Variations of backward chaining--backward chaining with leap-aheads (BCLA) and reverse chaining with leap-aheads (RCLA)-- were compared with four severely retarded learners (17-32 years) who were trained on two complex vocational tasks. Learning rate for the BCLA procedure was superior to the RCLA procedure. Time to criterion differences were…

The characteristics of the skill clusters involved in community living response chains were studied, focusing on the length of the chain, the response classes contained in the chain, and the implicit variations within the chain. Instruction of response chains can be enhanced through consideration of the stimulus control strategies used.…

In a study which taught four high school students with severe handicaps to use a commercial washing machine and laundry soap dispenser, a concurrent chaining strategy was found more efficient than forward chaining in facilitating skill acquisition. Concurrent chaining also resulted in better maintenance at four- and eight-week follow-up…

Three adolescents with moderate mental handicaps were taught bedmaking skills through a technique which involved dividing the entire chain into sections, teaching the first section in a total cycle fashion, and adding instruction on subsequent sections in a forward chaining manner. The technique promoted skill acquisition and substantial…

The article provides guidelines and examples for developing individualized instructional programs in either concept development or motor skill development for moderately and severely handicapped learners. (DB)

Whole task training and graduated guidance were used to teach independent dressing skills to two developmentally disabled 4-year-olds. After the boys acquired basic dressing skills, additional practice (fluency training) elevated their performance to socially validated rates. Follow-up showed that the skills were maintained and generalized to…
