本文试以初中物理《声音的发生和传播》一节的教学为例，简单地分析在课堂教学中如何进行实验教学的“编、导。演”。l实验的设计——编所谓编，是指合理地设计一堂课的实验内容。一般原则是重点分析研究教材所精选精编的实验内容，其次，再根据教学需要改进或补充相应的实验。 This article tries to use the teaching of junior high school physics “The Occurrence and Dissemination of Sound” as an example to simply analyze how to carry out the “editing, guiding, and performing” of experimental teaching in classroom teaching. l The design of experiments - the so-called editing, refers to the rational design of the experimental content of a class. The general principle is to focus on the analysis of the experimental content selected by the research textbooks. Secondly, the corresponding experiments should be improved or supplemented according to the teaching needs.
