In developing a tutoring system, one of the most difficult tasks is to collect tutoring knowledge from multiple educators, especially courses in which the contents change frequently, due to the advent of new technologies. We propose a Web-based intelligent tutoring strategy construction system, which is able to elicit, analyze, and integrate tutoring knowledge from multiple educators systematically. Experiments on two courses have been performed to evaluate the time, completeness, and accuracy improvement in constructing tutoring knowledge bases with our approach. According to the experimental results, it can be inferred that for most cases, our approach achieves desirable performance.
