This report summarizes the planning and implementation of an Educational System for the Seventies (ES-70), a research and demonstration program for developing a relevant, individualized, and economically feasible secondary school curriculum and organization. Research efforts are patterned to establish performance objectives for selected activities, design courses of studies, select media and materials, and develop teaching strategies. Project participants include 19 local school districts, their respective State education departments, the U.S. Office of Education, and other interested organizations. Five appendixes include statements on the project scope; correspondence; a list of related reports, brochures, newsletters, and other papers; inventories of project-related materials, and samples of the ES-70 NEWS. Related documents are ED 032 630 and ED 032 631. (Appendix B. Copies of Correspondence ppB1-13, may be of poor quality when reproduced because of marginal legibility.) (Author/LLR)
