摘　　要：通过对项目反应理论在语言测试领域研究成果进行回顾总结,并从单维性、模型拟合、参数分析、信息函数和项目功能差异方面系统地介绍了运用项目反应理论对语言客观试题进行构念效度验证的方法。认为项目反应理论在语言测试领域有广阔的前景和应用价值,并以期为有兴趣利用该理论进行研究的读者提供参考和借鉴。Based on the reviews of the applications of item response theory to language test,this paper systematically presents the way of construct validation based on item response theory for language objective test in terms of unidimensionality,model fit,parameter checking,information function and DIF. A broad application prospect of Item Response Theory applications to language test is discussed in the paper,which enlightens references to the readers who are interested in item response theory.
