This junior high teaching unit on careers in public service is one in a series of career guidebooks developed by Project CHOICE (Children Have Options in Career Education) to provide the classroom teacher with a source of career-related activities linking classroom experiences with the world of work. The unit follows a typical format that includes the rationale, goals, performance objectives, instructional strategy, evaluation, and suggested instructional materials (including books, films, and filmstrips). The remainder of the unit is comprised of instructional activities designed to acquaint students with careers in four public service areas: military, education, law enforcement, and public welfare and social services. (For junior high units in other career areas see CE 025 738-765.) (LRA)
