物理概念是客观事物的物理本质在人们头脑中的反映,是物理事物的抽象,是物理学知识体系的基本组成要素。物理概念教学是初中物理教学的核心问题之一,它是青少年学生学习物理规律,应用知识解决物理问题的基础,又是培养学生思维能力,接受科学方法熏陶的重要途径。概念教学的优劣,对教学质量与效果有着决定性的影响。本人认为初中物理概念大体可分为两类,一类是定性概念,一类是定量概念,现就不同概念的具体教学方法叙述如下:
The concept of physics is the reflection of the physical essence of objective things in people’s minds, the abstraction of physical things and the basic component of the system of knowledge of physics. Physical concept teaching is one of the core problems in junior high school physics teaching. It is an important way for young students to study the laws of physics, apply knowledge to solve physical problems, cultivate students’ thinking ability and accept scientific methods. The pros and cons of concept teaching have a decisive influence on the quality and effectiveness of teaching. I think junior high school physics concepts can be divided into two categories, one is the qualitative concept, one is the concept of quantitative, different concepts on the specific teaching methods are described below:
