一、专题概述物理概念是构成物理知识的重要组成部分,学生正确理解、掌握物理概念是学好物理的前提和基础。在学生对基本概念的理解和应用的过程中,只有让学生弄清物理概念的来龙去脉,才能使学生主动深入地了解所要研究的问题,才能使学生自主建构物理概念的内涵与外延,领悟物理研究的科学思维和科学方法。因此选择合适的引入物理概念的方法是至关重要的。在初中物理学中引入概念的方法有很多种,其中用比值法定义物理量是最常见、最 First, thematic overview Physical concepts constitute an important part of physical knowledge, students correctly understand and master the concept of physics is to learn the prerequisite and foundation of physics. In the process of students’ comprehension and application of basic concepts, only by letting students understand the ins and outs of physical concepts can students take the initiative to deepen their understanding of the problems to be studied so as to enable students to construct the connotation and denotation of physical concepts autonomously, Scientific thinking and scientific method. So choosing the right approach to introducing physical concepts is crucial. There are many ways to introduce concepts in junior physics, among which the definition of physical quantities is the most common
