Contained are 25 descriptions of teacher education programs for environmental education offered by colleges and universities in the United States. These programs were identified on the basis of recommendations from specialists in the state education agencies and reflect a broad spectrum of approaches and emphases. The case studies include: (1) teacher certification programs; (2) bachelor's and master's degree programs; (3) inservice workshops; and (4) courses in environmental studies, conservation, natural history, and marine science. Several of the efforts discussed involve personnel from and student experience with public and private agencies with environment-related concerns. (Author/WB)
