A SYSTEMS ANALYSIS WAS MADE OF A 10TH-GRADE SOCIAL STUDIES COURSE IN AMERICAN HISTORY TAUGHT AT THE NOVA HIGH SCHOOL, FORT LAUDERDALE, FLORIDA, TO EVALUATE THE COURSE AS AN INSTRUCTIONAL SYSTEM. THE ANALYSIS WAS CONCERNED WITH SUCH PROBLEM AREAS AS TEACHER ROLES, THE EFFECTS OF MEDIA ON STUDENT-TEACHER RELATIONSHIPS, INFORMATION REQUIREMENTS, THE USE OF SPACE, AND THE EFFECTS OF COURSE PROCEDURES ON STUDENTS. A COMPUTER SIMULATION MODEL OF THE COURSE WAS SET UP AND TESTED. DATA PRODUCED BY THE MODEL WERE COMPARED TO DATA THAT WERE DESCRIPTIVE OF THE COURSE. THERE WAS A HIGH DEGREE OF CORRESPONDENCE BETWEEN THE SIMULATED DATA AND THE DESCRIPTIVE DATA, INDICATING THAT THE SIMULATION PROCEDURES WERE EFFECTIVE IN PRODUCING DATA THAT APPEARED TO BE VALID. RELATED REPORTS ARE ED 010 568 AND ED 010 569. (GD)
