SYSTEMS ANALYSIS AND COMPUTER SIMULATION TECHNIQUES WERE APPLIED IN A STUDY OF THE ORGANIZATION OF A BIOLOGY COURSE FOR INDIVIDUAL PROGRESS. THEODORE HIGH SCHOOL AT THEODORE, ALABAMA, WAS SELECTED FOR STUDY BECAUSE OF ITS APPROACH TO THE ORGANIZATION OF ITS RESOURCES FOR STUDENTS TO LEARN ON AN INDIVIDUAL BASIS. DESCRIBED IN THIS INTRODUCTORY REPORT WERE (1) SCHOOL ENVIRONMENT, (2) PERSONNEL, (3) OBJECTIVES, SPACE, AND FACILITIES, (4) USE OF INSTRUCTIONAL MEDIA, AND (5) ORGANIZATIONAL FEATURES. THE SPECIFIC PROCEDURES FOLLOWED IN INDIVIDUALIZED INSTRUCTION WERE EXAMINED BY FOCUSING ON THE BIOLOGY COURSE ORGANIZATION. THE COURSE HAD BEEN ORGANIZED FOR INDIVIDUAL PROGRESS AND USED A STUDY GUIDE TO DIRECT THE WORK OF STUDENTS. A DETAILED DESCRIPTIVE ANALYSIS WAS PRESENTED IN THE SECOND OF A SERIES OF THREE REPORTS REFERENCED ED 010 566. THE RESULTS OBTAINED BY COMPUTER SIMULATION OF EXPERIMENTAL MANIPULATION OF THE ORGANIZATION OF THE COURSE WERE REPORTED IN ED 010 567. (RS)
