概念是思维的基本单位,是认识的起点,正如麦克基尼所言:“如果没有概念,这个世界将会陷入极度的混乱,交流会变得非常困难,概念会帮助我们组织好对世界的认识以及与他人有效的交流.”然而在教学实践中,很多教师并没有充分意识到概念教学的重要性.对概念的教学主要是从自身的经验出发,缺乏概念教学的有效方法,甚至把概念教学等同于定义教学,认为只要记住概念的定义就是掌握了概念,更谈不上发展学生的思维能力.作为一名数学教师,怎样在自己的概念教学 The concept is the basic unit of thinking and the starting point for understanding. As McKinney said: “Without this concept, the world will fall into extreme chaos and communication will become very difficult. The concept will help us organize our understanding of the world And effective communication with others. ”However, in the teaching practice, many teachers are not fully aware of the importance of the concept of teaching.Concept teaching mainly from its own experience, the lack of an effective method of concept teaching, and even the concept Teaching equates to the definition of teaching, that as long as remember the concept of definition is to grasp the concept, let alone the development of students’ thinking ability as a math teacher, how to teach in their own concepts
