知识是依靠数学思维和数学思想方法联系起来的,每一种数学知识都对应着一个核心内容,把握数学知识的核心,是课堂教学体现数学本质的基本要求。张奠宙教授指出:数学教育,自然是以“数学”内容为核心。以数学内容为核心最基本的应是对数学概念的理解,追求学生能够感受知识产生的必要性,理解所学知识的核心内容,体会知识之间的内在联系。本文以深沪中心小学黄老师执教的“一米有多长”为例,就教学实践中如何找准数学本质,落实知识间
Knowledge relies on mathematical thinking and mathematical thinking methods. Each kind of mathematical knowledge corresponds to a core content. Grasping the core of mathematical knowledge is the basic requirement that classroom teaching embodies the nature of mathematics. Professor Zhang Dianzhou pointed out that mathematics education naturally takes the content of mathematics as the core. To mathematics content as the core of the most basic should be the understanding of mathematical concepts, the pursuit of students to feel the necessity of knowledge generation, understanding of the core content of knowledge, knowledge of the intrinsic link between. In this paper, Shenzhen and Shanghai Central Primary School teacher taught by the “one meter how long ” as an example, how to find out the mathematical nature of teaching practice, the implementation of knowledge
