Five PLATO exercises on linear decision models were developed to investigate the feasibility of teaching material from operations research on the PLATO computer-based education system. The exercises were administered to business administration students enrolled in an introductory course in operations research. Each PLATO session was monitored to observe student reactions and performance, and questionnaires and an attitude survey were administered. Results indicated that it is technically and operationally feasible to teach subject material in operations research on the PLATO system, but this teaching medium is costly. Students favored this teaching medium and learned the material as well or better on the PLATO system. A shorter time was involved using the computer than using traditional teaching materials. Attributes of computer-based systems were also derived from the study. (CH)
