HSK题目参数的相对稳定性实证研究

An Empirical Research on the Relative Stabilization of HSK Item Index over Different Circumstances

目前汉语水平考试(HSK)的数据分析,采用的是经典测验理论.通过这种分析技术所得到的题目参数会随着样本的变化而变化。本研究以相同的题目在不同时间、不同地点对不同的被试群体施测获得的题目参数为研究对象,探讨题目参数的变化幅度、引起变化的因素以及变化的内在规律。

We use the Classical Test Theory to analysis the HSK items regularly. However, the result we get is not perfect,for it relies seriously on the examinee sample we choose. This paper presents the index of item discrimination＇ range variation of the same item,over the different testing time, different more.the paper accounts for what testing places, and different examinee sample. Further cnusa the variation and its internal regular pattern.
