创新中学物理演示实验的几点探索

摘要

The physics demonstration experiment plays the most important role in a class. Owing to this, Started with the angle of experimental device, combined with the teaching experience, all the possibilities of demonstration experiment ineffectiveness or failures were analyzed. Then the writer＇s own practice and experience is discussed about how to improve high school physics demonstration experiment from the following 4 respects： experiment power source, experimental object, experiment display device, equipment for us to adjust and to control experimental conditions .%物理演示实验的成功有效与否，直接关系到一节课的教学效果．鉴于此，从实验装置结构方面着手，结合自己的教学实践，分析了导致演示实验效果不好或失败的可能性，并从实验动力源、实验对象、实验显示器、用以调控实验条件的器材四个方面，对如何改进中学物理演示实验谈了自己的一些体会和做法．
