Approximately 1800 prospective secondary school teachers at Illinois State University are providing themselves with pre-service education via a self-paced competency-based teacher education program. Called the Professional Sequence (PS), the program replaces courses taught by the lecture method. PS frees students from scheduled classes, eliminates non-essential material, and gives continuous evaluations. The program was developed by selecting the desired competencies and designing self-instructional learning packages consisting of: 1) a proficiency test, 2) a statement of objectives, 3) required and optional learning activities, such as reading, or using tapes or computer-assisted instructional programs, and 4) evaluation. Subject matter is increasingly being prepared for a random-access information retrieval system known as the Program Yielding Rapid Access Major Information Devices (PYRAMID). PYRAMID consists of a series of audio and visual storage and playback systems and a mini-computer control unit. The computerized Surveillance System keeps a master file on each student, recording his completion of learning package activities, evaluating what he has learned, and providing daily and weekly printouts on each individual's progress. Weekly meetings between a student and his advisor allow professors to monitor student progress and provide help as needed. (PB)
