一、把复杂问题简单化,抽象问题具体化教育家叶圣陶说过:“谁能把把复杂问题简单化,谁就是教育家。”在教学中,我们常常遇到一些复杂的数学问题学生找不到突破口,根据学生的年龄特点和认知水平感觉很难,这就需要我们教师想办法从简单的问题入手,搭建解决问题的支架,使问题化繁为简,从而达到解决问题,突破难点的目的。如八年级上册的三角形全等的“边边边”公理的教学,学生不明白证明两 I. Simplifying Complex Problems and Specifying Abstract Problems Ye Shengtao, an educator, said: “Who can simplify complicated problems and who are educators.” In teaching, we often encounter students with complicated math problems Can not find a breakthrough, according to the characteristics of age and cognitive level of the students feel very difficult, which requires our teachers to find ways to start from a simple problem, to build a solution to the problem of support, so that the problem of simplification, so as to solve the problem, breakthrough The purpose of the difficulty. As in the eighth grade of the triangle congruent “side edge ” axiom teaching, students do not understand the proof of two
