摘　　要：基于多元概化理论,对某次口语测试所包含的朗读、听后回答、回答问题、听后复述四类常见的测试任务进行研究,重点关注不同类型测试任务的区分效果、测量精度和对总分的贡献程度。研究结果表明,偏封闭型、内容导向的测试任务相比偏开放型、技能导向的测试任务,在区分效果、测量精度和对总分的贡献上表现更好。Speaking test tasks,which can be seen as activities that involve a speaker in using language for the purpose of achieving a particular communicative goal in a particular speaking situation,are important parts of the design of a speaking test.Based on Multivariate Generalizability Theory,this study analyzes four common tasks such as reading-aloud,listening-and-answering,answering questions and listening-and-retelling focusing on the effect of differentiation,precision of measurement and contribution to the composite score regarding different tasks.The result of the study shows that in general closed and content-oriented speaking test tasks perform better than open and skill-oriented ones do in terms of the effect of differentiation,precision of measurement and contribution to the composite score.
