THE PLANS FOR A SIMULATION MODEL USING SYSTEMS ANALYSIS AND COMPUTER SIMULATION TECHNIQUES WERE PRESENTED. THE TECHNIQUES AND DESIGN RECOMMENDATIONS WERE INTENDED TO FIND NEW METHODS FOR IMPLEMENTING INSTRUCTIONAL MEDIA. FOUR MAJOR STEPS WERE INVOLVED IN THE PROJECT--(1) SURVEY AND SELECTION OF HIGH SCHOOLS, (2) SYSTEMS ANALYSIS OF FIVE HIGH SCHOOLS SELECTED, (3) CONSTRUCTION OF A COMPUTER-SIMULATION VEHICLE, AND (4) SIMULATION AND STUDY OF THE FIVE HIGH SCHOOLS WITH THE MODEL. THE REPORT CONCENTRATED ON DISCUSSION OF THE CONSTRUCTION OF THE MODEL AND THE SIMULATION STUDY. THE MODEL WAS CONSTRUCTED TO DESCRIBE A SCHOOL IN TERMS OF ITS CHARACTERISTICS AND STUDENT CHARACTERISTICS THAT BEAR ON THE INSTRUCTIONAL PLAN OF THE SCHOOL. PRELIMINARY STUDIES WITH THE MODEL WERE BEING CONDUCTED WHICH INVOLVE THE MODELING ASPECTS OF THE CONTINUOUS PROGRESS PLAN. THIS PLAN WAS DESIGNED TO PERMIT STUDENTS TO PROGRESS AT THEIR INDIVIDUAL RATES. THE REAL TEST OF THE MODEL'S VALIDITY WILL COME WHEN ITS PREDICTED EFFECTS ARE IN FACT CARRIED OUT IN THE SCHOOL ENVIRONMENT. RELATED REPORTS ARE ED 010 559 AND ED 010 577 THROUGH ED 010 581. (RS)
