基于教育测量理论的数学学业测试卷质量评价

The Quality Assessment of Math Test Paper based on the Educational Measurement Theory

本文利用经典测量理论(CTT)和项目反应理论(IRT),对用于我国民族地区义务教育数学学业水平测试的试卷质量进行了质性和量化分析,并对CTT和IRT得出的部分结果进行了对比分析.结果表明,测试卷质量总体良好;IRT具有项目参数和被试能力参数不变性的特征,能更加真实全面地反映出学生的能力水平.

In this paper,the classical test theory（ CTT） and item response theory（ IRT） were used to do the qualitative and quantitative analysis of the papers quality for the mathematics achievement levels tests in ethnic regions of China. The results showed that the test paper quality was generally good; IRT had the invariant features of item parameters and ability parameters; IRT can reflect the ability level of students.
