Forward and Backward Chaining, and Whole Task Methods

Abstract

The effects of training by whole task, forward chaining, and backward chaining methods were examined in teaching vocational rehabilitation clients the construction of three assembly tasks. Clients learned to assemble a bicycle brake, a meat grinder, and a carburetor on three successive days by the three training methods in a counterbalanced design. The percentage of responses that were errors was, on the average, more than twice as great for subjects in the whole task method as for subjects in either chaining method (which did not differ). Total time to criterion did not differ among chaining and whole methods. Slower learning subjects benefited substantially from the systematic chaining procedures.
