小学低段数学符号意识的培养策略研究

Study of the Strategies in Cultivating Mathematics Symbol Sense at Lower Elementary School Level

培养和发展小学低段学生数学符号意识是发展学生数学核心素养的基础,是培养学生数学抽象思维的第一步.从小学低段数学符号意识的可操作性定义入手,结合学生的认知规律和教师的教学观,围绕小学低段数学符号意识的内涵本质特征,分别从数学符号的抽象、识记和应用去探讨小学低段数学符号意识的培养策略,这有利于小学生对数学符号本质的认识、理解和掌握,有利于小学生数学符号意识的形成和发展,这为学生符号意识的培养和数学抽象思维的发展提供了新的路径.最后通过微型教学实验验证该培养策略的可行性、操作性和有效性.

Cultivating and developing mathematics symbol sense of students at lower elementary school level is the basis for cultivating students＇ abstract thinking and an important step for developing students＇ core literacy in mathematics. Starting with an operational definition of mathematics symbol sense and encompassing the content dimensions of mathematics symbol sense at lower elementary school, and combined with students＇ cognitive regularity and teachers teaching view, this paper explores the strategies in cultivating mathematics symbol sense at lower elementary level from the abstraction, identification and application of mathematics symbols. It is conducive for students to understand the nature of mathematical symbols, and it is conducive to the formation and development of students＇ mathematical symbols sense. It provides a new path for the development of cultivation and students＇ abstract thinking. Through experimentation utilizing micro-teaching, the feasibility, operation and effectiveness of the cultivation strategies are verified.
