【摘要】 目的编写及应用计算机考试质量分析程序。　方法用VisualBasic编写自动统计分析程序 ,并对我校15门基础课程的考试结果进行分析。　结果计算机程序能够对记录在Excel文件中的考试成绩进行分析 ,并将考试成绩的排序、最高分、最低分、平均分、分布、标准差以及试卷的信度、各题的难度、区别度等统计结果存入另一个Excel文件中。上述试卷分析表明 :试卷的α信度系数为 0 .73± 0 .11;加权平均难度为 0 .72± 0 .0 9;平均区别度为 0 .2 9± 0 .0 8。结论编写的计算机程序可用于考试质量的统计分析。对于我校基础课程考试 ,可以将平均难度掌握在 0 .7～ 0 .8,信度系数控制在 0 .5或以上 ,平均区别度控制在 0 .2以上或各小题的区别度控制在 0 .14以上。更多还原

【Abstract】 Objective To write a computer program for test quality analysis,analyze the real test items of the course examinations in the program and discuss its results. Methods The Visual Basic was used to compile the program.Examinations of 15 basic courses were carried out and then were analyzed with the program. Results The computer program would analyze the scores in the sheets of the Excel files,sorting orders and finding the max,min,mean,distribution and deviation of the scores,and calculating reliability,difficulty and distinction of the examination.Upon analysis of the 15 examinations,the Cronbach-α coefficients were 0.73±0.11,average difficulties were 0.72±0.09 and average distinctions were 0.29±0.08. Conclusion The program can be used to perform test quality analysis accurately and promptly.It seems acceptable for the examinations of the basic courses at our university to have the criteria set at 0.7 ～ 0.8 for the average difficulty,above 0.5 for the Cronbach-α and above 0.2 for the average distinction or 0.14 for the distinction of each item.更多还原
