问题的提出 我们在《对体育运动中开放性运动技能的实验研究(Ⅰ)》中,初步验证了鲍尔顿(1975年)对开放性技能的学习和完成与外界相关变化因素之间关系的假设——开放性运动技能在学习和完成时,环境因素在不断变化,重要的是必须确切地把握这些变化,并在此基础上控制自己的运动以适应这种变化 我们还进一步证实了——鲍尔顿所谓对环境变化的“确切把握”,至少应包含这样两重意义:第一,是指对环境变化因素认知的确切程度——准确性。其二,是指对这些相关变化所能认知的数量——全面性
PROBLEM PROBLEMS We tentatively validate the relationship between the learning and completion of open skills by Ballton (1975) and the factors associated with changes in the outside world in “An Experimental Study of Open Exercise Skills in Physical Education (Ⅰ) Hypothesis - Open Exercise Skills At the time of study and completion, environmental factors are constantly changing, and it is important that these changes be accurately captured and on the basis of which control of one’s own movement is adapted to the change. We further confirm that - The so-called ”exact grasp" of the environmental changes by Powell should include at least the following two meanings. First, it refers to the exact degree of the cognition of environmental change factors - accuracy. Second, it refers to the amount that can be recognized about these related changes - comprehensiveness
