任何一种创造发明和重大发现都是青出于蓝而胜于蓝,出于蓝就是借鉴前人的经验和知识。没有蓝,青就变成无源之水,胜于蓝就是较前高也一筹。因此就要求不能受原条条框框的束缚,而要做到这一点,第一就要大胆遐想,善于提出问题。物理学中也是如此,如果我们在教学中要求循规蹈距,书上写什么,教师讲什么就学什么,记什么,不敢越雷池一步。那么即使全优,将来也不会有什么作为,充其量他只能出色地重复别人的过去。因此我们教师在教学过程中就要凭借自己一桶水对一杯水的知识优势,鼓励学生浮想联翩,能发现问题。为此教师要做到:勤鼓励,不管提问题学生程度的高低,也不管所提问题的正确与否一律热情鼓励。对于不切实际,漫无边际,瞎想出来的问题,对于钻牛角尖的问题要耐心疏导。将他们的思维逐步纳入正确轨道。对那些学生有能力解决的问题应 Any kind of inventions and major discoveries are blue and blue rather than blue. Out of blue is to learn from their predecessors’ experience and knowledge. Without blue, blue becomes passive water, which is better than blue. Therefore, the request cannot be bound by the constraints of the original rule. To achieve this, the first thing is to think boldly and be good at asking questions. The same is true in physics. If we require discipline in teaching, what is written in the book, what the teacher says, what to learn, and what to remember, dare not go further. Even if they are all excellent, they will not do anything in the future. At best, he can only brilliantly repeat the past. Therefore, our teachers must rely on their own knowledge of a bucket of water for a glass of water in the teaching process to encourage students to think about it and find problems. To this end, the teacher must do the following: Diligence encouragement, regardless of the level of students who ask questions, and whether the questions raised are correct or not. For unrealistic, rambling, imaginary problems, be patient with issues that require patience. Gradually put their thinking on the right track. For those students who have the ability to solve problems
