有人说,数感是指学生对数的敏感性;也有人说数感是学生对数值的一种直觉,对数学概念的直接反映。综合各种学者专家的观点,数感就是学生们对数和运算概念的一种主动地、自觉地感悟和理解以及运用这些知识的意识。在《数学课程标准》的总体目标中明确提出要使学生“经历运用数学符号和图形描述现实世界的过程,建立数感和符号感,发展抽象思维。”因此,数感是一个人数学素养高低的标志之一,也就是学生智慧与才能的体现。发展学生的数 Some people say that number sense refers to the sensitivity of the student logarithm; some say that number sense is an intuition of the student’s value, a direct reflection of the concept of mathematics. Combined with the opinions of various scholars and experts, the sense of number is the sense of initiative and conscientious perception and comprehension of students’ logarithm and operation concepts and the application of such knowledge. In the overall goal of “mathematics curriculum standards” clearly put forward to make students “experience the use of mathematical symbols and graphics to describe the real world process, the establishment of a sense of number sense and symbolic sense, the development of abstract thinking. ” Therefore, flu is a number of mathematical One of the signs of quality, that is, the embodiment of student intelligence and talent. Number of students to develop
