摘　　要：大学生培养方案设计、课程排课及教师工作量评估等工作都需要对不同课程的难度进行比较.引入成对比较法,对在校学生进行课程难度问卷调查,分析统计结果给出不同课程的难度排序及分组.在调查表中,每名学生对10门课程进行两两比较,选出相对较难的课程.在数据分析时首先筛除具有循环误判(即A比B难,B比C难,C又比A难)的调查数据;其次检测多个被访者对10门课程难度系数的评估是否有相同倾向;最后在得出一致性倾向显著的基础上,结合Friedman检验、Page检验及Hollander-Wolfe比较给出不同课程的难度系数排序及分组.Evaluation of the course difficulty is the basis of a lot of works as follows: college students' training scheme design,curriculum schedule arrangement and teachers ' workload evaluation. An evaluation method of the course difficulty based on paired comparison is proposed in this paper. This method contains questionnaire and data analysis. In questionnaire part,test subjects compare two courses and select out one considerably difficult course. The data analysis stage has three parts. Firstly,filter out the circle error data from survey data. Circle error data happens when course A is considered more difficult than course B,course B is considered more difficult than course C and course C is considered more difficult than course A. Secondly,check whether the test subjects,on average,have equal preference to the tested courses. Luckily,a strong agreement is obtained in this paper. Thirdly,sort and group the courses according to their difference in difficulty by the Friedman test,the Page test and the Hollander-Wolfe comparison method.
