一、如何利用举反例提升学生对数学知识点的理解在初中数学学习中,教师虽然会教给学生很多知识点,但是学生并不能完全理解,这是就需要教师以举反例的方式来引导学生加深对知识点的理解,本文笔者将列举几个教学实例,探究如何利用举反例提升学生对数学知识点的理解。实例1:当数学教师在进行图形的教学时,经常会遇到判断两个图形是否全等、求图形面积、求图形一边长度等问题。在遇到“已知三角形ABC与三角形
First, how to use examples to enhance students’ understanding of mathematical knowledge points In junior high school mathematics learning, although the teacher will teach students a lot of knowledge points, but students can not fully understand, this is the way teachers need to counterexample to guide students Deepen the understanding of knowledge points, the author will list a few teaching examples to explore how to use examples to enhance students’ understanding of mathematical knowledge points. Example 1: When the mathematics teacher in the teaching of graphics, often encountered to determine whether the equality of the two graphics, graphics area, the length of graphics and other issues. Upon encountering ”known triangle ABC with triangle
