符号表示是人类文明发展的重要标志之一,数学课程的一个重要任务就是使学生感受和拥有使用符号的能力。新教材把发展学生的“符号感”作为一个重要的教学学习内容,符号是数学的语言,是人们进行表示、计算、推理、交流和解决问题的工具,作为数学知识的特点,数学知识尽量表现为形式化的符号。学习数学的目的之一是要使学生懂得符号的意义,会运用符号解决实际问题和数学本身的问题,培养和发展学生的符号感。
The symbolic representation is one of the important symbols of the development of human civilization. An important task of the mathematics curriculum is to enable students to feel and possess the ability to use symbols. The new textbook takes the development of student’s “symbol sense” as an important teaching learning content. Symbols are the language of mathematics. They are tools for people to express, calculate, reason, communicate and solve problems. As a feature of mathematical knowledge, mathematics knowledge Try to represent formal symbols. One of the purposes of learning mathematics is to enable students to understand the meaning of symbols, and to use symbols to solve practical problems and problems in mathematics, and to cultivate and develop students’ sense of symbols.
