This paper describes a language-based, problem-solving socialization and sex education curriculum designed for individuals with developmental delays. The curriculum aims to increase the students' understanding of themselves socially, psychologically, and physically enabled to function more effectively in a mainstream society that is ever changing. The program has a strong theoretical and applied research base in the areas of language development and thought, sociolinguistics, and cognitive behavior modification. It uses a process-oriented approach involving group interaction and natural context. This paper describes the program's philosophy, parental permission needed, student attitudes, and use of team teaching. Activities include vocabulary development; use of pictures, slides, and videotapes; semantic mapping; role play; problem solving; group work; and follow-up activities. The curriculum's 31 lessons cover such topics as hygiene, human reproduction, relationships, acquired immune deficiency syndrome, and sexual abuse. A sample lesson plan is presented, on the topic of parts of the body. (Contains 32 references.) (JDD)
