数学学习离不开数学解题,学生在解题过程中难免会发生错误.美国心理学家桑代克说过:“学习的过程是一种渐进的尝试错误的过程.”钱学森也说过,正确的结果是从大量的错误中得出来的,没有大量的错误作台阶,也就登不上正确结果的高台.如何让学生在错误中成长,让解题错误成为一种宝贵的再生资源,教师首先要读懂学生的错误,再利用纠错的机会去引导学生走出错误的沼泽地.用引申、联想、归纳等手段借题发挥,正确 Mathematical learning is inseparable from mathematics problem solving, students in the process of solving problems will inevitably be wrong.American psychologist Thunder Dick said: “Learning process is a gradual attempt to error process. ” Qian Xuesen also said The correct result is drawn from a large number of mistakes, without a large number of mistakes as a platform, also can not board the correct results of the high platform.How to make students grow in error, so that problem-solving mistakes become a valuable regeneration Resources, teachers must first understand the students’ mistakes, and then use the opportunity of error correction to guide students out of the wrong swamp .Expansion, association, inductive and other means to play the problem, correct
