Teaching Environmental Issues and the Affective Domain
What are some strategies to teach environmental topics, particularly controversial ones, without coming up against affective barriers to learning? How can you help students learn the science and the policy without getting weighed down by feeling guilty or defiant?
- Teach the science first
Even though most environmental topics are a blend of science, policy, economics and human impacts, it may be helpful to separate these into three distinct sub-topics. First, present the science objectively, using data and relevant examples. Next, discuss the policy and economic issues related to this topic. Once those subjects are covered thoroughly, students will often be interested to learn what their own personal stake may be. By setting the stage deliberately, students are more likely to be receptive to the information and are less likely to get turned off.
- Teach with data
Statements like "species are going extinct at an alarming rate," "wetlands are being turned into strip malls," and "the climate is getting hotter"are emotional statements (even if true) and will elicit emotional responses in your students. Rather than risk sounding like an alarmist, let the data speak for itself. Have students work through data sets, and they can discover for themselves the rate and extent of environmental change. In some cases, they still may end up being surprised or emotional, but it's because they reached their own conclusion, not because you told them to be alarmed. [Schweizer and Kelly, 2005]
- Use active learning techniques
Students learn better when the can learn it for themselves, and this is especially true for topics that are potential turn-offs for students. Environmental issues lend themselves to teaching techniques like using local examples, gathering data from the field, using role-playing or debates, or participating in environmental projects.

- Controversy, ambiguity, and topics with incomplete or missing evidence can be used constructively (but need to be introduced judiciously)
Engaging controversial topics, or topics that have no clear-cut answers, can create an environment where students are motivated to learn more out of curiosity or imminent need [e.g. Edelson, 2001 ]. Students can be encouraged to review what is known, to identify what additional information is needed to solve the problem, and to continue the search to find and critically examine new information. Learning goals for students can include development of "scientific habits of the mind" [AAAS, 1989 (more info) ], to be critical consumers of information, and to be able to create, present and rebut arguments based on evidence. A supportive environment needs to be created to encourage scholarly and open review of the arguments and ideas, and provisions need to be put in place to prevent interpersonal (ad hominem) attacks in reporting results in class activities.
- It's not all doom and gloom
Certain environmental topics can be downright depressing. However, there are also many environmental success stories. Strive for a balance in which students do not feel overwhelmed by a preponderance of "bad news." After all, environmental successes provide relevant examples of how problems can be overcome.
- Clearly define your role and your teaching approach
There are many ways to teach environmental issues. Before jumping into your curriculum, consider what your desired outcomes are and what approach you will take. Is your intent to teach just the relevant scientific processes, to promote an awareness of environmental issues, or to lead students toward a shift in their own environmental behavior? In the classroom, do you assume the role of environmental guardian, a free-marketeer, or a devil's advocate? There are advantages to various approaches, but it's important to consciously consider what your goals are and how you can best achieve them. [Corney, 1998]
- Lead by example, but don't preach
We all know the stereotype that college professors drive tiny, efficient cars and live an eco-minded lifestyle. Regardless of whether or not this describes you, it's best to avoid talking down to your students for their own personal choices. Preaching to the class about what's "good" and what's "bad" will likely have the opposite effect than you intended; it can be a major turn-off for students. If your goal is to promote environmentally-favorable behavior in your students, consider a hands-on project that will challenge students to consider the environmental impacts of their own actions.

Resources and Examples
Teaching and learning in environmental education: Developing environmental conceptions (Ballantyne and Packer, 1996)
citation and bibliographic information This paper discusses how environmental education is closely connected with the affective domain in that it involves attitudes, values and behaviors, in addition to cognitive knowledge. The authors recommend that teachers develop conceptions in environmental education by using a range of strategies designed to integrate an individual's environmental knowledge, attitudes/values, and behavior. The application of constructivist learning provides a basis for encouraging students to become aware of their environmental conceptions, challenge inconsistencies in those conceptions, and make informed decisions regarding their environmental conceptions.
Enhancing environmental conceptions: An evaluation of cognitive conflict and structured controversy learning units (Ballantyne and Bain, 1995)
citation and bibliographic information Learning experiences which challenge and enhance students' conceptions of environmental issues and environmental education by confronting them with alternative viewpoints and evidence were trialed in two postgraduate environmental teacher education courses. Findings indicate that as a result of participating in the learning experiences, students formulated their own position more clearly, better understood the viewpoints of others, became aware of inadequacies and inconsistencies in their conceptions and were challenged to increase their environmental commitment.
Learning to Teach Environmental Issues (Corney, 1998)
citation and bibliographic information This paper describes preliminary results from a qualitative research study into the thinking and practice of student geography teachers in the teaching of environmental issues. The study investigates ways that teachers think about environmental issues and the corresponding ways that teachers teach these topics. The author points out that teachers must make various value judgments in teaching environmental issues.
A Multivariate Analysis of the Relationship Between Attitude Toward Science and Attitude Toward the Environment (Ma and Bateson, 1999)
citation and bibliographic information This statistical study identified the relationship between students' attitude toward science and attitude toward the environment. Canadian 9th grade students answered sets of attitude questions about the environment and about science in general. The strongest correlation was that students who had a positive attitude toward science also had a positive attitude toward science. Another correlation indicated that students favored preservation of natural resources but also did not favor a reduction in freedom for logging companies, farmers, automobile drivers, and so on.
Developing Analytical and Communication Skills in a Mock-Trial Course Based on the Famous Woburn, Massachusetts Case (Bair, 2000)
This paper describes an interdisciplinary course based on the book A Civil Action. Students analyze aerial photographs, well logs, streamflow records, permeability tests, and water-level and water-quality data from the trial to complete assignments that become exhibits in the mock trial. Assignments include construction of geologic cross sections, potentiometric maps, hydrographs, flood recurrence graphs, and calculation of hydraulic gradients, groundwater velocities, and contaminant travel times. The course teaches students how to develop and defend their opinions, how to question the opinions of others, the limitations of data collection and analysis, and the importance of integrating computational and communication skills.
The Use of a Mock Environment Summit to Support Learning about Global Climate Change (Gautier and Rebich, 2005)
citation and bibliographic information This paper describes a course that addresses the human aspects of global change through the development and negotiation of an international environmental agreement. Students play the roles of country representatives and participate in activities such as writings, class discussions, presentations and negotiations.
An Investigation of Student Engagement in a Global Warming Debate (Schweizer and Kelly, 2005)
citation and bibliographic information This study investigates how using debate as a pedagogical tool for addressing earth system science concepts can promote active student learning, present a realistic and dynamic view of science, and provide a mechanism for integrating the scientific, political and social dimensions of global environmental change. The investigation examines how students make use of observationally-based climatic data sets when debating the cause of global warming.

In the Trenches - July 2015 Special Issue: Teaching about Fracking
This special issue of In the Trenches focuses on the complex set of processes for extracting oil and natural gas known as slickwater horizontal high volume hydraulic fracturing, more commonly known as "fracking." It also includes links to example activities.
This case recognizes the teachable moment provided by the heightened interest in where our energy comes from. It offers an eight hour program (designed as a teacher professional development workshop, but adaptable to undergraduate or high school courses) that complexifies what seems like a simple issue to many. It also includes links to an array of resources that provide instructional materials for teaching activities for as short as a single class or provide the foundation to a course. Investigating the environmental, cultural, and economic impacts of hydrofracking and contextualizing it in the broader energy system highlights a wide range of ethical questions and draws attention to a simple (sort of) bottom line: We need to use a lot less energy. (Also see the Activity sheet describing this resource.)

This activity is designed to engage students in a practical exercise in land use planning, to make the students aware of the positive and negative aspects of land use laws and local zoning ordinances through role-playing. The students represent groups interested in purchasing the same piece of land. Each group must research to devise a plan that is legal and attractive and present proposals to convince the current owners to sell the land to their group. The instructor is advised to use a real plot of land so that real land use laws can be researched.
