PLAN Social studies curriculum attempts to assure that each student achieves educational objectives appropriate to his individual needs and interests. The guiding framework is presented in the form of a list of over one hundred long-range objectives (LRO's). The major objective areas are: inquiry, problem-solving and planning, affective objectives, social skills, quantitative skills, and knowledge objectives. Chapter 3 describes the curriculum for each level roughly corresponding to grades one through twelve, emphasizing the content and settings to which major objectives are applied. Chapter 4 presents a series of charts in which the explicit instructional objectives of the existing curriculum are identified both by level and by the (LRO) they serve. The order in which the content areas are presented is not dictated by the structure of the objectives; the instructional sequence can be shaped largely by the personal interests of the students and the availability of instructional materials. The key concepts, principles and facts of each knowledge objective are appended: social problems, history, cultures, sociology, anthropology, religions, American ethnic groups, American institutions, sociology, anthropology, religions, American ethnic groups, American institutions, social psychology, individual behavior, political science, American civics, basic economics, personal economics, geography and ecology.
