一、忽视数学概念的一些现象概念是反映事物本质属性的思维形式,数学又是研究数量关系和空间形式的科学,数学概念是反映数学对象的本质属性的思维产物,它具有高度的概括性、抽象性、特有性等特点,而所有的数学知识都是由相关的数学概念(定义)衍生出来的,因此,数学概念对于教学来说很重要.由于它的抽象性教师讲解可能很难讲清楚,学生也很难理解概念的本质,因此概念教学往往容易受到忽视.现在,很多刚刚走上教学岗位的中小学 First, neglect of some concepts of mathematical concepts is to reflect the nature of the thinking of things, mathematics is to study the relationship between quantity and space in the form of science, mathematical concepts reflect the nature of the mathematical object of the product of thinking, it has a high degree of generality, Abstraction, uniqueness and so on, and all the mathematical knowledge is derived from related mathematical concepts (definitions), so the concept of mathematics is very important for teaching.Because of its abstract teacher’s explanation may be difficult to clarify , Students are also difficult to understand the nature of the concept, so the concept of teaching is often easily overlooked now, many of the primary and secondary schools have just embarked on teaching
