题组DIF检验方法在HSK(高等)阅读理解中的应用

Using Testlet DIF Procedures to Detect Testlet DIF in Reading Test of HSK(Advanced)

本研究引入能够处理题组效应的项目功能差异检验方法,为篇章阅读测验提供更科学的DIF检验法。研究采用GMH法、P-SIBTEST法和P-LR法对中国汉语水平考试(HSK)(高等)阅读理解试题进行了DIF检验。结果表明,这三种方法的检验结果具有较高的一致性,该部分试题在性别与国别变量上不存在显著的DIF效应。本研究还将传统的DIF检验方法与变通的题组DIF检验方法进行了比较,结果表明后者具有明显的优越性。

This study introduces the procedures of testlet DIF and aims to produce more sound methods for passage -based reading tests. The study uses GMH, P -SIBTEST, P- LR to detect testlet DIF for the reading tests of HSK（advanced）. The results of the three methods are consistent. The study indicates that there is no significant DIF for different gender groups and national groups （ the foreigners-v, s. -the minorities in China）. Compared with the non - testlet DIF procedures, the testlet DIF procedures are more technically sound for reading tests.
