During the first two years of operation the Marin Social Studies Project field tested a variety of newly developed social studies curriculum materials throughout Marin County. This document is a compilation of the data which was collected from teachers and students regarding these materials. The results are reported in three sections: primary (K-3), elementary (4-6), and secondary (7-12). The first part of each section contains student responses to questions given in percentages. Unedited responses of the teachers who used the experimental materials in their classrooms are included. Related documents are SO 006 450-454. (Author/SHM)
