数学概念是数学知识的基本构成单位,是数学思维发生和发展的前提,概念教学在数学教学中占据十分重要的地位。随着对概念教学的深入研究,人们已逐渐认识到,概念联系在促进学生概念理解方面发挥着重要作用。说学生对一个概念理解了,就是指学生在头脑中建立了关于这一概念的比较充分的概念联系,从而使这一概念成为了学生已有知识网络的一部分。这个认识对数学概念教学具有重要的指导意义。笔者以为,在小学数学中,“概念联系”主要包括三方
The concept of mathematics is the basic unit of mathematical knowledge, the premise of the occurrence and development of mathematical thinking, and the concept teaching occupies a very important position in mathematics teaching. With the in-depth study of concept teaching, people have come to realize that concept connection plays an important role in promoting students’ conceptual understanding. Saying that a student understands a concept means that the student has established a relatively adequate conceptual connection about that concept in his mind that makes this concept part of the student’s existing knowledge network. This understanding is of great guiding significance to mathematics concept teaching. In my opinion, in primary school mathematics, “conceptual connection” mainly includes three parties
