摘要
本文基于Weir"基于证据的效度验证理论框架",结合教学大纲和考试大纲对听力理解的要求,提出一个针对高等学校应用能力考试A级(PRETCO-A)听力部分的具体效度验证框架。作者依照该框架从五个方面对该测试的效度进行了分析探究。在环境效度方面,从材料长度和朗读速度、话题、听力材料真实性、试题类型等方面进行分析;在基于理论效度方面,对试题所考查的语言知识进行分析;在评分效度方面,从项目分析和内部一致性角度进行讨论;在效标关联效度方面,验证不同年份听力部分成绩之间以及其与CET4听力部分成绩的相关性;在后果效度方面,通过问卷调查对考试的课堂教学反拨效应进行研究。
Based on Weir＇s ＂evidence-based approach to validation＂ and with reference to teaching and testing sylla- bi of listening comprehension, the authors put forward a practical framework tbr the validation of listening section of Practical English Test for Colleges -- Level A （PRETCO-A） from five aspects. Context Validity was analyzed from text length and speech rate, topics and authenticity as well as task type. For Theory-based Validity, language knowl- edge was mainly examined. Scoring Validity was examined through item analysis and internal consistency. For Criteri- on-related Validity, correlation analyses with different versions of PRECTO-A Listening and that with the scores of CET4-1istening were used. As for Consequential Validity, the backwash effect on classroom teaching and learning was explored through questionnaire survey.
