摘要
选择题是许多大规模标准化考试中广为使用的题型。为了保障选拔性考试的测量信度、效度和公平性,题目的区分度必须得到保障。文章对选择题及其区分度估计的经典测验理论和项目反应理论方法做了详细讨论,并从命题和测量学分析两个角度提出了一些提高区分度的具体建议。
Multiple-Choice items are widely used in many large-scale standardized tests. In order to provide a fair,reliable and valid assessment,differentiating test takers effectively is essential for any norm-referenced tests. The concepts and estimation methods of discrimination index or parameter are discussed in great detail based on both classical testing theory and item response theory. Suggestions on improving item discrimination are provided from the perspective of item development and psychometric analysis.
