用数理模型对体育分组教学进行预测与控制

为了使身体条件不同的学生在体育课中得到一定的锻炼效益,促使体育教师从多方面考虑和研究如何进行体育分组教学,以遵循“区剐对待”的教学原则,对不同情况的对象给予相应的指导,做到使体育优等生和体育差生的身体素质同步向前发展。在体育教学改革中实行体育“优生”和“差生”的分类教学,那么如何将学生分类呢?本文采用建立数理模型进行数值预测,计算出预测值与控制常数,从而达到对不同体育程度的学生进行分类,为广大教师提供切实可行的方法和科学依据。

A Prediction and Control Method for Grouping Teaching Based on a Mathematical Model

To gain benefit for every students with different physical status in their physical education class, a teacher should be given his teaching and training in grouping manner. Based on the physical status difference of the students, at least two groups, "excellent" and "average" groups, should be tak-en, with each being taken different teaching methods and with different requirements. In this paper, a mathematical model for how to group the student is suggested. The model can yield the threshold for the optimal classification. It therefore can be used for teacher to organize physical teaching procedure more effectively.
