摘要
针对高校学生评教系统中的各项指标得分,提出一种基于二进制信息粒的学生评教数据分析方法。该方法用二进制信息粒表示指标得分,根据粒中"1"出现的个数快速获得班级学生对指标分值的支持度,计算出教师在各指标上的平均得分,并进行排名。利用二进制信息粒的表示获得各班级各指标平均分的排名累计平均,结果简单、直观,并且可以获得学生对教师不同指标的评价细节,以便教师根据评教数据分析结果改进课堂教学质量。
According to the scores of university teaching evaluation indices, a data analysis mathod of students＇ evaluation of teach- ing results based on binary information granule is presented. Firstly, the scores of teaching evaluation indices are mapped to binary infor- mation granules, then the number of 1 in the granule is counted to obtain a class students＇ support degree. Secondly, the average of each index is calculated and sorted to obtain the ranking of each index. Finally, the ranking cumulative average of all classes of the same teacher on each index is obtained according to the method of binary information granule. The result is simple and intuitive, and the detail of students＇ evaluation of teaching can be revealed ,which has important significance in improving teaching quality.
