评价语言测试质量的三种理论模型对比研究

A Comparative Study on Three Theoretical Models for Evaluating the Quality of a Language Test

评价语言测试质量的三种理论模型,即经典测验理论、概化理论和项目反应理论的基本内容和假设基础,分别从理论基础、题项分析方法等方面讨论了三种理论的优缺点,为语言测试质量评价理论模型的合理选择提供了依据。

The basic concepts and hypothesis bases of three theoretical models, namely Classical Test Theory, Generalizability Theory and Item Response Theory, for evaluating the quality of a language test were introduced in the paper. The advantages and disadvantages of three models were discussed from the perspectives of the hypothesis basis and item analysis method, which provided a guide for the proper choice of theoretical models in evaluating a language test.
