摘要
项目反应理论观察分数核等值方法是一种新的测验等值技术,它整合经典测量理论等百分位等值与项目反应理论观察分数等值两种方法,具有较为优异的测验等值表现。为探讨连续化处理方式在该技术中的作用机制,采用项目反应理论方法与构造伪测验与伪群组方法开展模拟研究,从局部与全域指标角度评价连续化处理方式的表现。结果表明:项目反应理论观察分数核等值方法具有较高的精确性,其系统误差几乎可以忽略不计;采用不同连续化处理方式,其等值结果在分数层面无明显差异,但百分相对误差等局部指标差异较大;采用构造伪测验与伪群组方法模拟得到的数据,其分布符合预期,有效性得到验证。
The item response theory observed score kernel equating(IRTKE)method is a new test equating technique that integrates equipercentile equating in the classical test theory and observed score equating in the item response theory(IRT),and shows excellent test equating performance.In order to explore the effect of continuization methods and bandwidth selection methods,this study used the IRT method and the pseudo-test forms and pseudo-groups(PTPG)method for simulation and evaluated the performance of continuization methods and bandwidth selection methods based on the perspective of local and global indicators.The results showed that the IRTKE method had high accuracy,and its systematic error was almost negligible;the equating results of different continuization methods and bandwidth selection methods had no significant difference at the score level,but there was a significant difference in local indicators such as percent relative error;the data distribution simulated by the PTPG method was in line with expectation and the validity was verified.
