Study on key technology of practicing the operation of automatic evaluation system in the whole simulation environment

摘要

Because of the traditional assessment cannot reflect students’ practical skills in a fair, objective and efficient way, this paper suggests to build the auto-evaluation system, highlighting the key technologies and the different ways to implement it, which includes the scoring algorithm, tracking and playback of the operation process, QTI standards-based operating questions standardization and so on. The computer-assessed examination offers a feasible way to evaluate students’ practical capabilities in a fair, comprehensive and objective way.
