摘要: 采用探索性因素分析和验证性因素分析相结合的方法，构建了儿童数感的理论维度，编制了儿童数感评定量表，研究结果表明：数感是由数及其关系的知觉、运算结果合理性的评价、运算与估计的策略、数学问题结果的判断4个维度构成；儿童数感评定量表具有较高信效度，可以作为儿童数感的测评工具。Abstract: A children's number sense inventory is compiled and the theoretical dimensions for children's number sense are investigated in this study ,using exploratory factor analysis in combination with confirm‐atory factor analysis .The findings show that number sense is a structure model composed of four basic components ,i .e .perception of the numbers and their relationship ,evaluation of the reasonableness of the calculation result ,calculation and estimation strategy and determination of the results of the mathematical problems .The children's number sense inventory reported in this paper has considerably high reliability and validity and is ,therefore ,recommended to be used as an assessment tool of children's number sense .
