4-5年级学生的空间表征与几何能力的相关性研究

本研究是“学生空间能力和几何能力关系”研究的一部分,以小学4、5年级学生为被试(共117人),以空问表征能力测验和几何能力测验为测验工具,初步探讨了学生空间表征与几何能力的关系。对数据结果的分析表明:①就总成绩而言,五年级学生的空间表在成绩明显高于四年级学生的成绩,但并不是空间表征的所有方面都存在着显著的年级差异;②就空间测验的总成绩而言,无论是四、五年级分别考察还是总起来考察,空间成绩与几何成绩之间的相关显著,但就各个分项而言,并不是空间测验的各项都与几何测验成绩有显著相关;学生的几何成绩在一定程度上可通过回归方程:Y_i=0.5736X_i+0.7635加以预测。

A PRELIMINARY STUDY ON THE CORRELATION OF SPATIAL ABILITY AND GEOMETRICAL ABILITY OF 4-AND 5-GRADE STUDENTS

In the present study, 117 4-and 5-grade students were tested with spatialtest and geometrical test,correlation between the students' performances on thesetwo tests was analysed. The results showed: 1) in general, as well as on thegeometrical test,the performances of the 5-grade students on the spatial test weresignificantly higher than that of the 4-grade students', but not in all aspectsof the spatial test; 2) either in total number of subjects or in 4-and 5-gradeseparately, the correlations between the performances of the two tests were sig-nificant; 3) the performances of students in the research on the geometrical testcan be predicted to a certain degree through the regression equation: Y ? =0.5736X_i+0.7635.
