To improve social studies instruction and curriculum content in the United States, Northwestern University and the North Central Association Foreign Relations Project conducted 14 experimental seminars (1964-69) in which 894 teachers and administrators from 25 states took part. To determine the effectiveness of the seminars, two surveys were taken, one after the fourth seminar and one after the last. In the first survey, 30 educators agreed that the seminars had been effective in producing curriculum revisions and that they had changed teacher attitudes. In the other, 96 participants representing all seminars indicated that they (1) responded favorably to the "status and involvement roles" afforded by the seminars, (2) took part, in their own schools, in the preparation of social studies curriculums and of units on democracy and totalitarianism, (3) brought fresh ideas into the curriculums from the seminar, (4) applied the informed opinions of university specialists and scholars to their educational situations, and (5) incorporated new materials and approaches directly into the social studies curriculum.
