This document summarizes, analyzes, and reflects upon the activities of the Southeastern Regional Center for the Improvement of Elementary School Social Studies established at Florida State University in Tallahassee, Florida. There are five major parts to the report. Part I contains a narrative summary of regional center activity from 1969 to 1971. Serving the states of Florida, Alabama, Georgia, and the Carolinas, the Center had three general objectives: (1) to strengthen the professional education of teachers; (2) to provide a means for successful implementation of new social studies curricula; and (3) to create a setting for research on problems of teacher training and curriculum innovation. "Man: A Course of Study" (MACOS), a conceptually designed, inquiry oriented, multimedia social science curriculum designed by the Educational Development Center, was selected as the most viable vehicle through which to implement the Center's stated objectives. The second part of the report discusses a community controversy which arose when a group known as Citizens for Moral Education sought to remove MACOS from the Columbia County public schools in Florida in November 1970. This case has particular merit for those who are interested in the support systems necessary for curriculum innovation. Part III evaluates the two week summer institute conducted for teachers by the Center in 1971. Teachers evaluated the institute, their MACOS training, and MACOS as a curriculum. Part IV contains reflections and generalizations of the directors regarding the entire project. Numerous appendices containing such items as brochures, participant lists, and survey instruments are included in Part V. (RM)
