凡思维都是由问题所引起的。学习就是复杂的思维活动,是在教师引导下不断地提出问题、分析问题和解决问题的过程。当代美国著名数学家哈尔墨斯(P.R．Halmos)说,“问题是数学的心脏”,这个比喻是非常恰当的。数学教学基本上就是通过问题进行的。可以说,在数学教学中,小学生逻辑思维能力只有通过问题教学才能培养和发展。因此,训练小学儿童的逻辑思维,就要有意识、有目的地选择问题,精选习题,启发、引导他们积极思考,通 Every thought is caused by the problem. Learning is a complex thinking activity, which is the process of constantly asking questions, analyzing questions and solving problems under the guidance of teachers. The famous American contemporary mathematician P.R.Halmos said that “the problem is the heart of mathematics.” This metaphor is quite appropriate. Math teaching is basically done through questions. It can be said that in mathematics teaching, pupils' logical thinking ability can be cultivated and developed only through question teaching. Therefore, to train primary school children's logical thinking, we should consciously and purposefully choose problems, select exercises, inspire them and guide them to think actively and pass
