著名教育家陶行知先生曾经说过:“发明千千万,起点是一问。”纵观科学发展史,几乎每一次质的飞跃都从疑问开始,可见问题是科学创新的源泉。同样,在高中课堂教学中也离不开有效的设问。 Mr. Tao Xingzhi, a famous educator, once said: “The invention of tens of millions starts with a question.” Throughout the history of scientific development, almost every qualitative leap starts from doubt, showing that the problem is the source of scientific innovation. Similarly, in high school classroom teaching also can not do without effective question and answer.
