本文从弃旧迎新、他山攻玉、兴利除弊、百折不挠等方面指出了演示实验改进的途径。并列举了根据上述途径改进几个演示实验。一、问题的提出物理演示实验能将平时生活中不明显的物理现象演示出来,或者将某些现象所隐含的物理规律挖掘出来,再者能把抽象化形象,因此物理演示实验是解决上述问题的一个有效途径。基于这一点教材上提供了一些基本演示实验,这些演示实验 This article points out the way to demonstrate the experiment improvement from abandoning the old, welcoming others to jade, sweeping the advantages and disadvantages, perseverance and so on. And enumerated according to the above ways to improve several demonstration experiments. First, the issue put forward Physical demonstration experiment can be obvious in everyday life is not obvious physical phenomena, or some of the physical phenomena implied by the excavated rules, and can abstract the image, so the physical demonstration experiment is to solve the above An effective way to solve the problem. Based on this textbook provides some basic demonstration experiments, these demonstration experiments
