数感是一种主动地、自学地理解数和运用数的意识,是对数与运算的一般理解,这种理解可以帮助人们用灵活的方法做出数学判断和为解决复杂问题提出有用的策略,也可以说数感是一种数学素养。有了这种素养,学生在学习数学知识时,就能左右逢源,得心应手。心理学研究表明,儿童有一种与生俱来的,以自我为中心的探索性学习方式。“数感”不是通过传授就能得到培养,而更要让学生在丰富多彩的校内外,课内外活动中感知、体验。因此,本文着重从现实情境的角度出发向学生渗透数感。
Sense of number is a conscious, self-conscious understanding of numbers and numbers, and is a general understanding of logarithms and operations that can help people make mathematical judgments in flexible ways and put forward useful strategies for solving complex problems , You can also say that a sense of number is a mathematical quality. With this literacy, students can be both good and bad when they learn math. Psychological research shows that children have an innate, self-centered, exploratory learning approach. “Sense of a few” can not be taught through training, but also to allow students in a variety of internal and external activities, classes and perceptions, experience. Therefore, this article focuses on the sense of reality to penetrate the number of flu.
