The project was developed in the fall of 1969 to field test and evaluate prototype social studies units for kindergarten, and grades one, two, and three. The units focused on major concepts drawn from the social sciences, expanding horizontal organization of content, shifting from a basal textbook to a series of supplementary materials, and using an inquiry-oriented approach to knowledge. It was assumed that teacher-developed materials would prove more meaningful for pupils than commercial materials. The major purpose of the project was to see if these units could be effectively used by a sample of North Carolina teachers. They hoped to use the systematic feedback from forty teachers in ten schools and three kindergartens to increase the effectiveness of the units, and to assess the support the teachers might expect to find in most schools with regard to supplementary materials. Two-day conferences served the teacher orientation information gathering functions; three questionnaires were administered on teacher attitudes, current school status, and the effectiveness of conference-type inservice training. After the conference series, the sample units were taught for seven weeks. Next, a final questionnaire was administered to measure school personnel attitudes and teacher assessment of the units, and a summative conference was called. The success of the units, the training, and the project as a whole was borne out. (Author/SBE)
