The Data Book contains descriptive analyses of new social studies materials for kindergarten through Grade 12, teacher resource materials, ERIC abstracts of curriculum guides, and a listing of all social studies materials published in 1979. It is intended to help teachers, administrators, curriculum coordinators, and college methods professors in selecting appropriate materials on the basis of grade level, discipline, underlying philosophy, goals, strategy, structure, content, innovativeness, and merit. Four major sections comprise the book. Section One includes 63 two-page analyses of social studies textbooks and supplementary and nonprint materials. Section Two contains 20 short analyses of teacher resource materials. Each analysis summarizes the purpose, intended uses and users, and contents of each resource book. Section Three provides abstracts of 20 social studies curriculum guides identified through the ERIC system. Section Four contains a listing of 644 social studies materials published in 1979 and is organized by subject area. Each section is indexed according to author/editor, developer, grade level, publisher/institution, and subject area. (Author/KC)
