具有自适应特征的在线考试系统的研究与应用

摘要

自适应考试系统能有效测出应试者的真实能力水平，但题库质量要求高，试题参数计算复杂，系统实现有一定难度。具有自适应特征的在线考试系统能够以知识点相关联，融合两种考试方式的优点，实现对应试者真实能力水平的考查。文章对初始选题、自适应选题策略、终止规则等关键技术进行了研究，实验表明该系统测试效果较好。%The adaptive test system can effectively measure the real ability of the candidate, but the quality requirement of the test bank is high, the calculation of the test parameters is complex, and the system realization is difficult. An online test system with adaptive features can be related by knowledge points, and can integrate the advantages of the two test methods, to realize the examination of the real ability of the candidate. In this paper, the key technologies are studied, including the initial question selection, adaptive question selection strategy and selection termination rules. The experimental results show that the system has a good examination effect.
