脑科学视野下数感的概念、生成及教学

Concept,generation and teaching on the number sense from the perspective of brain science

脑科学研究的相关证据为深入认识数感提供了新的视角,数感由数感觉、数符号、数能力和数思维4个要素组成,各要素作用于不同脑区.数感觉与生俱来,后天的数符号是数感发展的直接推力,数感发展是一个由低级向高级的发展过程.数感教学应立足于数感觉,建立数符号,发展数能力,锤炼数思维.

The relevant evidence of brain science provides a new perspective for further understanding of number senses.Number senses consists of four elements,such as number sense,number symbol,number ability and number thinking.Each element acts on different brain regions.The number sense is inherent,the acquired symbol of number is the direct thrust of the development of number sense,the development of number sense is a process from low level to high level.The teaching of number sense should be based on number sense,establish number symbols,develop number ability,and temper number thinking.
