思考从问题开始,如果没有问题,思考就成了无源之水,无本之木。数学被誉为思维的体操,自然离不开提出问题。有位教育家曾经说过:“小学教师不谙熟发问的艺术,他的教学是不容易成功的。”然而,在实际的教学及教研活动中我们经常发现:部分教师课堂提问具有较大的随意性,不能很好地把握提问时机,提出的问题不够精准,缺乏提问的艺术和技巧,或者提出的问题价值不高,缺乏对生成性问题的预设,导致课堂“低效 Thinking from the beginning of the question, if there is no problem, thinking has become a passive water, no wood. Mathematics is praised as thinking gymnastics, naturally can not do without asking questions. One educator once said: ”Primary school teachers are not familiar with the art of asking questions, and his teaching is not easy to succeed." However, in actual teaching and research activities, we often find that some teachers have larger questions Can not properly grasp the timing of the question, the question is not precise enough, the art and skill of the question is not enough, or the value of the question is not high, the lack of presupposition of the question of formation causes the class to be inefficient
