The design and implementation of general tutor system for multi-disciplinary courses in virtual experiment

Due to the problem that students can't get teacher's guide timely in virtual experiment, we have designed the tutor model based on virtual experiment and implemented an intelligent tutor module with rules engine technology, according to the habits of thought when students perform experiments. This module could provide instructional message to students during experiment process. It extends the knowledge base of intelligent tutor system (ITS), also improves the integrity and flexibility of the guidance function. In this paper, we take the circuit analysis virtual experiment as an example, and then discuss ideas of the design, key technology and the implementation technique.
