实验是物理教学的重要手段,实验的特点是真实、直观、形象和生动,易于激起学生的学习兴趣。现从以下几方面谈谈先课外实验后进行教学的课改尝试,供参考。一、课外实验是课堂教学的重要补充,能激发学生学习物理的兴趣。现行初中物理课本中,安排了很多实验,如探 Experiments are an important means of physics teaching. The characteristics of experiments are real, intuitive, vivid and vivid, and they are easy to arouse students’ interest in learning. Now from the following aspects, we will talk about the teaching reform after the first experiment. First, extracurricular experiments are an important supplement to classroom teaching and can stimulate students’ interest in learning physics. In current junior middle school physics textbooks, many experiments have been arranged.
