教好初中物理的重要一个方面,是充分发挥物理实验的作用.实验能够创设情景,激发学习兴趣,还可以把抽象的知识具体化,把本质的东西表象化.如:要体现比较抽象的力的相互作用情景,可以通过实验来完成.学习弹力及弹性形变时,可以用孩子常玩的“丫”型弹弓进行演示,要求学生用所学的知识解释这种弹射的现象,学生亲自体会到物体发生弹性形变所产生的势能.身边发生的很多事情其实都是物理现象,通过实验的演示和引导,学生不但兴趣
Teaching an important aspect of junior middle school physics is to give full play to the role of physical experiments. Experiments can create scenarios to stimulate interest in learning. They can also embody abstract knowledge and visualize essential things such as: Of the interaction scenarios can be completed through experiments.Earning elastic and elastic deformation, you can use the children often play “Ya ” type slingshot demonstration, requiring students to use the knowledge to explain this ejection phenomenon, the students personally Experience the potential energy generated by the elastic deformation of objects.Many things happened around are actually physical phenomena, through the demonstration and guidance of experiments, students are not only interested
