试题库系统建设中试题质量分析与建模

The Analysis of the Examination Paper Quality and Model Building on the Construction of the Examination Paper Library

针对现有试题库系统建设中存在的较为普遍的试题质量问题进行了较为深入分析和探讨,对影响试题质量的两个关键因素——难度值和参考分值的确定建立了相应的计算模型,在模型中既考虑了主、客观因素,同时也考虑了实测因素。检验结果表明,所建立的关于难度值和参考分值计算模型能够很好地表达试题库系统中的试题质量。

This article analyses and explores the more common quality problems of the examination paper on the construction of the examination paper library. It also builds relative calculate model to the two key factors which affect the quality of examination paper： difficult value and reference value. Not only subjective and objective factors but also actual test factors are considered. The results of the experience show that calculating model of the difficult value and reference value can better illustrate the quality of the examination paper on the examination paper library.
