Intended for physical education teachers of the handicapped, teacher educators at teacher training institutions, and research workers in areas of the handicapped, the document reports the effects of a theoretical model of teaching psychomotor tasks on the motor behavior of mentally retarded children. Chapter 1 introduces a psychomotor teaching model and offers testing procedures to measure children's motor performance on selected motor parameters, including plantar flexion strength; quadriceps strength; hamstring strength; reaction time (hand/auditory, foot/auditory, hand/visual, foot/visual); balance; sit; and reach. Outlined for each of the motor parameters are the objective, equipment, protocol (task learing and test administration), and scoring. Chapter 2 describes the teaching of stunts and tumbling via a mastery learning psychomotor model. The bulk of the document consists of the entire curriculum of the psychomotor teaching model. A comprehensive evaluation of the psychomotor teaching model is reported in Chapter 3. (SBH)
