基于效度整体观的中国高校大学英语

分级考试效度研究

—以上海理工大学 2013 年分级试卷为

例

摘要

语言测试是教育心理测量界的重要概念，其中的一种重要形式即为分级考试。

分级考试可以把不同语言水平的学生编入相应的教学环境学习以期达到合理分配

教学资源、提高教学效果的目的。国内大学通常要求大学新生参加大学英语分级考

试，了解其英语水平，根据英语能力将新生分入不同的班级，配置与级别要求一

致的教师，学习相应的教材，提供多样的教学计划等，从而最大程度上发挥学生

的语言能力。由此，分级测试对大学生的四年英语能力的提高至关重要。因此，在

设计大学英语分级考试时，设计者更须关注该类考试是否具有效度。然而，国内

缺乏对该类考试具体实施效果的研究，更鲜见基于理论对分级考试进行的效度验

证。

上海理工大学（USST）于 2012 年开始实施新生大学英语分级考试

（CEPT），以为该校大学英语分级教学提供参照标准。为提高该校分级考试的设

计，作者对 USST CEPT 2012 进行效度验证。结果表明该分级考试整体上具有效度

但是仍有提高之处。借鉴 USST CEPT 2012 效度验证经验，作者更全面地对 USST

CEPT 2013 进行效度验证，以探究修正后的 USST CEPT 2013 是否在效度方面与

USST CEPT 2012 保持一贯性。

本文采用 Messick (1989) 提出的效度整体观作为研究的主要理论基础。众所周

知，效度整体观在语言测试界产生了重要影响，获得众多语言测试学者的认同。

正如 Bachman (2004: 259) 所赞：“当代教育心理测量界所遵循的效度理论概念要

得益于 Messick 的贡献，其思想对北美及以外的国家的测试学皆产生了重要影

响。”此外，本文还借用 Bachman 和 Palmer (2010) 任务特征框架以及 Weir (2005)

提出的基于证据的效度验证，通过将该两个理论的部分内容融合进效度整体观，

作者提出 USST CEPT 2013 效度验证框架。该理论框架由五部分构成，即构念效度

内容效度、校标关联效度、表面效度和后效效度。

研究结果表明，USST CEPT 2013 具有很高的构念效度，一定的内容效度、表

面效度和后效效度，但是校标关联效度比较低，总体来说可以保证根据分级考试

成绩学生可以被分入相应的级别。同时在研究的过程中，作者也发现了该考试存

在一些不足，并提出了改进的建议，以提高 USST CEPT 的效果进而促进该校大

学英语教学。

ABSTRACT

Assessment is a crucial concept in fields of educational and psychological

measurement. One of its types, placement test, is frequently used in language teaching

to group students with various proficiencies into different classes. Chinese college

freshmen are generally asked to attend College English placement test (CEPT) with the

aim to be distributed into appropriate learning classes, equipped with particular teachers

and materials, provided with diverse teaching plans according to actual language levels

so as to optimize their learning abilities. There is no doubt that CEPT can influence their

English learning in four years. Thus, test developers should pay attention to its proper

difficulty level and representativeness. However, it was found that researches on

implementation results of CEPT are rarely carried out in China, let alone validation

study based on a theory in this field.

In 2012, University of Shanghai for Science and Technology (USST) began to

implement CEPT in order to provide reference for English placement teaching. To

improve its design, the validity of USST CEPT 2012 was investigated. Results show

that it is valid as a whole, but some parts can be developed better. Referring to

experience in validating USST CEPT 2012, the validity of USST CEPT 2013 is

analyzed more comprehensively to observe whether the test has consistent validity.

Unified concept of validity of Messick (1989) is mainly served as the theoretical

foundation. Messick’s idea about validity is influential in language assessment and

obtains agreement of many scholars later. As Bachman (2004: 259) eulogizes, “the

theoretical conceptualization of validity that conducts current practice in educational

and psychological testing in many parts of the world is largely due to the idea of Samuel

Messick. It has a strong influence on current measurement practice in North America, as

well as in countries outside of North America.” Besides, the framework of task

characteristics by Bachman & Palmer (2010) and Weir’s evidence-based approach for

validation (2005) are also used to some extent. Some of their theoretical content is

integrated in the unified concept of validity. And finally, a new research framework is

proposed to investigate the validity of USST CEPT 2013 from five aspects including

construct validity, content validity, criterion-related validity, face validity and washback

validity.

Through analysis, the author concludes that the validity of USST CEPT 2013 can

be ensured to some extent in construct, content, face and washback but not promised in

criterion-related aspect. Thus, it can be said generally to differentiate students of

different English levels so that they can be distributed into appropriate learning

environment. Finally, the author puts forward some weakness in the test and provides

suggestions for improving the design of future USST CEPT so as to further advance

College English teaching of USST.
