    Description: How to teach Environmental Education.


    Classroom Component: I. What is Environmental Education?

      Environmental Education (hence forth referred to as EE) has quite a long history (some sources even point as far back as Aristotle!). However, before the late 1960s the term only focused on the idea of nature studies. As far back as the mid-1800s Louis Agassiz stated that students should “study nature, not books." In the 1920s L.B. Sharp, a well-respected philosopher of outdoor education stated, “Teach outdoors what is best taught outdoors and indoors what is most appropriate there." In the 1960’s, the term was defined as education that focuses on the environment (Disinger, quoted in Wilke,1993). The most accepted and frequently quoted definition was provided in 1969 by William Stapp: “Environmental education is aimed at producing a citizenry that is knowledgeable concerning the biophysical environment and its associated problems, aware of how to help solve those problems and motivated to work toward their solution.” Stapp’s definition, when combined with the twelve principles developed at the United Nations Educational, Scientific, and Cultural Organization (UNESCO) conference at Tbilisi, Georgia (in the former USSR), create the guidelines used by environmental educators today. The report (UNESCO, 1978) stated: Environmental education should-
      • Consider the environment in its totality - natural and built, technological and social (economic, political, cultural-historical, moral, aesthetic);
      • Be a continuous lifelong process, beginning at the pre-school level and continuing through all formal and non-formal stages;
      • Be interdisciplinary in its approach, drawing on the specific content of each discipline in making possible a holistic and balance perspective;
      • Examine major environmental issues from local, national, regional and international points of view so that students receive insights into environmental conditions in other geographical areas;
      • Focus on current and potential environmental situations, while taking into account the historical perspective;
      • Promote the value and necessity of local, national and international cooperation in the prevention and solution of environmental problems;
      • Explicitly consider environmental aspects in plans for development and growth;
      • Enable learners to have a role in planning their learning experiences and provide an opportunity for making decisions and accepting their consequences;
      • Relate environmental sensitivity, knowledge, problem-solving skills and values clarification to every age, but with special emphasis on environmental sensitivity to the learner’s own community in early years;
      • Help learners discover the symptoms and real causes of environmental problems;
      • Emphasize the complexity of environmental problems and thus the need to develop critical thinking and problem-solving skills;
      • Utilize diverse learning environments and a broad array of educational approaches to teaching/learning about and from the environment with due stress on practical activities and first-hand experience.
    II. An Environmental Educator vs. An Environmentalist
      Many times EE comes under fire due to a misconception by the general public, they hear the words environmental education but visualize an environmentalist (and even that picture is an incorrect one that views all environmentalists as trouble-making activists). John Hug, Environmental Education supervisor for the Ohio Department of Education offers some explanations in the Project Learning Tree PreK-8 Activity Guide. Hug states, “Any world citizen who advocates with greater or lesser action that the wrongs against our environment must be stopped is an environmentalist.” Hug identifies an environmental educator as one who “is any world citizen who uses information and the educational process to help people analyze the merits of the many and varied points of view usually present on a given environmental issue,” “one who is a developer of skills,” and “an information analyst who prepares the people (from any segment of the population) who will participate in environmental decision making.” You, as an environmental educator, have the right to be an environmentalist but in the classroom you must remain value fair and value free. You must create a climate where students hear and examine all views of an issue before they decide what their belief will be.
    III. How Do You Teach EE??
      One method that works well at the middle school level is to use environmental problem solving. There are certainly enough problems out there, and I try to steer students toward one of local concern. (See Appendix I for more information) There are just three basic steps:
    • Explore and Define the Problem (figure out what is going on)
    • Search for and Identify the Solutions (figure out what to do)
    • Implement and Evaluate Actions. (do something!)
    • If we refer back to Stapp in section I, we find these 3 steps make up his definition of EE.
    IV. Sounds Like A Lot of Work!!!
      Don’t panic, there are several existing models of environmental problem-solving from which to choose. You need to pick the method that best matches your teaching style and classroom situation. The four models featured below are the best known and most accepted. It is easiest to think about them on a continuum beginning with the first as having the least structure to the last one having the greatest structure.
      • Least Structured -- Ian Robottom. In this model both students and teachers explore a local controversial issue. Students research and gather knowledge about the issue and develop strategies to solve the problem. Robottom considers the student’s investigation to be their action. His goal for the student’s end result is a change in the relationship between the community and the environment. Throughout this process the skills that the students need to become problem-solvers will emerge as they evaluate and reflect on their role in the situation. Students learn by experience and the teacher takes on the role of a collaborator. Whole class groups are involved at one time. Evaluation of student’s progress is ongoing through constant reflection. There are no set objectives. There are no pretaught skills.
      • A Bit More Structure -- William Stapp and Arjen Wals. Known as The Action Research Community Problem Solving process, the authors believe students should play a role in planning activities and should have the opportunity to take action. They feel students do not have to fully understand an environmental problem before they take some action to solve it. Students would then assess the outcome of their action and make adjustments. This process may then be repeated as students continue to discover new perspectives on the problem. Here the teacher acts as the facilitator and may be a source of information and coordinator of group activities. The entire class works on the problem with small groups looking at different aspects. Evaluation is in the form of student reflection and self-assessment of growth as seen in the success of the action, journals and logs.
      • Even More Structure -- William Hammond and The Monday Club. This model involves students who only meet once a week. The students are the leaders whose leadership qualities are strengthened by training, support and meeting success. The class selects an issue and designs a plan to resolve the issue. This would involve elected leaders and community action. The use of group problem solving is a key component and is developed through direct instruction and coaching by the teacher. The teacher provides instruction on skills such as interviewing, problem solving, and lobbying and may even choose the issue. Students then brainstorm solutions, actions and expectations. Evaluation involves the use of journals, amount of time invested, and grades given through mutual consensus of the teacher and the student.
      • Greatest Amount of Structure -- Hungerford and Volk --Investigating and Evaluating Environmental Issues and Actions. The students are taught the skills necessary to investigate a local issue of their choosing. There is a published manual to guide the students and teacher through this process. They are assigned activities that provide opportunities to practice these new skills. Students then select a local issue to investigate. This may be done as an individual, a small group, or a total class. After researching all views of the issue students must conduct a survey of a selected population and generate suggested actions that could help correct the issue. They do not have to follow through on their selected action. The teacher begins as an instructor and eventually becomes a facilitator in this model. Evaluation can be in the form of paper and pencil activities, teacher made skills test, and student oral and written reports.
      All four of these model do follow the accepted definition of EE as provided by Stapp (see section I) and do allow for the incorporation of the twelve principles set forth by the 1978 UNESCO conference report from Tbilisi. So, as stated at the beginning of this section, the choice of the model is up to you as determined by your teaching style and situation. We have selected the last method, the Hungerford and Volk model, as the one that fits our needs and that we are most comfortable using. Therefore the rest of this presentation is devoted to further explaining this method and sharing our successes with its use.
    V. Hungerford and Volk : Investigating and Evaluating Environmental Issues and Actions (IEEIA)
      The model begins with the idea that students should progress through four goal levels of issue instruction. These goals are
      • Foundation of Knowledge
      • Issue Awareness
      • Issue Investigation and Evaluation
      • Citizenship Action
      The first level deals with a foundation of knowledge. At this level the student develops sufficient knowledge of ecology “to make sound decisions with respect to both humans and the environment” (Hungerford and Volk, 1996). Concepts included in this goal are
      • population dynamics
      • interactions
      • limiting factors
      • energy transfers
      • ecosystems
      • succession
      • biogeochemical cycling
      • interdependence
      • man as an ecological variable
      Students don’t need to know them by these names. This may sound like a lot to accomplish but you may be surprised to learn that many of your students already have this information. Many educators believe that environmental education means just providing this kind of knowledge. To see how much information your students already possess you could, of course, give a pre test. You can develop one yourself or check in the teacher materials in some old life science test banks. We have discovered the Children’s Environmental Attitudes and Knowledge Scale by John M. Ramsey to be very effective. (see the bibliography for more information). The second goal is issue awareness. This goal, much like the first, attempts to provide students with knowledge. But now the knowledge is about specific environmental issues, preferably of local concern. Concepts that the student must understand from this goal include
      • how human cultural and individual behaviors impact the environment
      • the alternative solutions that might solve or partially solve an issue
      • how values and beliefs play a part in decision-making
      • the need for responsible citizen action in an attempt to solve an issue
      By selecting a topic and following the sequence tree show in Appendix II students may practice this skill. I like to use a film by the Audubon Society on wolves and their reintroduction into Northern United States and Yellowstone National Park. Ray uses articles found in the Missouri Conservationist Magazine (see Appendix III for his format). After students have been introduced to the concepts of events, problems, issues and solutions, they must then identify the players and their positions which are based on the players beliefs and values. Appendix IV provides some definitions and a list of value descriptors to help students with this concept. The third goal is issue investigation and evaluation. This goal attempts to develop the skills necessary for research and investigation techniques. This is the meat of the program. Skills to be developed in this section are
      • identifying an issue
      • collecting and sorting data
      • identifying research questions
      • finding environmental information
      • finding both sides of the issue
      • summarizing information
      • library skills
      • developing surveys, questionnaires and opinionnaires
      • sampling basics
      • collecting data
      • interpreting data, graphing
      • drawing conclusions, making inferences
      • reaching a recommendation
      This section covers many skills that are recommended by the Show Me Standards. The IEEIA book contains many activities as well as resources to accomplish these skills. But this is just the warm up for the big event. After the students practice these skills they then put them to work as they use these tools to investigate their own issue of local concern. They should have been thinking about this all along. Now comes the time to investigate their issue. Goal four is citizenship action If the students have successfully investigated an issue they should now have the desire to take action. However they may not have the ability to do this. Concepts included in this section include
      • identifying an action
      • methods of action
      • guidelines for decision-making
      • action analysis criteria
      • types of actions such as logical and emotional appeals, coercion, persuasion, letters, consumer boycotting and conservation, political action
      • predicting possible consequences of actions
      • deciding on a action
      At this point students may actually be ready to take action but that is not necessary. If you feel secure enough to allow the students to take the action and can help them then now is the time to act.
    APPENDIX I Local Issues and How To Find Them
      As a portion of their grade for this project, I have students gather newspaper and magazine articles about local environmental issues. In the past, I have expanded my definition of local to include issues from our state. Be sure to set a date stipulation for these articles, say within the past 6 months or the past year. Articles and written summaries were due each Friday for seven weeks. Before they turned in the articles they had to share it with at least 3 other students (their lab partners). Each student kept a page in their journals briefly listing the environmental issue that was being shared. If there was time, I would then ask for volunteers to share their articles with the entire class, instructing the other students to add this issue to their list if they didn’t already have it. Articles and written summaries were graded and the summaries returned. The article itself was placed in a class binder for future reference when the issue investigation portion began. I also allowed students to bring in up to five extra articles and summaries for extra credit.
    Some Issues Students Have Investigated in The Past
    • Dioxin Contamination at Times Beach
    • Incineration as a Method of Dioxin Decontamination
    • Reintroduction of Wolves
    • Reintroduction and Trapping of River Otters
    • Recreational Use of Missouri Rivers
    • Air Pollution in St. Louis
    • Recreational Use of Missouri Caves
    • Destruction of Wetlands
    • Recycling of Plastics

    Action Analysis Criteria Hungerford and Volk, 1996 The authors have identified a total of fourteen questions that seem important to ask before proceeding with an environmental action. See if yours agree with those that follow:
  • Is there sufficient evidence to warrant action on this issue?
  • Are there alternative actions available for use? What are they?
  • Is the action chosen the most effective one available?
  • Are there legal consequences of this action? If so, what are they?
  • Will there be social consequences of this action? If so, what are they?
  • Will there be economic consequences of this action? If so, what are they?
  • What are the ecological consequences of this action?
  • Do my personal values support this action?
  • Do I understand the beliefs and values of others involved in this issue?
  • Do I understand the procedures necessary to take this action?
  • Do I have the skills needed to complete this action?
  • Do I have the courage to take this action?
  • Do I have the time needed to complete this action?
  • Do I have all the other resources (other than the above) needed to make this action effective?
  • Have you identified a question that is not on this list that should be asked by someone who intends to take action? It might be an excellent one if you have. Discuss it with your classmates and your instructor. The questions above are useful in testing all the types of environmental action, whether they are political action, ecomanagement, consumer action, or persuasion.
