摘要
考试质量的评价是当前教育和考试研究领域的一个重要课题。其中，对试卷和试题的定量评价是考试质量评价的重要基石。本文以高考北京卷的全总体统计分析为基础。从实证的角度出发。提出基于数据的高考试题质量评价标准。主要涉及试题的难度、区分度、选项分析、有效分数区间及分值利用率等方面。分析结果表明，对大规模教育考试试卷与试题的质量评价．要考虑考试类型、学科、题型、分值权重等因素。要根据考试的科目、题型设定不同的难度标准：评价区分度要考虑其分值权重，对选择题可以进一步分析其选项；对多值计分题可以进一步考察其有效分数区间和分值利用率。
The evaluation of examination quality, which primarily bases on the quantitative analysis of examination papers and items, has become an important issue in the field of examination research. The standards for evaluating the items have been proposed in this article on the basis of the analyzing of the data collected during the past 5 years in the College Entrance Examinations in Beijing. The standards mainly concern difficulty index, discrimination index, analysis of item alternatives, effective score interval and score efficiency. The result suggests that as to the evaluation of large-scale educational examination, a few factors should be taken into account. These factors include the examination type, the item type, the subject, and the score weight. The standards for difficulty should be based on the subject and the item type. To evaluate the discrimination, the score weight should be taken into account. The analysis of item alternatives will help to understand the inner mechanism of the items, so does the analysis of effective score interval and score efficiency of the constructive items.
