“错误”是一个内涵深、外延广的大概念。当我们把错误放到“小学数学课堂教学”这一特定的情境中来审视时,“解错题”就成了它最显性的载体。本文将由一道错误率较高的习题出发,从教师与学生两个维度来分析“解错题”的成因,提出有效的策略引领学生走出错误的困扰。一、问题描述在一次六年级数学检测中,有一道选择题的出错率极高,而这种题型正是教师平时强调过多次的 “Error ” is a big concept of deep, extensive extension of the concept. When we put the mistake into the specific situation of “elementary mathematics classroom teaching”, “wrong title” becomes its most dominant carrier. This article will be based on a higher error rate of the problem, from the two dimensions of teachers and students to analyze the causes of “wrong title”, put forward effective strategies to lead students out of trouble. First, the problem description In a sixth-grade mathematics test, there is a multiple choice error rate is extremely high, and this type of question is the teacher usually stressed too many times
