摘　　要：为解决高校学生评教量表不规范导致评教指标设置不科学的问题,本文提出采用随机森林算法对学生评教指标建模分析.以程序设计基础课程为例,设计评教问卷,采用随机森林算法建模,对综合评分的优秀与否进行判断,并得到评教指标重要性排序.实验结果显示:教学效果、语言表达等评教指标在高校学生评教量表中占重要地位,对量表的设计改进有重要参考价值.In order to solve the problem of the unscientific setting of evaluation indicators due to the non-standardized evaluation scale of college students,we propose to use the random forest algorithm to model and analyze the evaluation indicators of students.Taking the course“Programming Fundamen⁃tals”as an example,the teaching evaluation questionnaire is designed,and the random forest algo⁃rithm is used to model,compare the measured value and predicted value of the comprehensive scores,and obtain the importance ranking of the teaching evaluation indicators.The experimental results show that teaching effect,language expression,and other teaching evaluation indicators occupy an important position in the scale of university students’evaluation and have an important reference value for the de⁃sign of the scale.
