一、小实验有巩固知识,提高教学效率的作用进行小实验过程中运用的原理都是相应的物理知识,因此进行小实验的过程就是一个很好的复习步骤,可以让初中生更好地理解知识,提高初中生的物理综合水平。课堂作业中也涉及小实验,老师应当深入研究教材和参考书,选择一些简单、有趣又有代表性的小实验让初中生在课堂上去做,多给初中生制造一些动手操作的机会,让学生学会自己设计实验、操作实验,最后解决问题。老师应当要求初中生根据自己的实际情 First, a small experiment to consolidate the knowledge and improve the efficiency of teaching The role of small experiments in the process of applying the principles are the corresponding physical knowledge, so the process of small experiments is a good review of the steps that junior high school students can better understand Knowledge, improve junior high school physics level. Small assignments are also involved in class assignments. Teachers should conduct in-depth study of teaching materials and reference books, select simple, interesting and representative small experiments for junior high school students to do in class, and give junior high school students some hands-on opportunities for students Learn to design experiments, manipulate experiments, and finally solve problems. Teachers should ask junior high school students according to their own actual situation
