数学核心素养“量感”的认识和培养

Understanding and Cultivating the “Sense of Quantity” of Mathematical Core Literacy

摘要: 人类科学发展的历程中，“量”在各领域皆有着举足轻重的地位，也是数学学习的基础根基。“量感”能力作为数学核心素养的典型代表，它主要是指对事物的可测量属性及大小关系的直观感知能力。量感能力的培养有助于提高学生估测及解决问题的能力，而做到对“量”及“量感”的正确认知是培养学生量感能力乃至提升数学核心素养的必由之路。本文由如何认识“量感”出发，阐述了“量”及“量感”在科学发展中的作用及数学学科中的地位，进而对数学教学中的量感培养进行分析。

Abstract: In the process of human scientific development, quantity plays a crucial role in various fields and is also the foundation of mathematical learning. The ability to sense quantity, as a typical repre-sentative of mathematical core literacy, mainly refers to the intuitive perception ability of meas-urable attributes and size relationships of things. The cultivation of quantitative ability helps to improve students’ ability to estimate and solve problems, and achieving a correct understanding of “quantity” and “quantitative sense” is the only way to cultivate students’ quantitative ability and even enhance their mathematical core literacy. Starting from how to understand “sense of quantity”, this article elaborates on the role of “quantity” and “sense of quantity” in scientific development and the position of “sense of quantity” in mathematics, and then analyzes the cultivation of sense of quantity in mathematics teaching.
