小学低段数学符号意识测评指标体系的初步构建

A Preliminary Construction of A System of Measurement Indicators for Mathematics Symbols Awareness in Lower Grades of Elementary School

数学符号意识是小学生数学抽象思维的第一步,是人的抽象思维形成的基础,也是数学核心素养的重要组成部分。从小学低段数学符号意识内涵的再认识入手,通过实证研究初步构建并验证了小学低段数学符号意识的测评指标体系(即3个一级内涵维度指标:数学符号的抽象、数学符号的识记和数学符号的应用,7个二级行为因素指标,以及各指标的权数),该测评指标体系为小学生数学符号意识和抽象思维的培养提供了具体参考指标。

Awareness in mathematics symbols is the first step of the mathematical abstract thinking of elementary school students, is the basis of the formation of abstract thinking of humans, and is an important part of the core mathematics literacy. The authors re-examined the connotation of awareness in mathematics symbols in lower grades of elementary school, and on the basis of empirical data, constructed and verified a system of measurement indicators consisting of 3 primary indicators in the content dimension （namely, the abstraction, memorization and application of mathematics symbols） and 7 secondary indicators of behavioral factors, and weight coefficient. The system of measurement provides specific reference indicators for the fostering of elementary school mathematical symbols awareness and abstract thinking.
