This project was primarily concerned with the preparation, development and refinement of programed material in prevocational and work-related areas for use with the Devereux Model 50 Teaching Aid and other auto-instructional aids that are readily available throughout the country. A secondary goal was the evaluation of the effectiveness of using programed instruction in vocational training of adolescents with moderate intellectual and/or emotional handicaps. Four teaching methods used included the: (1) Automated Method, (2) Conventional Method, (3) Integrated, and (4) Programed Lecture. The most effective of the four methods proved to be the integrated method, while the automated method was more efficient than the conventional and the programed lecture methods. Students who were taught by the machine method alone, demonstrated the weakest performance on proficiency tests. A final conclusion was that the training of mentally retarded and emotionally handicapped adolescents can be enhanced through a coordinated program of good teaching instruction and programed instruction.
