在取得正确结果的基础上,对解题过程作全面的回顾,并根据问题的特点作深入一步的讨论,不仅有助于认识同类型问题的一般规律,有时还可以从中悟出一些很有用的新的结果。这样,就使解题的收获扩大了。在教学过程中,我们要逐步指导和训练学生做好解题后的这一极有意义的工作,通常可以从这样几方面着手: 一、研究解法,比较特点许多物理问题往往不是只有一种解法,近年来对“一题多解”已引起许多人的兴趣。这里必须注意的是:“一题多解”的目的,并不在于“多”,而在于通过对各种不同解法的研究、比较,可以从不同的角度或用不同的物理规律去思考和解决问题,从而真正达到开拓思维,加深对物理规律认识的目
On the basis of obtaining the correct results, a comprehensive review of the problem-solving process and further discussions according to the characteristics of the issue will not only help us to understand the general laws of the same type of problems but also sometimes help to find out some very useful New result In this way, the problem solving gain expanded. In the process of teaching, we should gradually guide and train students to do a very meaningful work after the problem-solving, usually from these aspects: First, the research solution, more features Many physical problems are often not the only solution In recent years, “one problem and many solutions” has aroused the interest of many people. What must be noted here is that the purpose of “one problem and multiple solutions” does not lie in “multiple” but rather that it can be considered and solved from different perspectives or different physical laws through the research and comparison of different solutions Problems, so as to really develop pioneering thinking and deepen the understanding of the laws of the physical goals
