摘要
以教育统计与测量理论为基础,根据学生考试原始成绩,从难度、区分度、信度和效度等四个方面给出了对试卷质量分析的数学模型.通过对一个具体的实例分析,应用MATLAB工具根据所给的模型进行了具体的计算,得出试卷质量分析结果,提出了对试卷中试题的修订意见,有助于进一步提高命题的质量,检查教学效果,鉴定教学质量,改进教师的教学方法.
The mathematical models of quality analysis for test papers are given from the difficulty,discrimination,reliability and validity,which are based on educational statistics and measurement theory in order to further improve the quality of the proposition,check the teaching effectiveness,identification of teaching quality and teaching methods.
