中学数学教学大纲指出:“正确理解数学概念,是掌握数学基础知识的前提”。这就指明了数学概念与数学其他基础知识的关系,也指明了数学概念在数学教学中的重要地位。下面谈谈我在概念教学中的一些粗浅体会,不当之处,请批评指正。一、要十分重视使学生形成正确的数学概念数学概念是反映数学对象的一般属性与本质属性的一种思维形式,也是形成定理、公式、法则等的出发点。对每个数学概念必须要求学生不仅深刻理解概念的内涵,而且要搞清概念的外延,并学会
The middle school mathematics syllabus pointed out: “The correct understanding of mathematical concepts is the prerequisite for mastering the basic knowledge of mathematics.” This indicates the relationship between mathematical concepts and other basic knowledge of mathematics, and also indicates the importance of mathematical concepts in mathematics teaching. Let’s talk about some of my superficial experience in the concept of teaching, inappropriate, please criticize and correct me. First, we must attach great importance to making students form the correct mathematical concept The mathematical concept is a form of thinking that reflects the general attributes and essential attributes of mathematical objects, and is also the starting point for the formation of theorems, formulas, and rules. For each mathematical concept, students must be required not only to deeply understand the connotation of the concept, but also to understand the extension of the concept and to learn
