语言测试的社会公平性问题的实证研究——汉语水平考试的DIF检验

任何一种测试都要公平、公正,否则就失去了它存在的价值和意义。对语言测试的公平性问题的研究是测验开发者不可推卸的责任和义务。汉语水平考试(HSK)是专门为汉语作为第二语言的学习者而设计的语言测试。经过二十多年的发展,HSK在公平性问题研究方面已经取得了长足进展。针对HSK特有的考生构成特点,本文将考生数量较少的非亚裔考生当作研究对象,将其设为目标组,考察HSK是否会对这个亚群体考生不公平。在此运用三种传统的DIF检验方法——MH方法、SIBTEST方法和Logistic regression方法,对HSK【初中等】一套试卷的听力理解测验进行DIF检验,比较目标组(非亚裔考生)和参照组(亚裔考生)在同一组项目上的表现。

Through three traditional DIF detecting methods,we eompared the performance between the focal group and reference group in one of HSK listening test.
