自课程改革以来,高中物理课堂实验教学的内容和方式一直都在不断的创新和拓展,出现了许多优秀的实验教学资源。但是,仍然有教师对于实验教学功能的相关理论和实际操作存在一定的局限和不足。为此,笔者就物理实验的“情景性”、“对比性”和“探究性”这三方面的教学功能进行阐述和例证,借此推进物理实验教学的改革,提高实验教学的有效性。 Since the curriculum reform, the contents and methods of high school physics classroom experiment teaching have been constantly innovated and expanded, and many outstanding experimental teaching resources have emerged. However, there are still some limitations and shortcomings for teachers in the theory and practice of experimental teaching. To this end, the author expounds and illustrates the teaching functions of the three aspects of physical experiment “situational ”, “contrast ” and “inquiry ” so as to promote the reform of physics experiment teaching and improve the experiment The effectiveness of teaching.
