Qualitative Simulation and Intelligent Tutoring Aids for Training in the Operation of Complex Dynamic Systems
Abstract
Supervisory control operators of complex dynamic systems must possess thorough knowledge of the systems, and skills to apply this knowledge to maintain system operation. Use of intelligent tutoring systems (ITS) can be economical for training such operators. An ITS can help organize system knowledge and operational information and also provide practice to develop appropriate skills. The ITS is comprised of a simulated power plant, the tutor, and mouse-based direct manipulation graphical interfaces. The ITS was experimentally evaluated using Naval ROTC cadets as subjects under three training conditions: (1) simulator only, (2) a passive tutor that provided help upon request and without intervention, and (3) an active tutor with intervention. Performance in all three conditions was analyzed in identical data collection sessions. Performance measures such as percentage of premature and correct diagnosis of relevant and irrelevant diagnostic test were used. Experimental results show that a simulator alone is inadequate, whereas a simulator in conjunction with an ITS can help develop efficient trouble shooting skills. However, not all students are equally receptive to every tutoring strategy and provisions must be made in training programs for individual preferences and differences in abilities and styles.
