排球初学者扣球挥臂动作僵硬产生的原因及纠正方法

The Reason and Rectification of Stiff Smash Actions by Volleyball Learners

教师要抓住学生心理活动的特点，有些学生好胜心强，只看教师扣球的效果，而不注意动作要领，这就要求教师在教学中，培养学生正确地观察能力，教师边示范，边用形象化语言，引导学生重视观查动作，加深学生对动作的理解。同时讲明打球的力量不是靠大臂硬压，而是靠腰、背、手臂、手腕形成象鞭子一样的拍击力，这样学生结合动作联想，在脑子中形成正确的运动力表象，学生就会把注意力放在动作上。

Teachers should master the character of the students' psychology. Some students love to excell others. They don't pay attention to essentials of the actions, but only care for the effects. Teachers are required to cultivate the students' correct observation abilities. Teachers should guide students to value watching actions, and help them to get a deeper understanding. It needs that teachers may use live wolds and demonstration as well. It also should be explained that the strength of smash is not from the upper arm, but from the waist, back, arm and wrist, which form a lash strength. In this way, students may have the right idea in their minds, and they may pay attention to the smash actions.
