学习数学,离不开解题,在解题过程中有正确的认知,也有错误的认知,不可否定“正确”乃解题之本,然而在教学中不仅要注重问题的正确认知的直接效果,还要重视命题系统的错误认知,通过科学有效的错析设计,分析错误的原因,帮助学生摆脱错误的困扰,本文就学生解题失误进行如下归类剖 Learning mathematics is inseparable from solving problems. In the process of solving problems, there are correct cognitions and wrong cognitions. You can’t deny that “correct” is the basis for problem solving. However, in teaching, you should not only pay attention to the positive confirmation of problems. The direct effect of knowledge, we must also pay attention to the mistaken understanding of the proposition system, through scientific and effective error analysis design, analysis of the causes of the error, to help students get rid of the wrong problems, this article on the students to solve the problem of mistakes are classified as follows
