This paper incorporates the work of several authors and presents a project focused on the competency training of teachers in environmental education. Draft competency lists included: (1) scientific knowledge for elementary school teachers; (2) processes in science for the elementary school teacher; and (3) teaching science to elementary school age children. The Florida and AAAS guidelines and other Competency-Based Teacher Education Program (CBTEP) materials were major input sources. After selection of the teachers for the CBTEP training in environmental education competencies, a series of informal training sessions were conducted. Materials related to the SCIS Life Science Units were utilized. Questionnaires, classroom visits, anecdotal records of classroom activity written by the teacher and samples of children's work provided data for the project. A modification of the Richmond Evaluation of Teacher Objectives for Environmental Unit instrument was administered to the teacher at the conclusion of the unit. Conclusions and recommendations were made concerning the effectiveness of the program. These are listed in the final report. (Author/EB)
