一、引言物理概念是用来表征物质的属性和表述物质运动状态的,任何物理概念都是从物理现象、物理事实中抽象出来的.物理概念既是构建物理知识的基元,又是物理思维的基础,还是培养学生创新能力的基石.教学实践表明,学生在物理学习上出现的问题大多来源于物理概念不清,由于对概念理解不透、混淆不清,就很难了解各公式、各定律的内在联系和深刻含义,对所学物理知识必然难以收到“举一反三、触类旁通、融会贯通”的成效.所以,对概念理解得如何从根本上说决定了学生学习的效果.况且,每年的物理高考试题中必有一定量的概念题,而且着重考查的就是学生对物理概念的确切含义是否理解,能否鉴别关于概念的似是而非的说法,能否认识相关概念的区别和联系等.因此,物理概念的教学显得极为重要,教师教好物理概念乃是学生学好物理的关键 I. INTRODUCTION The concept of physics is used to characterize the properties of matter and to express the state of motion of matter. Any physical concept is abstracted from physical phenomena and physical facts. The concept of physics is not only the basis for constructing physics knowledge, but also physical thinking. The foundation is also the cornerstone of cultivating students’ innovative ability. Teaching practice shows that most students’ problems in physics learning come from unclear physics concepts. It is difficult to understand formulas and laws because the concepts are not clearly understood and confused. The intrinsic connection and profound meaning of the physics knowledge learned will inevitably make it difficult to receive the results of “inferring from the fact that it is by analogy, by analogy, and integration.” Therefore, how the understanding of concepts fundamentally determines the effectiveness of student learning. Moreover, each year There must be a certain amount of concept questions in the physics examination questions, and the examination focuses on whether the students understand the exact meaning of the physics concepts, whether they can identify plausible arguments about the concepts, whether they can recognize the differences and relations between related concepts, etc. Therefore, physics The teaching of concepts is extremely important. Teachers’ teaching of physical concepts is the key to students’ learning of physics.
