Some directions and avenues of thought are suggested to help school personnel develop sites for environmental education. In approaching the use or development of a site, important steps are (1) involving students, teachers, administrators, parents, and community representatives; (2) determining educational goals on the basis of students' needs; and (3) developing a resource list. Suggestions are made of ways different disciplines can be involved with the site, emphasizing that action-oriented activities are the ones most successful with students. Three site analyses prepared for schools considering development of their properties are included to provide more detailed use and development instructions, to give an idea of the variety of usable natural sites, to suggest possible planning formats, and to illustrate what a completed inventory and plan might look like. A bibliography, a list of relevant organizations, and a site analysis inventory checklist conclude the report. (Author/MLF)
