基于决策树算法的学生体质健康促进政策执行评价研究

Research on the implementation evaluation of students’health promotion policy based on decision tree algorithm

采用问卷调查法等,基于国家学生体质健康促进相关政策的具体要求,调查中学生体质健康促进政策执行的基本现状,并使用决策树法构建评价模型,为政策执行提出优化建议.结果发现:中学生体质健康促进政策执行现状总体评价较好,执行好表现在9个方面,执行差表现在7个方面;学生参与冬季长跑活动情况、眼保健操情况和学生对政策了解程度对政策效果影响较大,但执行过程中存在偏差,应给予重视和加强.

Based on the specific requirements of the national policies on promoting students’physical health,this paper investigates the basic status quo of the implementation of the physical health promotion policies for middle school students,and uses the decision tree method to build an evaluation model,so as to put forward optimization suggestions for the implementation of the policies.The results show that:the overall evaluation of the implementation of the policy is good,good performance in 9 aspects and poor performance in 7 aspects;students’participation in winter long-distance running activities,caring eye exercises and students’understanding of the policy have a great impact on the policy effect,but there are deviations in the implementation process,which should be attached great importance and strengthened.
