摘要:

在网络课程及虚拟课堂中,在线测试是一个重要组成部分。本文对贝叶斯网络及其概率推理进行了简述,提出了基于贝叶斯网络的学生模型,并将其应用于自适应在线测试系统中。该系统不仅能够因人施测,而且具有预测能力,同时还可以排除学生猜对试题答案的非真实能力。

关键词: 贝叶斯网络 学生模型 在线测试系统

Abstract:

Online test is an important part of the network courses and the virtual classroom. Bayesian networks and their probability reasoning are outlined firs tly, then a student model based on Bayesian Networks is proposed and applied to the adaptive online test system, which makes the system feature the abil ity of forecasting and eliminating the random guessing.

Key words: Bayesian networks, student model, online test system
