在中学数学教学中,概念课是基本的课型之一.概念如何引入,以什么方式引入,对学生认识概念、理解概念和运用概念解决问题会起到十分重要的作用.学生获取概念的方式有两种,一种是学生对同类事物中若干个不同例子进行感知、分析、比较和抽象,以归纳概括出这类事物的本质特征属性,从而获得概念的方式;另一种是学生根据已有的知识和经验,从数学知识的联系入手,重在推进式展示概念的方式.借此,笔者就在数学概念课中如何寻找生长点
In middle school mathematics teaching, the concept class is one of the basic course types.How to introduce the concept and how to introduce it will play an important role in understanding the concept, understanding the concept and using the concept to solve the problem. There are two kinds. One is that students perceive, analyze, compare and abstract several different examples of similar things in order to summarize and summarize the essential characteristic attributes of such things so as to obtain the concept of the way. Some knowledge and experience, starting from the connection of mathematical knowledge, focuses on the way of promoting the concept of display, so how can I find the point of growth in the concept course of mathematics?
