数感作为一个全新的学习内容,在《全日制义务教育数学课程标准》中首次提出,并指出数感的具体体现是:“理解数的意义;能用多种方法来表示数;能在具体的情境中把握数的大小关系;能用数来表达和交流信息;能为解决问题而选择恰当的算法;能估计运算的结果,并对结果的合理性做出解释。”由此可知,数感是学习数学的重要结构变量,集中表现为:对知识教学的充分感知,对思维训练的快速反应,对个性教养的深刻感受。
As a new learning content, Sense of Number is first put forward in the standard of full-time compulsory education mathematics curriculum. It points out that the sense of Sense of Number is: "to understand the meaning of number; to use a variety of ways to represent numbers; In specific situations, we can grasp the relationship between the number of numbers, we can use the number to express and exchange information, we can choose the appropriate algorithm to solve the problem, we can evaluate the result of calculation and explain the rationality of the result. , Sense of number is an important structural variable in learning mathematics, focused on: the full awareness of knowledge teaching, rapid response to thinking training, personal feelings of profound feelings.
