西北少数民族地区成就测试信度效度研究

A Study of the Validity and Reliability of Achievement Test in the Northwest Minority Region in China

就大学英语成就测试的质量问题。引述有关现代测试理论对语言测试质量的要求,对4份全校使用的英语成就测试卷进行统计分析,通过与理论标准的对照,发现试卷在试卷内容、试卷内各部分之间的相关系数、试题区分度等方面存在一些问题。这些问题应该得到应有的重视与改进,否则高等教育所给予学生的外语成绩评价就谈不上科学、客观和公正。

To investigate the quality of college-wide tests for non-English majors,four sample of achievement test papers of Ningxia University are analyzed with reference to modern testing theory and associate criteria. A statistical review of the score characteristics from the achievement tests is followed by discussion of aspects like item content, inter-correlation between sections, indexes of difficulty and item discrimination, with a view of bringing strengths and weakness of such achievement tests to the attention of English teachers and test developers, so that corresponding measures can be adopted to improve the test quality
