曲线运动一章的教学,需要渗透解决曲线运动的方法——运动的合成与分解。而在运动的合成与分解的教学中需要强调几个特点,即等时性、等效性、独立性。对于前两个特点不用说了,而对于运动的独立性,即认为各分运动相互独立,互不影响。这个观点看似正确,因为平抛运动就是一个很好的例证。但是细细想来该观点还是值得商榷的,何为独立,即无论对于怎样的运动形式,其中的一个分 Curriculum Chapter movement teaching, the need to infiltrate the solution to the curvilinear movement - movement synthesis and decomposition. In the synthesis of sports and decomposition of the teaching need to emphasize several characteristics, namely isochronism, equivalence, independence. Needless to say, for the first two features, independence for the movement means that the sub-movements are independent and do not affect each other. This view seems correct, because the flat throwing movement is a good example. However, it is openly debatable whether this view is meticulously detailed or not. What is independence? No matter what kind of sport form, one of these points
