鲁迅先生说过:“其实地上本没有路,走的人多了,也便成了路。”路是人走出来的,自然界的规律是人在探索的过程中发现的.以应用物理规律解决实际问题的过程中,学生应独立完成,不应有“走的人多了”的情形.学生作为一个探索者,可用尝试的方法,走走看,于无路处辟蹊径,往往会云开雾散,柳暗花明.既能享受到探索的乐趣,又能体会到成功的快感,何乐而不为! Mr. Lu Xun said: “Actually, there is no road on the ground, and there are many people walking. It is also the way.” The road is the way people come out. The laws of the natural world are discovered during the process of exploration. They are solved by the laws of applied physics. In the process of actual problems, students should complete independently and there should be no “more people to go.” Students, as explorers, can use trials and walks to see if there is no way to make a path, and often they will open up. The fog is scattered and the flowers are bright. You can enjoy the pleasure of exploration, and you can experience the thrill of success. Why not!
