“千言万语说不清,一看实验就分明.”高中物理教学离不开实验,演示实验具有耗时少,现象生动、形象等优点,在物理概念建立、规律导出的过程中的作用越发凸显.成功完成演示实验是物理教师教学智慧和艺术展示的集中体现.我在实践中发现,选择好的演示实验并将实验演好,能够有效激发学生的物理学习兴趣,帮助学生深化对概念和规律理解,并促进学生形成正确的观察、思维习惯.本文就如何选好、演好实验进行简单的分析.1紧扣教材,导入新课
“A thousand words can not tell, a clear experiment. ” High school physics teaching can not be separated from the experiment, demonstrating experiments with less time-consuming, vivid images, image, etc., in the physical concept of the establishment of the process of law derived The effect is more and more prominent.Successful demonstration experiment is the concentrated expression of the physics teacher’s teaching wisdom and art exhibition.I found that in practice, choose a good demonstration experiment and the experiment performed well, can effectively stimulate students’ interest in physics learning, to help students deepen the Concepts and rules to understand, and promote students to form the correct observation, thinking habits.This paper on how to choose a good performance of the experiment for a simple analysis .1 closely linked to the teaching materials, into the new class
