一、认真做好分组实验认真做好学生分组实验是激发学生学习兴趣的较好手段,是初中物理教学中大面积提高教学质量很重要的一环。但是,在教学过程中,我们发现演示实验和学生分组实验都存在着一定的弊端。课堂中的演示实验是教师为学生提供感性认识材料的过程,它无法代替学生自身的学习 First, conscientiously do a group experiment Seriously do a good job of grouping students is a better way to stimulate students’ interest in learning. It is an important part of improving teaching quality in a large area in junior high school physics teaching. However, during the teaching process, we found that there are some drawbacks in the demonstration experiment and the student group experiment. The demonstration experiment in class is the teacher’s process of providing perceptual knowledge to students, it can not replace the student’s own learning
