《数学课程标准(2011年版)》与《数学课程标准(实验稿)》相比有许多变化,其中变化之一是由“双基”变为“四基”。“四基”在原来数学基础知识、基本技能的基础上增加了基本思想、基本活动经验。数学思想是指对数学及其对象、数学概念和数学结构以及数学方法的本质性认识。它蕴涵在数学知识形成、发展和应用的过程中,是数学知识和方法在更高层次上的抽象与概括。目前的小学数学教材数学思想丰富,表现形式也多种多样,如抽象、
There are many changes in the Standard for Mathematical Curriculum (2011 Edition) compared with the Standard for Mathematical Curriculum (Experimental Version), with one of the changes being from “double base” to “quadruple”. “Four Basics ” Based on the original basic knowledge of mathematics and basic skills, we have added basic thought and basic activity experience. Mathematical thinking refers to the essential understanding of mathematics and its objects, mathematical concepts and mathematical structures, and mathematical methods. It is implicated in the process of the formation, development and application of mathematical knowledge, which is the abstraction and generalization of mathematical knowledge and method at a higher level. The current mathematics teaching of primary school mathematics is rich in ideas and forms are also varied, such as abstract,
