The International Environmental Education Programme (IEEP) of UNESCO has developed a series of teacher training modules in environmental education. This experimental module focuses on the pre-service training of secondary school science teachers and supervisors. The six chapters of the document address: (1) the environmental problem and education's response; (2) the connections between science education and environmental education (including basic skills in science and environmental education and the relationship of science, society and technology); (3) curriculum tasks in environmental education for science teachers (particularly those relating to environmental problem solving and action strategies); (4) teaching strategies and activities; (5) evaluation of environmental education programs (with regard to societal aspects of science learning and instructional materials); and (6) the implementation of environmental education at both the school building and school district levels. The appendices contain a listing of science concepts of particular importance in environmental education, definitions and aims of environmental education, the declaration of the Tbilisi Intergovernmental Conference on Environmental Education, a description of IEEP, and a bibliography.
