我们知道,影响标枪成绩的主要因素有三个:即投掷枪的初速度、出手角度、空气阻力。在标枪教学时,运用假设法进行教学,不仅能及时地发现错误,预防错误动作的出现,而且能使学生尽快地建立正确的技术概念,能有效地提高教学效果,促进标枪运动的发展。下面笔者根据自己的教学体会,介绍几点方法。一、假设标枪成绩与投出标枪的初速度无关在进行标枪教学时,首先给学生提出标枪成绩与投出枪的初速度无关的问题,有意识地让学生自己通过实践来证明这个问题的正确性。开始让学生手持标枪,做 We know that there are three main factors that affect the performance of javelin: throwing guns at the initial speed, shot angle, air resistance. In the teaching of javelin, the use of hypothetical method of teaching, not only in time to find errors, to prevent the emergence of wrong moves, but also enable students to establish the correct technical concepts as soon as possible, can effectively improve the teaching effectiveness and promote the development of javelin movement. The author below according to their own teaching experience, introduce a few ways. First, assume that the javelin test results and javelin throwing the initial velocity has nothing to do In the teaching of javelin, first of all to the students javelin throwing gun performance and the initial velocity has nothing to do with the issue, consciously let the students themselves through practice to prove the correctness of the issue . Start letting students carry javelins and do
