摘要
信度和效度是语言测试理论中的两个重要概念,因为它们是衡量语言测试质量的重要依据。大学英语考试最近一次大规模改革已过去三年,但是国内对新题型的信度和效度研究才刚起步。本文通过实验,用定性和定量的方法对新大学英语六级考试听力测试的信度和效度进行了研究。研究结果表明新大学英语六级考试听力测试的外部信度较高而内部信度较改革前有下滑;内容效度较改革前没有提高而标准相关效度较高。
Reliability and validity are two important concepts in language testing,because they indicate the quality of language tests.After the reform of the CET (College English Test) in 2006,little research on the reliability and validity of CET has been conducted. This paper researches on the reliability and validity of the new CET-6 listening subtest. The results show that the new CET-6 listening subtest has fairly high external reliability but has lower internal reliability than before,and that it has not improved in content va- lidity but its criterion-related validity is fairly high.
