怎样培养学生的符号意识,提高学生的数学素养呢?本文结合自己十几年的教学经验,谈几点认识:一、结合概念、命题公式的教学,培养学生的符号意识概念、命题、公式是数学课程内容的重要组成部分,是数学教学的重点,与数学符号的表达和使用密切相关。教师在教学中要注意让学生正确理解符号的内涵,正确理解使用符号所表示的概念。例如:教学一年级上册第三单元1~5的认识,“理解符号<,=,>”的含义时,先让学生用自己的话说
How to cultivate students ’awareness of symbols and improve their mathematical literacy? This article combined their own teaching experience of more than 10 years to talk about a few points: First, combining concepts and propositional formulas to develop students’ concepts of symbolic awareness, propositions and formulas are An important part of mathematics curriculum content is the focus of mathematics teaching, which is closely related to the expression and use of mathematical symbols. Teachers in teaching should pay attention to enable students to correctly understand the meaning of symbols, the correct understanding of the use of symbols represented by the concept. For example: teaching first grade third unit 1-5 understanding, “understanding symbol <, =,> ”, let students in their own words
