differences between social and ecological resilience and how those might lead to different frames within which to address the problems that we face in sustaining biological and cultural diversity.
  • The study of community-based conservation can expose students to different ways of perceiving nature as well as the suite of possible conservation interventions. For example, students might debate the relative successes of current efforts to implement CBC, such as those of Wildlife Management Areas in Tanzania (see Goldman 2003, Igoe and Croucher 2007, Nelson et al. 2007). Offering a variety of real world case studies for examination, whether across the world or in their own backyard, CBC effectively demonstrates to students the complexity of conservation decision-making and the necessity of inter-disciplinary efforts.

A variety of freely available electronic resources are available that can be used to support systems-based, active teaching in topics related to biological and cultural diversity. These include resources of the Network of Conservation Educators and Practitioners (NCEP 2009a) of the American Museum of Natural History, materials from the Ecological Society of America such as the TIEE project (2009) and the EcoEdNet repository (2009), along with appropriate materials from the National Center for Case Study Teaching in Science (2009).

Final Thoughts

Even as natural and and social scientists work to make their work with students more meaningful, we also need to move beyond the classroom and into engaging the public more directly on issues surrounding biological and cultural diversity. With current levels of public understanding of science — particularly in the United States — recognized as being deficient (National Science Board 2002, Baron 2003, Brossard et al. 2005, Bonney 2008, Cohn 2008), active involvement in the scientific process can serve to increase interest and literacy. Participants can also improve their abilities to understand and interpret what is going on around them and how it relates to their lives, and in the process take part in translating science practice into public discourse and in turn, transform it into action. Wilderman et al. (2004) suggest that participants working together can develop a sense of community ownership of data and feel empowered to use them for advocacy and decision-making. Additionally, projects that involve volunteers in the study of a species or habitat make it possible to address questions of a scope and scale that would not otherwise be possible. By working with citizen volunteers, scientists may broaden support for their projects and form a more direct link with their constituency (Greenwood 2003). Decisions based on participatory research may also be more effective and less controversial when stakeholders who have an interest in the results are involved in the process (Pilz et al. 2005, Calhoun and Morgan 2009). Similarly, stewardship groups (who may be involved in research, maintenance, and/or tours or other educational activities) can develop a strong sense of responsibility and attachment to a place that they care for, and will strive to protect it for the health of the local environment as well as for community well-being. In general, environmental volunteering and stewardship can result in a wide range of benefits for the organizations involved, the volunteers, and for the community, including extending an organization’s work and promoting its cause; giving people a chance to connect or reconnect with nature as well as gain new skills, make social connections, and improve their physical and mental well-being; and contributing to community goals for education, health, and social and environmental justice (O’Brien et al. 2008).

Programs that encourage broad public participation can also in some cases intersect with student programs. An example of this approach is ALLARM (Alliance for Aquatic Resource Monitoring), which forms partnerships between community groups and researchers and students at Dickinson College in Pennsylvania to conduct water quality monitoring and watershed management projects. ALLARM’s goals include increasing community scientific knowledge while motivating students through engaging in research to solve real-world problems (Wilderman et al. 2004). These are the overarching goals, however, and each community group defines the goals for its own project. Volunteers engage in the scientific process, from defining problems, designing the studies, collecting and analyzing samples, to interpreting data. Scientists provide training and mentoring where necessary, particularly supporting the groups through the development of a feasible study design and in interpreting data so that the community members themselves are able to understand and share their findings rather than relying on researchers to speak for them. Volunteers also have the advantage of using their local knowledge for interpretation, making connections with nearby land uses that researchers might not be aware of (Wilderman et al. 2004, Wilderman 2007).

Students of today are challenged to try to make sense of a bewildering array of information and misinformation about environmental and cultural issues. This is certainly the case with biodiversity loss and sustaining cultures. Over the past decades, we have come to understand that sustaining cultural and biological diversity does not just mean placing boundaries around a static entity. Rather, it means moving beyond the patterns we see and understanding the processes that create diversity, allowing for change and evolution while maintaining integrity of a system. Human-induced threats to biodiversity are causing not only species loss, but also are negatively impacting ecosystem processes and function and might even alter the rate of evolutionary change, which in turn can influence ecological dynamics, creating “eco-evolutionary feedbacks” (Palumbi 2001, Stockwell et al. 2003, Post and Palkovacs 2009). Though we may not have a complete understanding of the theoretical underpinnings of the interactions between ecology and evolution, it is clear that planning for biodiversity conservation needs to happen in the context of dynamic populations and threats (Mace and Purvis 2008).

In order for the next generation of adults and voters to make intelligent choices about biological and cultural diversity, they will need to understand what the consequences of their individual and collective actions are — the evolutionary force that we have become. They need to know what diversity is, to understand the relationship between human beings and diversity and how our value systems affect sustainability of biodiversity and culture (Carolan 2006, Christie et al. 2006), the difference between sustaining just patterns/static definitions of diversity rather than processes, and they need to understand what threatens diversity. Finally, students need to have a sense of what they can do about the loss of biological and cultural diversity at the individual and collective levels. Overall, they will need to take a systemic look at people and their relationship to diversity, as complex systems such as these require systems thinking for solutions (Waltner-Toews et al. 2008). As teachers, we can support them in learning to do this.

Quantifying the Atmospheric Impact of an Urban Biomass Incinerator

Abstract

This study examines the carbon footprint of a proposed biomass incinerator in Minneapolis and Saint Paul, Minnesota. This research was integrated as a service-learning project into the curriculum of an undergraduate differential equations course. Mathematical models were developed and analyzed to examine the local contribution of emissions to the atmosphere and the extent of land needed to offset incinerator emissions both in the short (daily) and long (yearly) term. [more] Our results show the sensitivity of atmospheric carbon content to the incinerator output rating, area and type of land dedicated for offsets, and atmospheric wind speed. The amount of managed land ranges from 7,000–20,000 hectares of land, or approximately the area of Saint Paul. The land requirements seem feasible in the context of the amount of available (unmanaged) land both locally and worldwide, but these requirements are diminished given the potential air quality effects resulting from biomass incineration.

Introduction

The Rock-Tenn paper recycling plant located in Saint Paul, Minnesota employs over 500 people and contributes significantly to the economic health of the greater Minneapolis-Saint Paul metropolitan area (Nelson 2007). The company initially had its thermal energy supplied by Xcel Energy, the local power provider. In late 2007, Xcel Energy decommissioned the plant that supplied Rock-Tenn’s thermal energy. Alternative sources of energy were needed to maintain the long-term sustainability of the recycling plant.

Refuse derived fuel (RDF) was a proposed alternative to provide energy for the recycling plant. This technique derives energy from the incineration of plant material, refuse, and compost (Nelson 2007). RDF is an example of bioenergy. Generally defined as the use of plant material to supply energy, bioenergy supplies 15 percent of the world’s energy needs (Lemus and Lal 2005). Bioenergy is an alternative energy to fossil fuels. Trees, through the process of photosynthesis, convert carbon dioxide into carbon, so any combustion of tree residue (and associated release to the atmosphere of this comparatively recently-fixed carbon) theoretically results in no net change of atmospheric carbon (Smith 2006).

Surrounding the Rock-Tenn plant are residential neighborhoods. In response to the proposed plan of the biomass incinerator, a grassroots organization, Neighbors Against the Burner, formed to oppose the incinerator, citing air quality effects on health (Pope et al. 2002) as one of its main objections. Based on the strong community response, in November 2008 the Saint Paul City Council passed a resolution against having the biomass incinerator be the energy source for Rock-Tenn. The Council advocated investigation of other alternative energy options, such as using biogas from anaerobic digestion (Saint Paul City Council 2008).

Augsburg College is a private, liberal arts college in Minneapolis, Minnesota, approximately three miles from the Rock-Tenn Recycling Plant. In spring semester 2008 as part of a semester-long research project for a course on differential equations, 11 students, with this author as the instructor, engaged in a service-learning project to investigate the atmospheric effects and carbon footprint of the proposed biomass incinerator. The project was integrated into the course content to provide a real-life example that had both civic and environmental connections. Two key research questions were addressed by the students:

  1. How much do incinerator emissions elevate local atmospheric carbon?
  2. What conditions need to be satisfied for carbon neutrality both short and long term?

For the purposes of this study, carbon neutrality implies zero net change in the atmospheric carbon content.

Methods

This study was integrated in the curriculum for a one-semester differential equations course. At the beginning of the term the instructor introduced the project objectives. The students formed teams to investigate the project objectives through construction and analysis of a mathematical model. The teams reported updates with the instructor throughout the semester. Additionally, a representative from Neighbors Against the Burner attended a class session to answer student questions and provide feedback. At the end of the term, students presented their results and wrote a report describing their results in the context of the mathematical, environmental, and civic dimensions of the project. The results presented in this study derive from these student projects.

Mathematical models

All mathematical models are formulated to measure the rate of change in atmospheric carbon content. Two overarching processes are assumed to affect this rate of change: emissions from the burner (increasing atmospheric carbon content) and biophysical processes that decrease atmospheric carbon. The following word equation describes this process:

Rate of change of atmospheric carbon =
Incinerator emissions – Biophysical processes

Emissions from the incinerator are assumed to occur at a constant rate, dependent on the emission type and incinerator output rating. To maintain carbon neutrality, we assume the existence of an active forest that removes carbon. With these assumptions, each team then had to quantify the appropriate mathematical model based on Equation 1. The mathematical models are qualitatively described below; additional mathematical descriptions are in the Appendix.

Emissions Contribution to Atmospheric Carbon.

Emissions from the incinerator and subsequent dispersion into the atmosphere create a plume of incinerated material and gases. This model, derived from models of contaminant transport in fluids (Brannan and Boyce 2007; Falta Nao and Basu 2005), describes the rate that incinerated carbon enters the plume. The biophysical process term is assumed to be directly proportional to the wind speed versus higher wind speed values decrease the amount of carbon near the incinerator and increase the concentration of carbon in the plume. Outputs from this model could subsequently be used to quantify spatial distribution of carbon in the plume through diffusion, advection, and other atmospheric properties.

The incinerator emissions are inversely proportional to the smokestack output area, assumed to be 250 square meters for this study. The flow (in terms of volume per time) of emissions into the smokestack must equal the flow of emissions into the atmosphere. If the area of the smokestack increases, the rate of change of atmospheric carbon must decrease to maintain the constant flow of emissions.

Short and long term carbon neutrality.

Long term atmospheric measurements of carbon dioxide over various ecosystems have shown the short and long term responses of ecosystems to carbon uptake through the dynamic processes of photosynthesis (conversion of carbon dioxide to simple sugars) and respiration (release of carbon dioxide to the atmosphere) (Baldocchi et al. 2001; Wofsy et al. 1993). Aggregated up to annual timescales, this balance between photosynthesis and respiration typically is negative (meaning the photosynthesis flux is stronger than all respiratory fluxes), indicating the ecosystem is a sink of carbon to the atmosphere. Diurnal fluctuations in temperature and moisture, seasonal variation, species composition, and plant species successional stage all contribute to an ecosystem being a given source or sink of carbon to the atmosphere (Baldocchi et al. 2001). The productivity of a forest (or its ability to decrease atmospheric carbon) can therefore be quantified with long-term records of net carbon uptake.

As previously stated, we assume the existence of a forest that will offset incinerator emissions. In our models this is represented by having the emissions term inversely proportional to the forest area. As forest area increases, emissions contribute proportionally less to atmospheric carbon because there are more trees to remove atmospheric carbon.

The biophysical process term was quantified in two different ways to describe short term (daily) and long term (yearly) carbon uptake. Short term carbon uptake was modeled with a dynamic, periodic term modeled after patterns of diurnal net ecosystem carbon exchange (Wofsy et al. 1993). Long term carbon uptake or forest productivity was assumed to occur at a constant rate, with values determined from Baldocchi et al. (2001).

Model Results of Atmospheric Carbon Content from Incinerator Emissions as a Function of Wind Speed
Figure 1. Model Results of Atmospheric Carbon Content from Incinerator Emissions as a Function of Wind Speed

Results

Figure 1 shows results of the influence of wind speed on atmospheric carbon content. As wind speed increases, local emissions decrease independent of burner output. Increasing the incinerator output rating o (measured in MBtu per hour) also increases atmospheric carbon content, inferring a higher concentration of carbon in the plume.

Figures 2a-b show model results of the daily temporal change in atmospheric carbon content. Vertical axis values in Figures 2a-b are scaled as a percent change from the initial atmospheric carbon content. Positive vertical axis values suggest that the incinerator is increasing atmospheric carbon dioxide levels, or a “carbon-positive” incinerator, whereas negative vertical axis values indicate the incinerator is “carbon-negative,” or that the forest removes additional carbon dioxide beyond incinerator emissions. The periodic behavior in atmospheric carbon results from the selection of a periodic function for the carbon uptake function (see the Appendix). Daytime has a stronger net carbon uptake, indicating trees in the forest are removing carbon from the atmosphere through photosynthesis, thereby decreasing atmospheric carbon content. As photosynthesis is a light-dependent reaction, during the night the forest is a source of atmospheric carbon.

Model Results for the Short‑Term Carbon Neutrality of the Burner
Figure 2. Model Results for the Short‑Term Carbon Neutrality of the Burner

Figure 2a reflects short term temporal emissions when the output rating of the boiler o is varied from 200 to 400 MBtu per hour. These output ratings were estimated from similar steam-producing systems as the one studied by the students (Energy Products of Idaho 2009). In all cases, it is assumed that there is an actively growing forest of 14,500 hectares (approximately the area of Saint Paul) to offset incinerator emissions. For an output rating of 400 MBtu per hour the atmospheric concentration is increasing at a constant rate of 10 percent per day, whereas for an output rating of 200 MBtu per hour the forest is large enough to reduce atmospheric carbon content by 10 percent per day.

Figure 2b shows the effect of changing the forest area on atmospheric carbon content. If the forest area is reduced to 10,000 hectares, then the incinerator becomes a source of carbon to the atmosphere with emissions growing at a rate of approximately 10 percent per day, indicating that the forest itself is not large enough to offset emissions from the plant. On the other hand, if the forest area is increased to 20,000 hectares, then the incinerator is “carbon negative,” decreasing atmospheric carbon concentrations approximately 10 percent per day.

Model Results for the Long-Term Carbon Neutrality of the Incinerator
Figure 3. Model Results for the Long-Term Carbon Neutrality of the Incinerator

Figure 3 shows the area of land that would need to be dedicated to maintain long-term carbon neutrality as a function of the output rating. As the output rating increases, a larger forest area will be needed to sustain carbon neutrality. The slope of the linear dependency in Figure 3 depends on the forest productivity (F) in removing carbon dioxide from the atmosphere. Different values of F result from the overall forest species composition (Baldocchi et al. 2001). The less productive forest (smaller values of F) will require a larger area to offset incinerator emissions.

Discussion

Evaluation of model results

A strong concern to the incinerator is the decrease in air quality in the neighborhoods surrounding the recycling plant. The results shown in Figure 1 qualitatively support this concern. Higher incinerator output ratings increase the amount of atmospheric carbon in the emissions plume. While atmospheric carbon decreases with increasing wind speed, conservation of mass infers that this carbon is dispersed to neighborhoods surrounding the incinerator.

Recent studies have shown linkages between public health and air quality (Pope et al. 2002; Zhang and Smith 2007). In addition to the carbon released through incineration, aerosols and other particulate matter may also be released into the atmosphere by incineration. While these other aerosols were not investigated in this study, the models presented here could easily be adapted to take these into consideration. Additionally, coupling this model to an atmospheric transport model could quantitatively describe increases in carbon or other aerosols and the spatial extent to neighborhoods around the incinerator.

Our results indicate that the amount of forest area needed to maintain carbon neutrality ranges between 7000–20000 hectares, depending on the type of species planted and the output rating (Figures 2 and 3). These estimates are a small fraction of land both locally and worldwide that could be dedicated to bioenergy. In Minnesota approximately 563,000 hectares of land could be rehabilitated to support bioenergy crops (Lemus and Lal 2005). Worldwide, the amount of land in need of restoration from degraded agricultural soils is approximately 1965 million hectares (Lemus and Lal 2005), which is a large proportion of the 2380 million hectares of land not classified as urbanized or protected (Read 2008). The total area of managed, or plantation, forests are 187 million hectares, consisting of 5 percent of worldwide forest area (Mead 2005).

Dedicating land to bioenergy crops helps to mitigate increasing levels of atmospheric carbon dioxide, restore soil organic carbon that were depleted from agricultural practices, and prevent erosion (Lemus and Lal 2005; Lal 2004; Sartori et al. 2006). In spite of these benefits and comparatively small area of land required to offset incinerator emissions, other factors not accounted for in our models would modify our estimates for the amount of land needed to offset emissions. First, technological advances will be required for their application, which may not be appropriate at all regional and local levels (Smith 2008). Second, bioenergy should be part of a suite of strategies targeted to mitigate climate change, which include the reduction of existing emissions through changes in consumption and improving agricultural efficiency (Smith 2008; Rhodes and Keith 2008). Third, life-cycle analyses for bioenergy crops (Adler, Del Grosso, and Parton 2007; Spartari, Zhang, and Maclean 2006) have shown a slight decrease in their mitigation potential when the growth and maintenance of the bioenergy crop (which requires energy) is taken into consideration. Additionally a recent study by Fargione et al. (Fargione et al. 2008) has quantified a substantial carbon “debt” incurred by clearing land for bioenergy crops. Further investigation into these factors is needed to refine and quantify the carbon footprint of the incinerator.

Evaluation of teaching and learning outcomes

Key learning outcomes of the project were to (a) develop and apply differential equation models to a contextual situation, (b) interpret results in the context of the carbon neutrality of the burner, and (c) provide valued recommendations based on the observations of the mathematical models.

The use of a service-learning-based project aligned well with both course learning objectives as well as the Augsburg College mission, which has a strong history in service learning (Hesser 1998). The students were given a survey to assess project outcomes in three categories: (a) overall learning (application and connection to course learning outcomes), (b) resource utilization (ability to complete the project independently), and (c) community connection (public acknowledgment of student efforts). The eleven students in the class responded to each category on a 5 point Likert scale. The average results were 3.9 (median 4) for the overall learning, 4.2 (median 4) for resource utilization, and 3.6 (median 4) for community connection. Students overall remarked positively about the service-learning project. One student remarked that “It was interesting to see real-world applications of math,” and another student commented “The project was an excellent way of learning how to put our concepts into a practical perspective, and it was also edifying to learn the nature of carbon neutrality.”

Based on the evaluations, it can be concluded from the student assessments that the first two outcomes were met (the construction, application, and interpretation of mathematical models). The lower ranking of the community connection category indicated not fully meeting the final objective. While students articulated recommendations on model results, a stronger connection to the relevant stakeholders in the issue (Neighbors Against the Burner and Rock-Tenn Recycling) could have been made. Multiple student evaluations expressed the desire for a tour of the recycling plant, or have more interaction with local community organizations beyond the mid-term visit. It would have been desirable to have a public forum of presentation of results, thereby increasing the visibility of the project in the college community.

This project has shown the qualitative contribution of the biomass incinerator to local atmospheric carbon content and the amount of land required to offset incinerator emissions. The project articulated the value of mathematical models and connected classroom learning to a civic and environmental issue.

Appendix: Description of Mathematical Models

The quantity described in all models is the atmospheric carbon density (grams carbon per square meter, or g C m-2), represented with the variable c. Models were expressed as a differential equation, and where appropriate, solved directly or with standard numerical techniques (Blanchard, Devaney, and Hall 2006). The initial condition (c0) for all models assumes a fixed CO2 mixing ratio of 385 parts per million by volume (National Oceanic and Atmospheric Administration 2009; Peters et al. 2007), assuming an air density of 44.6 mol m-3(Campbell and Norman 1998) uniformly distributed up to 21.5 m above the ground surface. Energy units are expressed in MBtu, or a million British thermal units.

Model results were investigated in the context of the following key parameters:

  1. Incinerator output rating o (MBtu hr-1),
  2. Atmospheric wind speed v (m hr-1, expressed in all figures and results as miles hr-1)
  3. Forest area A (m2, expressed in all figures and results as hectares)
  4. Forest annual net carbon uptake or productivity F
  5. (g C m-2year-1)

Emissions Contribution to Atmospheric Carbon

The model of the emissions contribution to atmospheric carbon was modified from models of contaminant transport in fluids (Brannan and Boyce 2007; Falta Nao and Basu 2005) with the following differential equation:

where c, t, o, and v are defined above, t is time (hours), α is a conversion factor from grams to pounds (453.59 grams pound-1), ε is a conversion factor to determine the amount of carbon in carbon dioxide (0.2727 g C g-1 CO2), E is the emissions fuel type for wood (assumed to be 195 lbs CO2MBtu-1 [Palmer 2008]), o is the boiler output rating, S is the incinerator total smokestack area (assumed to be 250 m2). For a circular smokestack this would be a diameter of 17.8 m, and m0 is the initial atmospheric carbon volume (0.206 g C m-3). Assuming the carbon dioxide concentration equilibrates rapidly to steady state (that is, dc/dt = 0), an expression can be determined that relates atmospheric carbon content c to the wind speed v, as shown in Figure 1 for different values of the output rating o.

Short- and Long-Term Carbon Neutrality

The short term carbon uptake was determined via the following differential equation:

where c, t, α, ε, E, and A are defined above. The periodic function represents the diurnal uptake pattern typically found in a forest (Wofsy et al. 1993). For this study, f1 = 0.1 g C m-2 hr-1, f2 = π/12 ≈ 0.262 hr-1, f3 = 0.524, and f4 = 0.05 g C m-2 hr-1. The values of f1, f2, f3, and f4, were visually determined from data of the average diurnal uptake pattern for a coniferous forest during the peak summer carbon uptake period (Monson et al. 2002; Zobitz et al. 2007).

To investigate the long-term carbon footprint, the following model was used:

where all variables are defined above. Again assuming steady state dynamics (or no change in atmospheric carbon) a linear equation between A and o can be formulated and is represented for different values of F in Figure 3.

SENCERizing Pre-service K-8 Teacher Education: The Role of Scientific Practices

 

Abstract

Recent policy reports are calling for curriculum reforms to address problems about a lack of relevance and an avoidance of the core scientific practices in science courses K–16. One important cohort is K–8 teacher candidates who need courses in which they learn core ideas in science and participate in science practices. One promising approach is infusing SENCER courses into the science course sequence for future teachers. We report a review of select SENCER courses using an Evidence-Explanation framework to assess the type and levels of science practices introduced. Results on ‘Differences in Courses’, ‘Common Themes Among Courses’, and ‘Demographic Patterns’ are reported.[more]

Introduction

Recent U.S. policy reports express a growing concern for the supply of scientists, science workers and science teachers; c.f., National Research Council 2006 report Raising Above the Gathering Storm and the National Center on Education and the Economy 2007 report Tough Choices Tough Times. The STEM (Science Technology Engineering Mathematics) teacher and workforce shortages have two components (1) declines in attracting and retaining individuals into science/science education programs of study and (2) into places of employment. These recent reports show that uptake of STEM courses and careers are waning. Then there is the documented evidence that the development of youth attitudes toward science, both negative and positive, begins in and around middle school grades (ADEEWR, 2008). Thus, much of the focus for addressing the problems is on schools and schooling K–16.

Consensus review reports (Carnegie Corporation of New York, 2009) are placing much of the blame on the curriculum models citing a lack of relevance and an avoidance of the core scientific practices that frame science as a way of knowing; e.g., critiquing and communicating evidence and explanations. The NRC K–8 science education synthesis research study Taking Science to School (Duschl, Schweingruber & Shouse, 2007) is another consensus report that makes recommendations about the reform of science curriculum, instruction and assessment. The TSTS report concludes that K–8 science education should be grounded in (1) learning and using core knowledge, (2) building and refining models and (3) participating in discourse practices that promote argumentation and explanation. The report also concludes that a very different model of teacher education must be put into place. That raises an important set of issues. Where in the undergraduate curriculum do future K–8 teachers engage in and learn to use the core knowledge, building and refining models and argumentation and explanation practices?

The typical introductory survey science courses taken by non-science majors and elementary education candidates focus more on the ‘what we know’ of science and less on the ‘how we know’ and the ‘why we believe’ dynamics and practices of science. Determining the level and degree of scientific practices in science courses is essential for shaping and understanding preservice/inservice teachers’ engagement and confidence in doing science when planning and leading science lessons in their own classroom. Science courses that focus exclusively on teaching what we know in science are inappropriate for future teachers.

Teacher candidates need courses in which they participate in science practices. One promising approach we have been considering is infusing SENCER courses into the science course sequence for future teachers (e.g., subject matter, SENCER, science teaching methods). Science Education for New Civic Engagements and Responsibilities (SENCER) course frameworks offer a potential solution to both engagement in and understanding of science practices. The SENCER commitment is to situate science learning in civic or social problems to increase relevance, engagement and achievement in science content knowledge and inquiry practices. This article reports on an analysis of a subset of SENCER courses that take up environmental problems as the civic engagement issue.

The study investigates how the design of SENCER courses provides opportunities to practice science as inquiry. The premise is that teachers gaining experience in science practices are more likely to use these practices in their own elementary school classrooms. In turn, these teachers will be in a better position to understand and hopefully address the Taking Science To School recommendation that K–8 science education be coordinated around the 4 Strands of Proficiency:

Students who understand science:

  1. Know, use and interpret scientific explanations of the natural world.
  2. Generate and evaluate scientific evidence and explanations.
  3. Understand the nature and development of scientific knowledge.
  4. Participate productively in scientific practices and discourse (Duschl et al 2007).

One of the three TSTS recommendations for teacher professional development speaks directly to the issue:

Recommendation 7: University-based science courses for teacher candidates and teachers’ ongoing opportunities to learn science in-service should mirror the opportunities they will need to provide for their students, that is, incorporating practices in all four strands and giving sustained attention to the core ideas in the discipline. The topics of study should be aligned with central topics in the K–8 curriculum so that teachers come to appreciate the development of concepts and practices that appear across all grades. (Duschl et al, 2007, p 350)

Review of Literature and Analytical Frameworks

With respect to changing how and what science is taught, one important cohort of science students is preservice elementary (K–8) teachers who have low self-efficacy when it comes to science (Watters & Ginns, 2000). The K–8 education cohort’s lack of confidence and experience within the science experiences they had contributes to maintaining a cycle in which the students they teach lose interest and confidence in learning science due to poor teaching strategies, misdirected curriculum and weak teacher knowledge. (Wenner, 1993). Sadler (2009) has found that socio-scientific issues (SSI) affect learners’ interest and motivation, content knowledge, nature of science, higher order thinking and community of practice. Thus, it is not a surprise that SENCER courses have successfully demonstrated increases in student enthusiasm (Weston, Seymour & Thiry, 2006). However, more information is needed to determine how SENCER courses impact student achievement in core knowledge of science and with science practices that involve model-building and revision. The first step toward conducting research on the impact of SENCER courses on learning is to ascertain which SENCER courses are implementing scientific practices; e.g., raising research questioning, planning measurements and observations, collecting data, deciding evidence, locating patterns and building models, and proposing explanations. The driving question is can SENCER courses when placed between science courses and science teaching methods courses effect teacher thinking and practices.

Co-designed courses represent another model that brings science and science methods courses together. The co-designed courses are planned and taught by both science and science education faculty. Zembal-Saul (2009, 687) has found that co-designed courses that adopt a framework for teaching science as argument to preservice elementary teachers served “as a powerful scaffold for preservice teachers’ developing thinking and practice . . . [as well as] attention to classroom discourse and the role of the teacher in monitoring and assessing childrens’ thinking.” Schwartz (2009) found similar positive effects on preservice teachers’ principled reasoning and practices after using an instructional framework focusing on modeling-centered inquiry coupled with using reform-based criteria from Project 2061 to analyze and modify curriculum materials. What these two studies demonstrate and the SENCER model supports is the effectiveness coherently aligned courses can have on students’ engagement and learning. Such shifts in undergraduate courses and teaching frameworks will contribute to breaking the cycle that perpetuates low interest and high anxiety in the sciences at all levels of education, K–16.

Research shows that preservice elementary school teachers tend to enter the profession with inadequate knowledge of scientific content and practice. Preservice elementary teachers answer only 50 percent of questions correctly on a General Science Test Level II (Wenner, 1993). Stevens and Wenner’s (1996) surveys of upper level undergraduate elementary education majors are consistent with other research that 43 percent of practicing teachers had completed no more than one year of science course work in college (Manning, Esler, & Baird, 1982; Eisneberg, 1977). The lack of courses and experiences in science reflected the low self-efficacy in science among preservice elementary school teachers (Stevens & Wenner, 1996; Wenner, 1993).

If no changes are made to current coursework required of preservice elementary school teachers, they will continue to have low self-efficacy in science and therefore avoid teaching this subject (Stevens & Wenner, 1996). Thus, teachers are unlikely to use inquiry within their science lessons with the result that students are not exposed to scientific practices. The cycle of negative experiences with science does not have to be accepted as an educational norm; as the studies by Zembal-Saul and by Schwartz demonstrate. Changes can be made that coherently align science courses with methods courses.

SENCER courses can serve as a bridge to connect real-world issues and scientific knowledge with the positive impact of raising motivation and engagement among non-majors’ and preservice elementary teaches’ to learn science (SENCER, 2009). Evidence shows that learning science within the context of a current social problem helps to motivate preservice teachers and enables them to form goals that include learning scientific concepts and practices (Watters and Ginns, 2000; Sadler, 2009). Preservice elementary teachers who experience scientific practices and do investigations that build and refine scientific evidence and explanations can more informed decision makers about science and the teaching of science.

Evidence-Explanation Continuum Framework

While it is important that SENCER courses successfully motivate preservice elementary teachers to learn about science content, it is also essential that science courses provide opportunities to use scientific knowledge and practices. The targeted science practices for this review of SENCER courses are from the Evidence-Explanation (E-E) continuum (Duschl, 2003, 2008). The E-E continuum represents a step-wise framework of data gathering and analyzing practices. The appeal to adopting the E-E continuum as a framework for designing science education curriculum, instruction and assessment models is that it helps work out the details of the critiquing and communicating discourse processes inherent in TSTS Strand 4 — Participate productively in scientific practices and discourse. The E-E continuum recognizes how cognitive structures and social practices guide judgments about scientific data texts. It does so by formatting into the instructional sequence select junctures of reasoning, e.g., data texts transformations. At each of these junctures or transformations, instruction pauses to allow students to make and report judgments. Then students are encouraged to engage in rhetoric/argument, representation/communication and modeling/theorizing practices. The critical transformations or judgments in the E-E continuum include:

  1. Selecting or generating data to become evidence,
  2. Using evidence to ascertain patterns of evidence and models.
  3. Employing the models and patterns to propose explanations.

Another important judgment is, of course, deciding what data to obtain and what observations or measurements are needed (Lehrer & Schauble, 2006; Petrosino, Lehrer & Schauble, 2003). The development of measurement to launch the E-E continuum is critically important. Such decisions and judgments are critical entities for explicitly teaching students about the nature of science (Duschl, 2000; Kuhn & Reiser, 2004; Kenyon and Reiser, 2004). How raw data are selected and analyzed to be evidence, how evidence is selected and analyzed to generate patterns and models, and how the patterns and models are used for scientific explanations are important ‘transitional’ practices in doing science. Each transition involves data texts and making epistemic judgments about ‘what counts.’

In a full-inquiry or a guided-inquiry, students formulate scientific questions, plan methods, collect data, decide which data to use as evidence, and create patterns and explanations from the selected evidence (Duschl, 2003). Science engagement becomes more of a cognitive and social dialectical process as groups and group members discuss why they differed in data selected to be evidence and varied in the evidence used for explanations (Olson & Loucks-Horsley, 2000). Students’ participating in these interactions tend to build new knowledge and/or to correct previous misconceptions about a scientific concept (Olson & Loucks-Horsley, 2000).

Research Context and Methods

The research question asks to what extent do SENCER courses model and use scientific practices that are linked to obtaining and using evidence to develop explanations? SENCER courses were selected from the SENCER website and examined to determine the opportunities provided to engage in scientific practices. Only SENCER courses designed around environmental topics (e.g., water, earth, soil, rocks) were selected because these courses offer up integrated science opportunities. Next, course syllabi, projects and activities were reviewed to ascertain students use, or the potential for use, of data-driven E-E scientific practices.

SENCER courses were considered to emphasize planning and asking questions if students asked their own research question, designed their own experiment, or designed an engineering project. A course that stressed data collection showed that students went into the field and collected soil, water, or air, or they took measurements of samples. A SENCER course provided students practice in evidence if they decided which data to keep as inferred by students representing data or creating graphs. Practice in evidence was also inferred if students analyzed data later. Students could not complete this activity without deciding which evidence to use. A course gave students experience in patterns if students determined how the evidence was modeled as seen by analysis of evidence or running statistics on evidence. Lastly, a course allowed students to practice using explanation if students connected their project to previous research or theories as seen in library searches, if they made predictions for another phenomenon based off of their results, or if they discussed recommendations. Courses that included scientific content but focused on practices used in the humanities such as research and communication with another culture and were left out of this study. A summary of the criteria for evaluating the courses appears in Table 1,below.

Criteria for Evaluating SENCER Courses
Table 1. Criteria for Evaluating SENCER Courses

The names of the courses located on the SENCER website appear in Tables 2 and 3. Scientific practices identified were recorded as an X in Table 3 with further details on how the course fulfilled the criteria. Courses that did not meet the criteria received an N/R (no result). Each X was worth one point on the scale. Each scientific practice identified was worth one point on the scale. A scale from 1–5 was created to effectively compare scientific practices identified in each of the course modules. A score of 1 indicated that the course module only incorporated one portion of scientific practice, and a score of 5 indicated that the course emphasized all five portions of scientific practice within the E-E continuum. Therefore, a course with a score of 1 did not emphasize scientific practice whereas a course receiving a score of 5 heavily emphasizes scientific practice.

Selected SENCER Courses
Table 2. Selected SENCER Courses

Course demographics were also investigated from the SENCER website. Information researched included type of institution, class size, student year, major and class time (Table 2). Demographic information was then used to interpret any differences seen in level of scientific practice among SENCER course modules.

Results and Findings

The results and findings are reported in 3 sections: Differences in Courses, Common Themes Among Courses, and Demographic Patterns.

Differences in Courses

Differences in courses are presented from the highest emphasis on scientific practices (5) to lowest emphasis of scientific practices (1). Two courses, “The Power of Water” and “Chemistry and the Environment,” received a 5 because they provided students with practice in each aspect of scientific inquiry (Table 3). However, they approached various aspects of inquiry differently due to the nature of the problem being solved. “The Power of Water” took an engineering method in which students designed the most efficient micro-hydro-power turbine for a hypothetical small rural village whereas “Chemistry and the Environment” students formulated their own question to research about some environmental chemistry issue on their campus.

Most of the courses scored a 4 (Table 3), these included “Introduction to Statistics with Community-based Project,” “Chemistry and Policy”, “Renewable Environment: Transforming Urban Neighborhoods,” “Riverscape,” “Environment and Disease,” “Energy and the Environment,” and “Geology and the Development of Modern Africa.” These six courses differed from “The Power of Water” and “Chemistry and the Environment” because they did not allow students to explain their patterns or models. Two courses that received a 4 did expose students to explanation, but left out some other aspect of scientific practices in inquiry. Students in “Chemistry and Policy” did not create their own scientific question to study, and “Riverscape” did not provide students with practice in creating create patterns. The “Riverscape” course is a major source of interest because it was designed specifically for preservice elementary school teachers in the attempt to gain appeal in science and learn scientific practices.

Two courses provided students with the opportunity to use 3 out of 5 practices within scientific inquiry, giving them a score of 3. “Renewable Environment: Transforming Urban Neighborhoods” and “Science in the Connecticut Coast,” allowed students to collect data, provide evidence, and create patterns or models. However, students did not practice the planning and explanation stages of scientific inquiry.

Two courses that gave students experience in the fewest scientific practices scored a 2. There were no courses that scored a 1. “Science, Society, and Global Catastrophe” and “Math Modeling” differed in the inclusion of scientific practices. “Science, Society, Global Catastrophe” gave students training in finding evidence and creating patterns and models but not in the remainder of scientific practices. “Math Modeling” enabled students to practice finding evidence and creating explanations, but the course provided students with the remaining portions of scientific inquiry.

Common Themes Among Courses

SENCER courses with differing levels of scientific practices tended to have common themes for practicing scientific inquiry. One major theme was the use of collaboration as seen through group work on a scientific project. Most course modules shown on the SENCER website specifically state that students work in groups for their projects. Others such as “Riverscape” and “Chemistry and Policy” do not directly state that students do group work, although collaboration is emphasized within the course. The only course that did not emphasize collaboration was “Renewable Environment: Transforming Urban Neighborhoods,” although this information may have been left off of the SENCER website. While not specifically stated within the E-E continuum, collaboration plays an important role within inquiry. Students who are able to discuss scientific concepts with one another can articulate ideas and argue enabling them to reconstruct their own ideas of scientific meaning (Olson & Loucks-Horsley, 2000).

Another common theme among high practice SENCER courses was that students communicated their results with one another in various formats. Most courses incorporated formal presentations at the end of the project for the rest of the class. Others used formal presentations, although they were created for different audiences such as the general public or for a buyer of potential land for diamond extraction. Other course modules such as “Science in the Connecticut Coast” and “Environment and Disease” based communication more on discussion of scientific concepts. Despite differences in the means of presenting ideas in class, communication of results is an important skill essential to inquiry-based learning.

Scored Courses
Table 3. Scored Courses

Demographic Patterns

The SENCER courses differed in demographic information. The total number of students participating in class was widespread between 5 and 130 students (Table 2). Laboratories decreased class size to roughly 20 students. However, more information is needed for “The Power of Water” laboratory class size. Student year ranged from freshmen to graduate students within the course. Student type varied greatly from non-majors and preservice elementary school teachers to math or chemistry majors. Total class time differed among the courses in addition to the way the time spent was scheduled (Table 2).

None of the demographic information influenced the degree to which students gained practice in using science. Although class size is variable among courses, it had no impact on amount of scientific practices emphasized. Courses with large class sizes such as “The Power of Water” and “Energy and the Environment” provided students with similar practice in using science to smaller classes such as “Riverscape.”

Additionally, student major had little impact on scientific practices emphasized within SENCER courses. Majors used a varying number of scientific practices among the courses studied. Math students in “Introduction to Statistics with Community-Based Project” used more areas of scientific practice than math majors in “Math Modeling” as seen in Table 3. Majors also did not use any more scientific practices than non-majors in these courses. “The Power of Water” allowed students to use all 5 elements of scientific practice in inquiry whereas majors in “Math Modeling” were only given the opportunity to practice 2 aspects.

Class year also did not affect the ability to expose students to use scientific practices. As expected, SENCER courses enabled upperclassmen and graduate students to gain practice in conducting science as seen in “Riverscape.” However, many SENCER classes also provided underclassmen with a rich experience in practicing science. For example, “The Power of Water,” consisting of sophomores, provided students with practice in every area of scientific inquiry.

Lastly, class time did not affect student exposure to using scientific practices. Courses that received the same scores consisted of a wide variety of time scheduled. “Chemistry and Policy” devoted much more time toward class time than “Environment and Disease,” but students experienced the same number of scientific practices.

Conclusions

Distinctions in SENCER course characteristics have led to varying opportunities for students to gain experience in doing scientific practice as seen in this study’s scores. Those with the highest scores allow students to have the greatest amount of ownership over their own work. Courses with a score of 5 provide students with the ultimate source of ownership in allowing them to choose their own question to study. Modules with scores of 3 and 4 may not allow students to ask their own questions to study, but they do provide students with responsibility over the remainder of scientific practices in the E-E continuum. Courses with the lowest scores provide students with the least amount of ownership over their own work. Students are given a piece of someone else’s project and continue a small portion of that project. For example, students are given another project’s data set that they are expected to analyze. Future SENCER courses should consider giving students as much ownership over their work as possible to encourage student experience in using scientific practices.

The nature of data collection also had an impact on the level of scientific practices used within course modules. Courses in which there was easy access to collect soil or water samples of interest along with equipment to measure samples showed a higher level of scientific practices within the E-E continuum. Courses such as “Math Modeling” and “Science, Society, and Global Catastrophe” may not have allowed for easy access to gather water or soil samples. Therefore, the course was unable to provide students with the opportunity to gain practice in data collection. “Geology and the Development of Africa” found a loophole that enabled students to gather their own data by using a computer simulation. Students did not actually collect rock samples in this class, but were able to collect data from their computer simulation. Perhaps computer simulations could be used in other courses that do not have easy access to take samples from the environment.

While these characteristics provide critical information to increase a SENCER course’s use of scientific practices, traits that have no effect on level of scientific practices also offer great insight to increase student experience in performing science.

It is reassuring that SENCER courses can be flexible enough in incorporating inquiry for small as well as large class sizes. Future courses using the SENCER approach may be designed knowing that students can successfully learn scientific practices within a large classroom size. SENCER courses may cater to majors and especially to non-majors who have little experience in scientific practices. It is appropriate to use SENCER not only for upper level courses, but it is also critical to apply these modules to lower level classes.

SENCER courses provide a way to incorporate scientific practices within student learning. The integration of social issues with science builds preservice teacher interest in scientific practices. As these students gain experience in using scientific tools, they become more confident in incorporating science into their future elementary classroom. Perhaps our future teachers’ greater enthusiasm for science will spark student interest in the sciences.
