文[1]通过学生对一道高考题解答中的错误展开分析和探究,展示了一个经典的纠错教学案例,笔者读罢,有强烈的共鸣之感.“暴露错误的发生过程,剖析错误的产生原因,探讨错误的纠正方法,追求‘不失误’的学习日标.”道出了纠错教学设计的本质规律,不仅有利于提高教学的有效性,也有利于增强学生的数学素养.而在纠错中,让错误暴露得更本质一些,则能更好地揭示问题的数学本质,更有利于提高教师的专业素质.笔者在教学实践中正巧也碰到了文[1]末给出的压轴问题,因此对这道题有一定的认识,有感文 Text [1] through the students on a college entrance examination questions in the analysis and analysis of errors, showing a classic case of error correction teaching, I read the strike, there is a strong sense of resonance. “The process of exposing errors, parsing errors The causes of errors, to find ways to correct the mistakes, the pursuit of ’no mistakes’ of the learning standard. ”The error correction teaching out of the nature of the law not only help to improve the effectiveness of teaching, but also help to enhance students’ mathematical literacy In the error correction, making mistakes more exposed to some of the nature, can better reveal the mathematical nature of the problem, but also help to improve the professional quality of teachers in the teaching practice coincides with the text also hit the end of [1] Out of the finale issue, so there is a certain understanding of this issue, there is a sense of the text
