数感作为数学能力的重要组成部分,它的本质是一种类化了的个体数学经验,是个体进行数学活动的产物。数感还是一种能力。首先,数感不是先天的,它是主体在后天的数学活动过程中形成和获得的。数感作为一种个体的经验,不可能像直接陈述知识一样以物化的形式传递。数感更多地表现为主体在数学活动中通过学习、积累、体验而形成的主体能力,是主体自身积极积累经验,主动建构知识的结果。其次, As an important part of mathematical ability, the sense of number is a kind of individualized mathematical experience, which is the product of the individual’s mathematical activity. Feeling is still a kind of ability. First of all, the sense of the number is not inherent, it is the subject formed and acquired in the process of mathematics after acquired. Feeling as an individual experience can not be as materialized as the direct presentation of knowledge. Sense of the number of more performance for the main activities in mathematics through learning, accumulation, experience and the formation of the main ability is the main positive accumulation of their own experience, take the initiative to build knowledge of the results. Second,
