Cooperating with the Canadian Commission for UNESCO, the Ontario Institute for Studies in Education has prepared boxes of experimental curriculum materials on the subject of ecology. This guide summarizes the design and contents of the boxes and provides instructions for those using the boxes--principals, teachers, parents, librarians, and students. A complete box may be considered an in-depth course of study, and the instructions for users are based on this approach. The three-week experimental course is designed for students in grades 7 to 13 and requires devoting their entire time to the course for this period. Students are expected to master the general principles of ecology and study one ecology idea in depth. Suggestions for the ecology course include: step-by-step instructions for building the ecology continuum for Week 1; ten ecology ideas (entropy, ocean, growth, energy, dirt, rock, forest, diversity, environment, cycles) for Week 2; and an ecology exhibition for Week 3 based on the individual student study of ecology ideas. Materials contained in the EcoBoxes are noted in the final section. These include books, magazines, records, films, posters, prints, charts, maps, tapes, games, and multi-media kits. Resources for additional information are also listed. (BL)
