Furnished in this comprehensive report is a resume of a five-year experimental program in environmental education conducted by the Eastern Montana College Laboratory School in conjunction with Eastern Montana College and the Billings School District #2. The basic purpose of the program is to make teachers, and in turn students, aware of the possibilities of studying the outdoors right outside their classrooms. This learning can then enhance the culminating activity of field instruction at a resident school camp. The resume gives a brief history, definition and statement of the need for environmental education, together with a summary of the objectives, content, curriculum, financing, management, and growth of the environmental education program from 1966 to 1971. Guidelines for establishing an interdisciplinary environmental education program are outlined, based on an evaluation instruemtn prepared by Dr. Helen Grilley, Eastern Montana College. This cites principles, objectives, methods used including pre-planning, follow-up, and evaluation, and curriculum experiences in seven subject areas. Numerous appendices present administrative details, camp program schedules, and teacher workship information. (BL)
