This source book describes 107 projects administered by the U.S. Department of Education under the Pre-College Teacher Development in Science (PTDS) Program from 1980-82. Under the program, grants of up to $50,000 were made to colleges, universities, and museums to assist them in providing opportunities to elementary teachers for continuing education in mathematics, science, and social sciences. Projects were primarily academic year seminars of summer workshops and seminars. Although projects were subject matter oriented, the emphasis varied from those designed for teachers in need of subject-matter training in the traditional disciplines to those designed to present science subject matter in an interdisciplinary/multidisciplinary mode. Title, name and address of project director, project summary (including goals and objectives), funding year, amount of funding, and discipline(s) are provided for each project. The major intent of this document is to serve as a resource for the planning of future projects based on the federally funded models described. Since elementary teachers have been extremely responsive to these projects, it is hoped that the states will consider providing similar opportunities for the improved teaching of science and mathematics in the elementary school in their jurisdiction.
