摘要：物理这门学科是基于实验的一门学科，可以说，物理是离不开实验的。演示实验是物理实验中的一个类型，是物理教学的重要手段和方法。通过演示实验可以让学生更好的接受物理知识，重新体验一下发现的过程，同时为学生形成抽象的物理概念、理解物理规律提供了大量丰富的感性知识，为学生的思维发展提供了广阔的空间。演示实验是整个物理教学极其重要的组成部分，有极其重要的作用。本文主要论述了演示实验在物理教学中重要意义以及对学生能力培养的作用。结合当前物理教学过程中的所出现的问题，分析并提出一些建议，从而使演示实验充分发挥其在物理教学中的作用。

Abstract:It is based on the experiment of a subject for physical this subject . So we can say that physics is cannot leave the experiment. The demonstration experiment an important means of physical teaching and method is a type of physics experiment . Through the demonstration experiment can allow students to accept physical knowledge better, to experience the discovery process, at the same time for students form the abstract concept, understand the physical laws of physics provides a lot of perceptual knowledge, for students' thinking development to provide a broad space. The demonstration experiment is the whole physics teaching of the most important components, has the extremely vital role. In this paper mainly discusses the experimental demonstration in physical teaching important significance as well as the role of students' skills. In the process of teaching, combining the current physical problems occurred in the physical, analysis and puts forward some Suggestions, so that the demonstration experiment give full play to its role in the physical.
Key words: demonstration experiment； physics teaching； teaching problem ；important role
