摘要
对高校学生网上评教存在的主要问题进行了分析,给出了网上评教的信息处理新方法.首先利用信息熵和正态分布函数对学生可信度函数进行了定义,再根据可信度大小对学生评价的权重进行了分配,最后利用加权算术平均算子对课程班的得分进行集结.数值算例分析了方法的有效性、合理性和可操作性.
This paper is devoted to propose a new information processing method to solve the main problems of university students＇ evaluation of teaching quality.By using the information entropy and normal distribution function,we first define a new function of students＇ reliability and give the students＇ weights of evaluation according to the data of reUability,and then calculate the score of the teaching quality by the weighted arithmetic averaging operator.Finally,an example,which shows our method is effective,reasonable and feasible,is given.
