A revision of the 1979 publication, this document presents the educational objectives and course descriptions of the social studies program for grades K-8 of the Montgomery County Public Schools, Rockville, Maryland. The document begins by outlining the social studies themes and units for each grade level, by describing the program and its relationship to other curriculum areas, and by listing career education instructional objectives in social studies. For each grade level, an overview is presented of the social studies program and a listing of educational objectives for unit themes. The program is designed around a sequence on "expanding horizons." This design begins with the student's immediate environment and expands into the community, state, nation, and world, developing a global perspective. The program provides activities which help learners to develop the knowledge, attitudes, and skills necessary for effective citizenship in a democratic society. Through the integration of content and attitudinal and skill objectives, the program shows the interrelationships among the physical, cultural, and global environments in which people live. (RM)
