国外数感研究评析及启示

Analysis and Enlightenment of Number Sense Research in Foreign Countries

数感是国外数学教育的重要内容,也是我国《义务教育数学课程标准(2011年版)》中提出的十个核心概念之一。数感是一个多维度概念,在信息加工理论视角下,数感是一种对数量非精确、快速的知觉过程。在整合国外数感结构模型的基础上,构建数感四面体结构模型。未来需要注重数感的本土化研究,完善数感的测评方法,优化数感的课程设计,开展数感的教学实验研究。

Number sense is an important part of foreign mathematics education, and is also one of the ten core concepts in the Mathematics Curriculum Standards （2011 Edition）. Number sense is a multidimensional concept. From the perspective of information processing, number sense is the perception process of number which is non-precise and fast. Tetrahedral structure model of the number sense is constructed based on the integration of foreign structural models. Future research needs to focus on the localization of number sense, improve methods of evaluation, optimize curriculum design of number sense, and carry out teaching experimental study of number sense.
