The intention of a research project was to determine the effectiveness of the Personalized, Individualized, Vocational Occupations Training (PIVOT) materials developed by the School District of Philadelphia in developing entry-level competency in secondary school vocational students. The subject areas selected for the study were industrial electricity, machine shop, and nursing assistant and were taught in skills centers, comprehensive high schools, area vocational-technical schools, and special education occupational schools. Experimental classes using the modular PIVOT materials were taught by means of individual sound-on-slide projectors, while control classes were taught the same subject matter by conventional methods. The rates of success on a criterion task administered by specialists in each field were compared as an indication of the relative effectiveness of the two methods of instruction. The PIVOT method proved capable of developing entry-level competency in each of the areas and settings examined, and the rate of success among the experimental students was not significantly different in any subject area or setting from the rate of success of students taught by conventional methods of instruction.
