摘  要:物理实验在物理教学中一直都起着至关重要的作用。近年来物理教学中对物理实验的关注度都不是特别高，并且新课改中似乎有弱化物理实验的趋势，本文就这个现象进行了分析研究，并且归纳整理了物理实验在中学物理教学中的四个功效：创设良好的物理情境、激发学生学习兴趣、培养学生技能和思维方式、引发认知冲突从而转变前概念。旨在通过对物理实验在物理教学中的功效研究，针对我国的课堂教学现状，提高中学教师对物理实验的重视程度。

Abstract:Physics experiment in the physical teaching always plays a vital role. In recent years the attention of physics experiment were not very high In the physical teaching process, and the new curriculum reform seems to have weakened the trend of physics experiment, this paper studied the phenomenon, and the generalization physical experiment in high school physics teaching in four functions: creating good physical situation, stimulates the student to study the interest, and fostering students' skills and thinking mode, cause to change before cognitive conflict concept. Through the research on physics experiment in physics teaching efficacy research, this essay is aiming to improving degree of attention paid to physics experiment according to the present situation of the classroom teaching of middle school teachers.
