(三)及时分类整理,帮助学 生建立概念系统 任何水平的理解,总是以已有的 知识和经验为基础的。如果已有的知 识是各自孤立的,一方面会妨碍对这 些知识本身的进一步加深理解;另一方面又将影响到利用这些知识间的关系去理解新知识。小学数学教材中的任何一个概念,也都不是孤立存在的。每一个概念和它周围概念之间总是既有一定的联系,又有一定的区别。这种联系与区别,使概念形成系统。如果不在概念系统中去学习概念,就无
(C) timely classification, to help students establish any level of understanding of the conceptual system, always based on existing knowledge and experience. If the existing knowledge is isolated, on the one hand it will hinder further understanding of the knowledge itself; on the other hand, it will affect the use of the relationship between the knowledge to understand the new knowledge. Neither concept in elementary mathematics textbooks exists in isolation. There is always a certain connection between each concept and the concepts around it, with some differences. This connection and difference make the concept form a system. If you do not learn concepts in the conceptual system, there is no
