九年义务教育初中物理教材中共编入了29个课后“小实验”,教学中充分重视小实验教学,既有利于巩固知识、提高能力,又容易引起学生的兴趣,对于全面提高教学质量有很重要的作用。第一,加深对所学知识的理解。小实验都是紧扣课文内容的,所以做好课后小实验能把课堂上抽象的概念直 The nine-year compulsory education junior middle school physics textbooks included 29 “small experiments” after class. The teaching of small experimental teaching will not only help to consolidate knowledge and improve abilities, but will also arouse students’ interest. This will improve overall teaching quality. Very important role. First, deepen understanding of what you have learned. The small experiments are closely related to the content of the text, so doing a small experiment after class can straighten the abstract concepts in the class.
