用数学模型评价试卷质量

Apply Mathematical Model to Evaluate Quality of Test Paper

讨论项目反应理论的３个主要数学模型，用实例说明如何应用项目反应理论来评价试卷质量，并把所得结果与经典项目分析作比较．

In this paper, the three main mathematical models concerning item response theory are being discussed. The method of using item response theory to evaluate the quality of a test paper by real example is illustrated. Hence the results from this method are compared with those from classical item analysis.
