SYSTEMS ANALYSIS AND COMPUTER SIMULATION TECHNIQUES WERE APPLIED IN DESCRIBING THE BIOLOGY COURSE AT THE THEODORE HIGH SCHOOL, THEODORE, ALABAMA, WHICH WAS SELECTED AS THE UNIT OF STUDY BECAUSE OF ITS ORGANIZATION OF COURSES FOR INDIVIDUAL PROGRESS. A DESCRIPTIVE ANALYSIS OF THE BIOLOGY COURSE WAS PRESENTED IN TERMS OF THE (1) INSTRUCTIONAL MEDIA, (2) PROCEDURES, (3) ROLES OF PERSONNEL INVOLVED IN THE COURSE, AND (4) SPACE USED. A STUDY GUIDE USED TO DIRECT EACH STUDENT THROUGH THE COURSE WAS ANOTHER INNOVATIVE FEATURE OF THE COURSE ORGANIZATION. THE STUDY GUIDE CONSISTED OF A DETAILED PLAN OF THE COURSE AND INSTRUCTIONS FOR STUDENTS. THE COURSE WAS DIVIDED INTO THREE LEVELS OF PERFORMANCE--(1) HIGH APTITUDE, (2) MEDIUM APTITUDE, AND (3) LOW APTITUDE. STUDENT ASSIGNMENT, PERFORMANCE, AND COURSE CHARACTERISTICS WERE DESCRIBED. RELATED REPORTS ARE ED 010 565 AND ED 010 567. (RS)
