回归分析在短跑教学中的应用

针对教学中学生100m跑的具体情况,采用逐步回归分析方法建立了回归方程;在此基础上,分别以各相关因素、100 m跑成绩作为因变量与自变量建立了多项式回归方程,并依据正态分布理论制定了各因素平衡发展的标准.上述方法在指导短跑教学中取得了较好的效果.

Application of Regression Analysis to Dash Teaching

In the light of the concrete conditions of teaching students' 100-meter dash, a regression equation is established by using progressive regression analysis. The polynomial regression equations are derived from the above regression e-quation with the interrelated factor and the time of 100-meter dash taken as dependent and independent vaiables respectively. Criteria for equilibrium development of the factors are laid down according to the theory of normal distribution. Satisfactory result is achieved by using the above methods to quide dash teaching.
