自古以来,非优思想在人类的认识史上就占有非常重要的特殊地位,人们从来都很重视从失败中吸取教训.在体育教学实践中,不仅以追求优化的过程和结果为目标,而且力求避免落入非优或失败的境地。依据系统工程学的有关理论,我们可以把体育教学系统抽象为一定的模型,在满足约束条件的情况下,以求得体育教学系统整体的最优解。但是,由于体育教学实践的高度复杂性,例如,存在众多的未知因素和不确定因素,教与学双方之间纵向和横向联系的交叉性,人的体育行为的影响及体育教学系统处于走向有序的动态过程中有些隐患尚未暴露等,这时,所得到的最优模式往往处于一种不稳定状态。这说明,体育教学的认识与实践不仅表现在优范畴内的探 Since ancient times, non-excellent thoughts occupy a very important and special position in the history of human cognition, and people always attach great importance to learn from failure.In the practice of physical education, not only the process and result of the pursuit of optimization are aiming, but also to avoid Into non-optimal or failure of the situation. According to the related theory of system engineering, we can abstract the physical education system as a certain model, and get the optimal solution of the whole physical education system under the condition of satisfying the constraints. However, due to the high complexity of PE teaching practice, for example, there are many unknown factors and uncertainties, the intersection of vertical and horizontal linkages between teaching and learning, the influence of PE behavior and the tendency of PE teaching system towards Some hidden dangers in the dynamic process of the sequence have not been exposed, etc. At this moment, the optimal pattern obtained is often in an unstable state. This shows that the understanding and practice of physical education is not only reflected in the excellent category exploration
