数学概念的网络化是数学素养的标志之一.所谓数学概念的网络化是指能够建立概念与概念之间的相互联系,在大脑中形成一种知识结构.要让概念内化为学生自己的知识结构,离不开对核心概念的多维度比较.这种多维度比较既反映在解题思路的比较上,又反映在会用多种方式来表征同一概念,如函数的表征方式有解析法、列表法、图象法.数学强调文字语言、图形语言与符号语言三者之间的转化,这种比较有利于在解决实际
The network of mathematical concepts is one of the hallmarks of mathematical literacy.The so-called network of mathematical concepts refers to the ability to establish the relationship between concepts and concepts in the brain to form a knowledge structure.To make the concept of the students themselves Knowledge structure is inseparable from the multi-dimensional comparison of the core concepts.This multi-dimensional comparison is reflected both in the comparison of problem-solving ideas, but also reflected in the use of a variety of ways to characterize the same concept, such as the way the function of the analytical method , List method, image method.Mathematics emphasizes the conversion between the text language, the graphic language and the symbolic language.This kind of comparison is advantageous in solving the reality
