比较是在分析和综合的基础上确定这一事物与另一事物的相同点和不同点的方法,是人们在日常生活中常用的一种思维方式,在面对两种既存在区别又有着联系的事物时,人类的大脑中不由自主的会形成比较,也正是如此,在人们的学习过程中,很多知识的内在区别与联系是在不断的比较中得到的。在儿童的思维过程中,对事物的比较不是有序的、适时的、有效的。因而,在数学教学过程中,运用知识的基本原理和其衔接点进行比较,让学生在比较中思考、分析、使学生易于理解新知识,也易于区别旧知识,更能启发学生的思维,培养学生的探索精神。本文就笔者对比较在数学课堂中的适时运用谈谈几点做法和体会。
Comparison is based on the analysis and synthesis of this thing and determine the same point and different things, is a common way of thinking in daily life, in the face of both the existing and the difference between the two have contact It is also true that human beings can not help themselves in their brains. In the course of people’s learning, the inherent differences and connections of many kinds of knowledge are obtained through constant comparison. In children’s thinking process, the comparison of things is not orderly, timely and effective. Therefore, in the process of mathematics teaching, the basic principle of knowledge is compared with its convergence point, so that students can think and analyze in comparison so that students can easily understand new knowledge, and it is also easy to distinguish old knowledge and inspire students’ thinking and training Student’s exploration spirit. This article on the author of the comparison in the mathematics classroom in a timely manner to talk about how and experience.
