Intended for use in training conferences, the manual describes the philosophy and procedures of Try Another Way, an approach for teaching moderately, severely and profoundly mentally retarded persons and developmentally disabled persons difficult to train. An alternative definition of retardation is proposed which stresses level of functioning determined by the availability of training technology. Try Another Way is explained to use task analysis to teach manual tasks to the retarded. The manual covers the following aspects of the approach: task analysis (explanation and an example of teaching a complex assembly task to retarded blind persons); rules for training and reinforcement; a discussion of the concept of influence; and an interview with M. Gold in which he emphasizes the need for systematic training rather than diagnosis. Four training projects and their task analyses are presented (shaking hands, building pallets, washing hands, and folding napkins). The remainder of the manual provides information on publications, films, and training services available from Marc Gold and Associates, Inc. (CL)
