著名教育家陶行知先生曾经说过:“发明千千万,起点是一问”.这句话很好地回答了为什么要在新课程教学中提倡问题情景的创设,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.所以数学新课程标准大力提倡探究性学 The famous educator, Mr. Tao Xingzhi, once said: “The invention of tens of millions, the starting point is a question.” This sentence is a good answer to why we advocate the creation of problem scenarios in the new curriculum teaching and the development of science. History, almost every qualitative leap starts from the problem. It can be seen that the problem is the origin of scientific innovation. Therefore, the new mathematics curriculum standard strongly advocates inquiry learning.
