我们在解数学题时,面对一些题目经常会出现:感到无从入手而当老师或同学一点拨,又觉得如此简单,可自己为何就没想到?出现方法不当而造成解题烦琐,甚至出现“会而不对”、“对而不全”等现象。其主要原因是缺乏与解题信息相关的众多数学能力和意识。因此,如何解决入手难以及减少出现这种烦琐的解题过程,培养学生的敏感意识,是数学解题教学中一个十分重要的问题。 When we are solving math problems, we often face some problems when we face the problem: when we feel that we can not start our work and when the teacher or classmates call for something, we think that we can not think of ourselves. Inappropriate ways of solving the problems lead to cumbersome problems, “Will not right”, “right but not” and so on. The main reason is the lack of mathematical knowledge and problem-solving related to the many mathematical skills and awareness. Therefore, it is a very important issue in the teaching of mathematics to solve the problem of how to solve the difficulty and reduce the complicated process of solving problems.
