让学生切实掌握好数学概念,从而为以后教学打好基础,这是教学中一个大问题。因为正确理解数学概念,是掌握数学基础知识的前提。概念一般说来比较抽象,但是又很普遍,哪里有思维活动,哪里就会有概念的出现和运用;哪里要用到知识,那里就要有用大大小小的概念来表达。可以说概念是思维的细胞,是表达知识的形式。所以在教学过程中学生牢固掌握概念是十分重要的。有些学生对于题目不能灵活运用,归根结谛还是没有真正掌握好概念。
Allowing students to master the concept of mathematics, so as to lay the foundation for future teaching, this is a big problem in teaching. Because of the correct understanding of mathematical concepts, mathematics is to grasp the basic knowledge of the premise. Concepts in general are more abstract, but very common, where there are thinking activities, there will be the emergence and use of concepts; where to use knowledge, there must be useful to express the concept of large and small. Can be said that the concept of thinking cells, is to express knowledge in the form. Therefore, students in the teaching process firmly grasp the concept is very important. Some students can not be flexible for the use of the title, the ultimate meaning or not really grasp the concept.
