关于数学符号感及其发展策略的探究

Investigate on Sense of Mathematical Symbols and Its Development Strategy

数学符号感是对符号模式和符号关系的意识,并用这种意识灵活解决数学问题的能力。《全日制义务教育数学课程标准(实验稿)》强调发展学生的符号感,就是从具体问题中使学生能够抽象出变化规律和数量关系,并会用数学符号表示;深刻理解数学符号所表示的数量关系,并进行符号间的变换;对于用数学符号所表示的问题能选择合适的方法解决。发展和培养数学符号感的关键在于:了解数学符号的发展历史和特点,在实践活动中发展数学符号感,在具体情景中发展数学符号感,在实际应用中发展数学符号感。

Mathematics "sense of symbol" is the consciousness of symbol relationship and symbol mode, and the ability to use this consciousness to solve mathematical problems flexibly. The Curriculum Standard emphasizes that the development of students’ sense of symbols is to enable students to abstract the quantitative relationship and change rules from specific situations, and express them with symbols. It requires students to understand the quantitative relationship represented by symbols, and carry out the conversion between symbols. To a certain extent, students can choose appropriate procedures and methods to solve the problems represented by symbols. The key to cultivate and develop mathematical "sense of symbol" lies in: first, understanding the characteristics and development history of mathematical symbols, and developing mathematical "sense of symbol" in practice;second, developing mathematical "sense of symbol" in specific situations;third, developing mathematical "sense of symbol" in practical applications.
