概念是客观事物的本质属性在人们头脑中的反映,概念教学的过程是认识从感性上升到理性的过程。数学概念是现实生活中某一数量关系和空间形式的本质属性在人的思维中的反映。按概念的抽象水平可以将概念分为描述性概念和定义性概念两类。描述性概念是可以直接通过观察获得的概念,如“长方形”等;定义性概念的本质性特征不能通过直接观察获得,必须通过下定义来揭示,如“偶数”就是通过定义“能被2整除的数叫做偶数”来揭示偶数的本质特征的。不管是哪一类概念,都是小学生掌握数学基本知识和基本技能的基石,都将直接影响以后继续学习及思维能力的发展。
Concept is the reflection of the essential attributes of objective things in people’s minds. The process of conceptual teaching is the process of recognizing the rise from sensibility to rationality. The concept of mathematics is a reflection of the essential attributes of a certain number of relations and spatial forms in the real world in human thinking. The conceptual level of abstraction can be divided into two kinds of concepts and descriptive concepts. Descriptive concepts are concepts that can be directly obtained by observation, such as “Rectangle ”, etc. The essential features of a definitional concept can not be obtained through direct observation, but must be revealed by the following definitions. For example, “even number ” is defined by “The number divisible by 2 is called even number” to reveal the essential features of even numbers. No matter what kind of concept, primary school students master the basic knowledge of mathematics and the cornerstone of basic skills, will have a direct impact on the future to continue learning and development of thinking skills.
