From the initial invitation for proposals from the U.S. Department of Health, Education, and Welfare in 1962 until their end the reorganization of 1971, 16 "Project Social Studies Curriculum Centers" (PSSCC) existed at universities throughout the country. Social Studies programs came under fire from the educational reformers of the early 1960's. The activity-type social studies curriculum was viewed by some as too much play and not enough work. The PSSCC objectives were ambitious, reflecting both reforming zeal and naivete. Little is known about the administrative and organizational process the U.S. Office of Education used with the PSSCC. The result was a considerable degree of bureaucratic disorganization. The staffs of the centers in some ways determined the nature of the centers. The previous social studies curriculum development activities had not made such a conscious effort to combine the knowledge, skills, and experience of classroom teachers and university faculty. The materials and strategies produced represented the view points of a wider variety of scholars that had been true in previous attempts to write curriculum materials. The designs of the individual PSSCC organizational schema were practical and experimental, as were most of the developmental processes. Instructional strategies gave greater emphasis to decision-making and inquiry skills. While content objectives did not decrease in importance, the objectives of methods and strategies of the PSSCC were more process oriented. (PPB)
