概念是学生开始学习一个新知识的起步,因此概念教学是中学数学教学中至关重要的一个环节,它是“双基”教学的核心。数学概念的教学一般都要经历概念的形成、概念的表述、概念的辨析、概念的应用(包括概念所涉及的数学思想方法的运用)等阶段。一、应重视概念的产生过程有的教师不讲概念产生的背景,也不经历概念的概括过程,用例题教学替代概念的概括过程,认为“应用概念的过程就是理解概念的过程”。殊不知没有“过程”的教学,因为缺乏数学思想方法为纽带,
Concept is the starting point for students to start learning a new knowledge. Therefore, concept teaching is a crucial link in the teaching of mathematics in middle school. It is the core of “double base” teaching. The teaching of mathematical concepts generally have to go through the formation of concepts, the expression of concepts, the analysis of concepts, the application of concepts (including the application of concepts and methods involved in mathematics). First, the concept should pay attention to the process of generation Some teachers do not talk about the background of the concept of production, nor the concept of the process of generalization, the use of case teaching alternative concept of the general process, that “the process of application of the concept is to understand the concept of process.” Did not know no “process ” teaching, because of the lack of mathematical thinking and methods as a link,
