一、数感的内涵数感是一种主动地、自觉地理解和运用数与数量的态度与意识。这种态度与意识在很大程度上是一种直觉与敏感,它是在一定的数学情境中对数和运算的体悟与理解,以及运用数学知识的主动意识,是学生认知数学对象进而成为数学气质的心智技能,是学习数学的重要结构变量。因此,数感是学生数学素养的重要标志,它是建立明确的数概念和有效地进行计算等数学活动的基础,是将数学与现实问题建立联系的桥梁。数感也是一种数学化的思考,能用数学的方法提出问题、分析问题,并寻求解决实际问题的策略。
First, the number of sense of the number of sense is a sense of initiative and consciously understand and use the number and the number of attitudes and awareness. This kind of attitude and consciousness is a kind of intuition and sensitivity to a large extent. It is the comprehension and understanding of logarithm and operation in a certain mathematical situation, as well as the active consciousness of using mathematical knowledge, Mathematical temperament mental skills, is an important structural variable to learn mathematics. Therefore, the sense of number is an important symbol of students’ mathematical literacy. It is the basis for establishing a clear concept of numbers and mathematics activities such as computing effectively. It is also a bridge connecting the mathematics with the reality. Sense of number is also a mathematical thinking that can be used mathematical methods to ask questions, analyze problems and seek solutions to practical problems.
