物理教学的主要任务是使学生认识物理现象，掌握物理概念和物理现象，掌握物理概念和物理规律，并应用这些概念和规律解决实际问题。在实行新课程改革，更新教学理念的今天，如何进行好概念和规律的教学是物理教学研究的主要课题。我在教学中注意了以下几个方面： 一、做好演示实验，使学生获得形成概念的感性认识 演示实验可使教学直观化、形象化，为掌握概念奠定感性基础。然而，学生观察得到的关于事物的感性认识，往往是表面的、片面的，要使感性认识上升到理性认识，还有一个分析、推理的过程。因此，演示实验不只是单纯为了讲清概念、传授知识，还应注意培养学生的思维能力。在演示过程中要不断提出带有 The main task of physics teaching is to enable students to understand physical phenomena, master physical concepts and physical phenomena, master physical concepts and physical laws, and apply these concepts and laws to solve practical problems. Today, with the implementation of new curriculum reforms and the renewal of teaching concepts, how to carry out the teaching of concepts and laws is the main subject of physics teaching research. In the teaching, I paid attention to the following aspects: First, do a good demonstration experiment, so that students obtain a perceptual understanding of the formation of concepts Demonstration experiment can make teaching visualization, visualization, and lay a sensible foundation for mastering concepts. However, the perceptual knowledge of things observed by students is often superficial and one-sided. It is necessary to raise the perceptual knowledge to rational knowledge, and there is also a process of analysis and reasoning. Therefore, the demonstration experiment is not just to clarify concepts and impart knowledge, but also to cultivate students’ thinking ability. During the presentation, it is necessary to constantly bring
