This student textbook and accompanying teacher supplement strive to provide objective instruction in global environmental issues. Twenty-six study units present facts, opinions, and consequences of environmental issues, as well as responses which have been, and could be, made to the environmental issues. Each unit is introduced by a newspaper headline and contains: (1) discussion and background information on a specific environmental issue: (2) open-ended questions intended to encourage further study and understanding; (3) activities that can be done in the classroom or home environment; and (4) references to related careers, organizations, source citations, suggested readings, and viewings. Appendices provide a listing of Canadian, U.S. federal, U.S. state, and private sector environmental organizations; an historical listing of environmental laws; a glossary, and an index. A teacher supplement provides: (1) teaching frameworks; (2) answers to open-ended questions; (3) listings of both printed and audio-visual supplementary materials; (4) background on performance-based learning, portfolios, and cooperative project assessment; (5) procedural recommendations for 11 project assessments; (6) a two-stage approach to research report evaluation; (7) 12 projects and assessments; and (8) reproducible student assessment masters that detail task, procedure, and evaluation rubric.
