数学学习过程中,错误在所难免,关键在于教师如何看待利用。学生的错题其实暴露出学生在相关知识点中认知的错误和理解思维的障碍。教师要对比联系,扫清概念认知误区;注重习惯,扫清理解题意障碍;细节分析,弥补有意注意缺失;逆向训练,避免思维定势干扰等要素帮助找出问题所在,提升数学教学的效益。 In mathematics learning process, mistakes are inevitable, the key lies in how teachers view the use of. Students ’mistakes actually expose the students’ cognition mistakes in the related knowledge points and obstacles to understanding thinking. Teachers should compare and clear the concept of cognitive errors; pay attention to habits, clear understanding of obstacles; detailed analysis to make up for intentional lack of attention; reverse training, to avoid interference with other factors such as thinking to help identify the problem, improve mathematics teaching benefit.
