摘　　要：传统的网络考试组卷算法由于仅仅考虑考试范围,以及试卷整体难度系数,而从不考虑应试者的能力水平,从而造成生成的部分试卷无法有效地达到测试应试者能力水平的效果。项目反应理论作为一种现代心理测试理论,在评估应试者能力水平方面具有广泛的应用。本文基于项目反应理论设计了一种能充分考虑应试者能力水平的组卷算法,从而使得组成的试卷能够达到命题老师的预期效果。实际应用结果也表明,该算法是非常有效的。With the traditional network test paper generating algorithm,the scope and the overall diffculty coeffcient of the test paper are the major considerations,but the ability of the examinee is neglected.Consequently,some generated test papers fail in assessing the examinee＇s ability.The item response theory,as a modern psychological testing theory,has been widely applied in assessing the ability of examinees.Based on the item response theory,the paper designs a test paper generating algorithm with a full consideration to the ability of examinees,so that teachers can achieve the expected effect with the generated papers.The practical application results show that the algorithm is very effective.
