物理学中最重要的是物理概念和物理规律,而物理概念是物理规律的基础,因此物理概念的教学具有基础性作用。提高初中物理概念教学的有效性,是学生学好物理学科的关键。提高初中物理概念教学的有效性途径主要有四条:一是巧设物理概念的引入;二是理解物理概念的内涵;三是拓展物理概念的外延;四深化物理概念的应用。
The most important in physics is the concept of physics and the laws of physics, and the concept of physics is the basis of the laws of physics, so the teaching of physics has a fundamental role. Improving the effectiveness of junior middle school physics teaching is the key to learning physics well. There are four main ways to improve the effectiveness of junior high school physics teaching: one is to introduce the concept of physics; the other is to understand the connotation of the concept of physics; the other is to extend the extension of the concept of physics; and the application of four concepts of physics.
