VARIOUS ASPECTS OF THE DEVELOPMENT AND USE OF SELF-INSTRUCTIONAL MATERIALS WERE REPORTED. MATERIALS WERE DEVELOPED TO COVER 6 WEEKS OF INSTRUCTION IN THE SECOND SEMESTER OF HIGH SCHOOL PHYSICS. APPROXIMATELY 3,000 INDIVIDUAL QUESTION-AND-ANSWER FRAMES WERE INCORPORATED INTO THE MATERIALS. TO DETERMINE THE CONTRIBUTION OF THE MATERIALS TO STUDENT ACHIEVEMENT, COMPREHENSIVE EXAMINATIONS COVERING NINE INSTRUCTIONAL UNITS WERE CONDUCTED. THE SUBJECTS CONSISTED OF APPROXIMATELY 450 STUDENTS IN 15 HIGH SCHOOLS WHERE PHYSICS FILMS (TELECAST DAILY OVER EDUCATIONAL TELEVISION STATIONS IN PITTSBURGH) WERE USED REGULARLY. COMPARISONS OF RESULTS WERE MADE OF CLASSES WHICH RECEIVED THE SELF-INSTRUCTIONAL MATERIALS, SUPPLEMENTING THEIR REGULAR PHYSICS COURSE, AND THE CLASSES WHICH RECEIVED ONLY CONVENTIONAL INSTRUCTION. THE PRELIMINARY RESULTS INDICATED THAT SELF-INSTRUCTIONAL MATERIALS MADE A SIGNIFICANT CONTRIBUTION TO THE LEVEL OF ACHIEVEMENT ATTAINED BY THE SUBJECTS. FURTHER PLANS OF THIS PROJECT WERE SUMMARIZED. RELATED REPORTS ARE ED 003 205 THROUGH ED 003 207, ED 003 214, ED 003 215, AND ED 003 655 THROUGH ED 003 659. (RS)
