小学生几何直观能力测评模型的构建探究

Study on Constructing Assessment Model of Geometrical Intuition Ability for Elementary School Students

运用文献法以及专家咨询、学生测试以及教师问卷等实证方法,首次探索小学生几何直观能力的操作性定义及测评指标.利用因子分析法与专家评分方法,尝试构建了小学生几何直观能力测评模型：Y（28）0.3A（10）0.3B（10）0.4C.经初步检验,该测评模型可靠、可操作,可作为测评小学生几何直观能力的工具.

Through literature study and employing the empirical research methods including expert consultation, students＇ testing, teachers＇ questionnaire, etc, the operational definition and assessment indicators of the geometrical intuition ability for elementary school students were established. Furthermore, the assessment model of the geometrical intuition ability for elementary school students, Y = 0.3A ＋ 0.3B ＋ 0.4C, was constructed by factor analysis and analysis of experts＇ rating scores. Through validation, the assessment model could be a valid and operational tool to assess the geometrical intuition ability of elementary school students.
