物理是一门以实验为基础的学科。初中物理中的演示实验教学能使教师的“教”和学生的“学”都鲜活起来。下面笔者就演示实验在初中物理教学中的作用谈一些看法。一、利用演示实验设疑,创设情景导入新课好奇心是兴趣的先导,当有悖常理的奇特实验现象展示在学生面前时,便会诱发学生的好奇心,引起学生的思考,从而产生强烈的求知欲。因此,教师可以 Physics is an experiment-based discipline. Demonstration experiment teaching in junior high school physics can make teachers’“teaching” and students’“learning”live. In the following, the author will talk about the role of demonstration experiment in junior high school physics teaching. First, use the demonstration experiment to establish suspicion, create a new scene into the class Curiosity is the forerunner of interest, when the strange and strange phenomenon of the experiment is displayed in front of the students, it will induce students’ curiosity, arouse students’ thinking, resulting in strong Curiosity. Therefore, teachers can
