Middle school and high school students need to develop many skills in order to investigate environmental issues and know the basics of citizenship action strategies. This student guide is designed to teach students how to investigate and evaluate environmental issues and actions. The guide is presented in six modules. Module 1 introduces the concept of environmental problem solving through activities in which the students examine the definition of the term environment, the effects of environmental interactions, pictorial illustrations of environmental issues, environmental beliefs and values, and the basics of issue analysis. Module 2 gives students the skills to collect information needed to investigate an environmental issue. Students learn to identify an issue, formulate research questions, compare information resources, identify resource people, summarize information, and search for references. Module 3 introduces students to the use of surveys, questionnaires, and opinionnaires. Students study the rules governing the use of surveys and questionnaires, learn to distinguish between the three research methods, learn the rules of sampling populations, and summarize data collection techniques. Module 4 helps students understand basic types of data interpretation. Module 5 provides students with activities that lead the students through the investigation of an environmental issue of their choice. Module 6 provides students with the skills to become active participants in solving environmental issues. A teacher's edition is appended to the book. It provides suggestions for teaching the exercises associated with each module. (MDH)
