A study was conducted to determine whether or not the Personalized, Individualized, Vocational Occupations Training (PIVOT) materials developed by the School District of Philadelphia were capable of developing entry-level competency in secondary school students in a variety of educational settings (comprehensive high schools, an occupational school for educable mentally retarded, a skills center, and an area vocational-technical school) and subject areas (nurse's aide, industrial electricity, automotive mechanics, and machine tool trades). Experimental classes, using the PIVOT materials, were taught by means of individual sound-on-slide projectors, while control classes were taught the same material by conventional methods. Comparison of rates of success on a criterion task in each subject area proved the PIVOT method capable of developing entry-level competency in each setting. No significant differences were detected however between effects of the PIVOT materials and conventional methods except for educable mentally retarded students, who learned significantly better with the PIVOT materials. Repetition of the experiment with larger groups of students is recommended. Appendixes, which comprise three-fourths of the document, include lists of PIVOT units, the criterion tasks and checklists for units used in the research, the rating form for individual slides and definitions of possible defects, samples of printed materials used with the PIVOT units, and the research questionnaires.
