教学实践表明,一些学生解题时,思路呆滞,效率低,影响了对物理基础知识的再认识。下面就几个主要因素进行剖析. 一、摆脱不了教材的模式例1.如图1所示,AB是一个倾角为α的足够长的斜面,一小球从A点以初速度v_0作平抛运动,求小球从抛出开始经多长时间,小球与斜面间的距离最大,最大值是多少? The teaching practice shows that when some students solve problems, their thinking is sluggish and their efficiency is low, which affects the re-understanding of the basic knowledge of physics. The following are some of the major factors to analyze. First, can not get rid of the model of teaching materials Example 1. As shown in Figure 1, AB is a slope long enough slope α, a small ball from the A point to the initial speed v_0 flat throw Exercise, how long does it take for the ball to start throwing, and what is the maximum distance between the ball and the slope?
