Three of the more obvious advantages of using a computer to coordinate the logistics of a multifaceted instructional program with large numbers of students are the computer's ability to reliably control student activities, to keep and analyze data, and to make available instructional and evaluative materials. This document describes a computer-based course management system (CAISMS II) and its hardware/software organization as it was developed and implemented on the PLATO IV computer-based instructional system centered at the University of Illinois. The system is intended for courses in community colleges, universities, or military settings. Diagrams illustrating the text are included. (JM)
