任何事物都是由系统构成的,而系统都是有结构、分层次的。小学数学教材也是一个整体,各册、各单元之间联系紧密,要引导学生对概念间作纵向、横向联合的归类、整理,找出概念间的内在联系,将平常所学孤立的、分散的知识串成线,连成片,结成网。这样有助于学生从整体上理解和掌握概念间的内在联系,以便记忆和运用。同时应结合一定量的针对性练习,凭借一定次数考试及试卷的讲评,来诊断、调节、提升学生的学习,促进学生有效发展。 Everything is made up of systems, and systems are structured and hierarchical. Primary mathematics textbook is also a whole, each book, all the units are closely linked, to guide students to conceptualize vertical and horizontal joint classification, sorting, find out the internal relations between concepts, will usually learn isolated, decentralized Knowledge string into a line, even into a film, forming a network. This will help students to understand and grasp the internal relations between concepts as a whole for memory and application. At the same time, a certain amount of targeted exercises should be combined with a certain number of examinations and examination papers to diagnose, adjust, enhance students’ learning and promote the effective development of students.
