One of seven booklets on Special Olympics Sports Skills Instructional Programs, this guide presents an instructional program for volleyball coaches working with mentally retarded persons. The instructional program presents information on the following topics: long term goals; short term objectives; modifications and adaptations of equipment, sport rules, and playing areas; sports skill assessments (criterion referenced measures to determine the student's present functioning level within the sport or skill); teaching skills; skill sequence; task analyses; teaching suggestions; an infusion chart that relates the sports skill to general academic areas; student skill chart for marking the student's sports skill performance throughout the program; and terminology and resources. Volleying, serving and spiking, and defensive skills are presented for two levels of volleyball skills. Additional sections focus on team tactics, rules, and sportsmanship. (CL)
