中等数学问题的解题过程,一般可分为三个阶段,一、解题前期——审题,分清已知和求解,有时还要画出必要的图形;二、解题中期——解题,选择解法,写出过程,提出初步答案;三、解题后期——检验,鉴别答案是否正确和完整。本文主要分析解题过程中出现的一些思维受阻情况,并提出一些具体克服办法。一、解题前期——审题要思之再思数学题目一定包括了已知条件和解决的问题两个组成部分,解题首先要认真审题,弄清已知和求解,但审题也不是一件易事,必须思之再思,所存在的思维受阻主要表现在:
The problem-solving process of medium-sized mathematics problems can generally be divided into three stages. First, the early stage of problem-solving--question-out, distinguishing known and solved problems, and sometimes drawing the necessary graphs; second, problem solving mid-term-solving problems, Select the solution, write out the process, and present preliminary answers. Third, solve the problem later - test, identify whether the answer is correct and complete. This article mainly analyzes some of the obstacles in the process of solving problems, and proposes some specific ways to overcome them. First, the problem-solving pre-questioning - review questions to think about the re-think mathematics topic must include the known conditions and solve the problem of two components, the problem must first carefully examine the problem, understand the known and solve, but the trial is not a Easily, we must think about it again, and the existence of obstacles in thinking is mainly reflected in:
