认知诊断测试及其在阅读理解能力上的应用述评

Cognitive Diagnostic Assessments and Their Applications on Reading Comprehension

认知诊断测试是认知心理学和教育测量学相结合的产物,考查学生的个体差异,属于认知水平的研究范式。近年来,随着诊断技术的发展,这一研究方法的优势逐渐凸显,并在语言测试领域得到了广泛应用。本文以认知诊断测试的实施步骤为脉络,回顾了该方法在阅读理解能力上的应用研究,重点讨论当前研究中亟待解决的问题,如理论基础、属性定义、题型选择以及模型的可操作性等。最后,基于这些问题,分析未来研究走向,并对这一方法的应用前景做出展望。

The combination of cognitive psychology and educational measurement contributes to the development of Cognitive Diagnostic Assessment（CDA） which, as an approach of cognitive level paradigm, probes into individual differences of language learners. Since its birth, it has made technological advances on its algorithm through computer simulation, and has applied widely in the context of language testing. This paper, by summarizing the field studies of CDA on reading diagnoses, discovered such problems as the theoretical rationale, the definition of attributes, the selection of items types and the operationalization of statistical models in the current practice. At the end of the paper, future directions have been proposed to illustrate this approach as a useful tool in the broad area of language testing and teaching.
