This interim guide develops a new high school option, Lifestyles 205 and provides teachers with a curriculum for a lifestyles studies course for grade 11 or 12. The course includes several major components that emphasize the roles of the developing individual as a producer and consumer and as a family and community member. Major functions of the program are to expand areas of choice, to confirm choice as a normal and valuable human process, and to facilitate changes in student attitudes and behavior. An "Overview" section presents the rationale and lists goals and objectives. The "Implementation" section covers program design for offering lifestyles studies as a full course or as two half-credit courses, teaching methodology, students with special needs, and evaluation. The course is composed of three units: personal development (40 hours), the consumer and producer (40 hours), and interpersonal relationships (40 hours). Each unit is based on major concepts for which are provided student objectives with corresponding content outline and suggested activities. Listings for resource material for each unit are appended.
