An intelligent computer aided instruction system for plant operators to study emergency procedures

Abstract

Intelligent CAI system has been developed which makes it possible to provide consistent education in plant operation and also plant behavior for professionals like shift supervisors. Satisfaction of intrinsic motivation was tried by representing instruction according to the learners' level. The student model, which is common to teaching course for presenting text knowledge of emergency procedures and the indicating course for actual plant behavior and procedures using the plant simulator, was derived from a hierarchical function model which is a goal oriented mental model of a plant operator. The understanding level of each node (element of a function) in the model is evaluated by personal history conditions calculated from both the tutoring record of the node and the understanding level of the connecting nodes.
