在当前减负提质的背景下,教师们都在为如何提高课堂效率八仙过海,各显神通。在数学课堂中学生不可避免产生错误,许多错误被教师捕捉到、处理方法得当就会成就精彩课堂,个性化的错误被纠正过来会提高学习准备效率。本文从课堂数学错误的预设性与非预设性进行分类、应对入手,谈谈平时笔者的一些积累,旨在提高学生的学习效率,做到减负不减质。
In the context of the current burden of upgrading, teachers are how to improve classroom efficiency. In mathematics classroom students inevitably produce errors, many mistakes are caught by teachers, the right approach will lead to wonderful classroom, personalized mistakes will be corrected to improve the efficiency of learning preparation. This article classifies the presuppositions and non-presuppositions of mathematical mistakes in the classroom, and starts with what we usually accumulate in order to improve students’ learning efficiency and reduce burdens and losses.
