Designed for instructors participating in a workshop on the use of the Personalized System of Instruction (PSI), this packet of materials examines the systems approach to classroom instruction, looks at the components available for PSI use in Somerset County College's Mathematics Laboratory, reviews the procedures currently in use in the Math Lab, and considers successful PSI programs and instructional problems. Following material on the rationale for and goals and objectives of the workshop, an overview is provided of systems approaches in education and the role of the instructor in PSI. Next, an outline is presented of the human, printed medium, and audio-visual components of PSI that are available in the Math Lab or are available upon request. A brief overview of PSI is followed by a more detailed outline of its five fundamental characteristics: (1) the stress is on the written word; (2) near perfection is required on each unit before the student can progress to the next unit; (3) students proceed as rapidly as they can and still maintain virtual mastery of course content material; (4) lectures and demonstrations are used as vehicles of motivation rather than sources of critical information; and (5) peer tutors, or proctors, evaluate student work immediately and supply personal tutoring, counseling, and encouragement. Comments on classroom management and the final examination are followed by a brief description of the use of PSI in the Dallas County Community Colleges. (AYC)
