| 摘 要： | RCMLM模型是基于Rasch测量理论的通用拓展模型。利用RCMLM模型对一份普通高中数学试卷进行不同性别的DIF分析。结果表明:该模型可对具有二分计分和多分计分的试题同时进行DIF分析,避免了以往分别对两种计分方式试题进行DIF分析的弊端,保持了试卷的完整性,使DIF分析结果更加有效。

| Abstract: | RCMLM is a general extended model based on Rasch measurement theory.This study uses this model to conduct DIF analysis of college entrance examination mathematics test with different genders.The results show that the model can analyze dichotomous items and polytomous items simultaneously.It not only avoids the disadvantage of DIF analysis for two different scoring methods,but also maintains the integrity of DIF analysis.The analysis results are more effective. |
