摘要
应用拉格朗日乘数法建立学生体质最大化模型,通过模型分析得出结论:体质下滑不是学校体育的责任,学校体育也无法独立承担提高体质的重任;在应试教育背景下保障学生体质的有效办法是使所有学生体育锻炼的机会成本大体相等。
Using Lagrange function to establish the max-physical fitness mode,and by analyzing the mode,some conclusions are deferred： PE shouldn＇t be blamed for the students＇ fitness decline,and the best way to make sure that students will exercise is to have the almost same opportunity cost for their exercise.
