传统的数学复习教学中,教师往往加大难度而十分注重规范的演绎、推理思维的训练,“操作”与“猜想”被视为一种雕虫小技而打入冷宫。其实初中数学中的许多概念、性质与定理,对于极大部分思维还没有真正理性化的初中生来说,难度是可想而知的。学生在自己解决问题时往往受到阻碍,解决不了困难,就会说代数太 In traditional teaching of mathematics review, teachers tend to increase the difficulty and attach great importance to the standard deduction, the training of reasoning thinking, “operation ” and “guess ” is regarded as a kind of carving skills into cold limbs. In fact, many of the concepts, properties and theorems in junior middle school mathematics can hardly be imagined for junior high school students who have not really rationalized a great part of their thinking. Students are often hampered in their own problem-solving, can not solve the problem, it will say algebra too
