An overview of current developments in outdoor education and environmental studies in Canada is presented in this booklet. Compiled for the Canadian Education Association, the study reviews trends and developments since a similar survey was undertaken in 1969. The first half of the report traces the beginnings of outdoor education programs in Canada; defines outdoor education together with its objectives and values; evaluates use of the mobile classroom, primarily the school bus; suggests opportunities for creativity in all grade levels and subject areas; lists examples of what teachers are doing to enrich their programs in numerous disciplines; advises where to start a program and whom to contact for voluntary assistance; enumerates special problems encountered in teaching in the out-of-doors; and presents reactions from involved individuals--pupils, teachers, parents, and administrators. The second half is a resume of programs, plans, and problems in each of the provinces, followed by a sampling of special or unusual activities. Recommendations and final comments conclude the work accompanied by selected reference materials written by Canadian authors. (BL)
