一、怎样才算把物理概念教好? 学生是否真正掌握(理解)了物理概念。具体标准主要是: 第一:要明确为什么要引入这一概念,它的作用是什么?是怎样定义的? 第二:懂得概念是如何建立起来的?它反映物体的什么本质属性,其物理意义是什么? 第三:明确概念的量值是怎样的(包括是否矢、标量和量纲式)? 第四:能够运用概念去分析、判断和解决新的现象和问题。第五:通过概念的学习,能逐步体会到研究物理问题的方法,并对物理课程的学习越学越顺利,越学越有兴趣。上述各点不可能一气呵成,有它的阶段性与长期性,我在教学中的体会是分三步完成较好,前三条必须在引入概念时完成,这一步很重要,涉及到物理实验、教师的语言和课堂讲
First, what is the teaching of physical concepts? Students really master (understand) the concept of physics. The specific criteria are: First, to clarify why this concept should be introduced, what is its role and how is it defined? Secondly, how do we understand how the concept is established? It reflects the essential nature of the object and its physical significance. What is it? Third: What is the value of a definite concept (including vector, scalar, and dimension)? Fourth: The concept can be used to analyze, judge, and solve new phenomena and problems. Fifth: Through the study of concepts, we can gradually realize the methods of studying physics problems and learn more about physics courses. The more we learn, the more we become interested. The above points cannot be achieved at one go, with its periodicity and long-term nature. My experience in teaching is accomplished in three steps. The first three must be completed when concepts are introduced. This step is very important and involves physics experiments and teachers. Language and classroom
