概念是客观事物的本质属性在人脑中的反映,是最基本的数学思维形式.在初中数学教学中,数学概念反映了现实世界的空间形式和数量关系,是数学知识的构成基础.数学概念较为抽象,受到初中生智力与思维的影响,必须结合学生心理发展特点展开概念教学.同时,数学概念教学也是学习法则、公式和定理教学的前提,对促进数学知识的实践应用也有显著的作用.本文从概念教学的实践出发,谈谈在概念教学过程中的一些体会.
Concept is the reflection of the essential attribute of objective things in the human brain, which is the most basic form of mathematical thinking.Mathematical concepts reflect the spatial form and quantitative relationship of the real world in junior high school mathematics teaching, and form the basis of mathematical knowledge. More abstract, influenced by the intelligence and thinking of junior high school students, the concept teaching must be combined with the characteristics of the students’ psychological development.Meanwhile, the concept teaching of mathematics is also the premise of learning rules, formulas and theorem teaching, and also plays a significant role in promoting the practical application of mathematical knowledge. Based on the practice of concept teaching, this article talks about some experiences in the process of concept teaching.
