Twenty-nine case studies presented in this document, all drawn from the ERIC data base and thus accessible through ERIC microfiche collections, have as their common denominator the efforts of individuals, organizations, and agencies to affect and/or accommodate change through environmental education. Their targets, representing all age levels, range from single classrooms and small communities to national and international audiences. Papers are intended (in the context of this volume) to represent the spectrum of "environmental education change agent" activity of the present and recent past. An attempt was made to exclude reports of "environmental activist change agent" activities, as distinguished from "environmental education change agent," for reasons discussed in the foreword. However, several papers dealing with environmental activism were selected because of their implications for education. Titles and authors of papers are included in the table of contents. A short abstract and original source (together with ERIC ED number) are provided on the first page of each paper. (Author/JN)
