1问题的提出我们知道“问题是数学的心脏”,我们还知道爱因斯坦曾指出“提出一个问题比解决一个问题更为重要,因为解决问题也许是一个数学上或实验上的技能而已,而提出新的问题、新的可能性,从新的角度去看旧的问题,却需要创造性的想象力,而且标志着科学的真正进步．”数学学习过程就是不断提出问题、解决问题的过程．问题决定学习的方向、深度,问题提出的质量决定学习的质量,没有问题就
1 Questioning We know that “the problem is the heart of mathematics.” We also know that Einstein pointed out that “proposing a problem is more important than solving a problem, because solving a problem may be a mathematical or experimental skill.” Presenting new problems, new possibilities, and looking at old problems from a new perspective requires creative imagination and marks the true progress of science. The process of mathematics learning is the process of constantly asking and solving problems. The problem determines the direction and depth of study, and the quality of the problem determines the quality of learning. There is no problem.
