数学概念是人类对现实世界空间形式和数量关系的概括反映,是数学知识的基础,是数学思想与方法的载体,是建立数学法则、公式、定理的基础,也是运算、推理、判断和证明的基石,更是数学思维交流的工具。由于数学概念的抽象性,使得教学有一定的难度。教师在教学中,要结合概念的特点和学生的实际,优化概念教学,实现有效的课堂学习。
Mathematical concept is the general reflection of mankind’s relation to the form and quantity of the real world space. It is the basis of mathematical knowledge, the carrier of mathematical thought and method, the foundation of mathematical rules, formulas and theorems, as well as the operation, reasoning, judging and proving Cornerstone, it is a tool for the exchange of mathematical thinking. Due to the abstraction of mathematical concepts, teaching makes it somewhat difficult. Teachers in teaching, we must combine the characteristics of the concept and the students’ actual situation, optimize the concept of teaching, to achieve effective classroom learning.
