数学概念是反映数量关系与空间形式本质属性的思维方式,是数学思维的细胞.无论是数学方法,还是解决数学问题,都必须运用数学概念,可以说,数学概念是数学知识的基石.正确而深刻地理解数学概念,是掌握数学基础知识和形成基本技能的前提.夸美纽斯在《大教学论》中指出:“如果先不教明概念,便是教得不好的”.匡继昌在文[1]中指出:“学生如果不能正确地理解数学中的各种概念,就不能掌握各种法则、定理、公式,从而也就不能正确地进行计算和论证.因此,讲清概念,使学生正确地理解概念,对于提高数学教学
Mathematical concept is a way of thinking that reflects the relationship between quantity and the nature of space form, and is the cell of mathematical thinking.Mathematical concepts must be applied to both mathematical methods and mathematical problems, so that mathematical concepts are the cornerstone of mathematical knowledge. A deep understanding of mathematical concepts is a prerequisite for grasping the basics of mathematics and for forming basic skills.Comeini pointed out in his Teaching Theory that ”if you do not teach concepts first, you are not good at teaching them.“ Kuang Ji-chang pointed out in his article [1]: ”If students can not correctly understand the various concepts in mathematics, they can not grasp all kinds of laws, theorems, and formulas, so that they can not correctly calculate and prove them. Concept, so that students correctly understand the concept of mathematics for improving teaching
