著名教育家陶行知先生曾经说过:“发明千千万,起点是一问”.爱因斯坦也曾说:“提出一个问题往往比解决一个问题更重要.”纵观科学发展史,几乎每一次质的飞跃都从问题开始,可见问题是科学创新的起源.物理新课程标准也要求学生:“能在观察物理现象或物理学习过程中发现问题,有初步的提出问题的能力.” Mr. Tao Xingzhi, a famous educator once said: “The invention of tens of millions, starting from a question.” Einstein once said: “Proposing a question is often more important than solving a problem.” The history of the development, almost every qualitative leap from the beginning, we can see that the problem is the origin of scientific innovation.New physics standards also require students to: “can be found in the observation of physical phenomena or physical learning process, there are preliminary questions Ability.”
