基于CFA视角的高考数学试卷结构的多维度研究

Multidimensionality Study of Test Structure: Based on the Confirmatory Factor Analysis of Mathematics Test for College Entrance Examination

本文利用验证性因素分析(CFA)对一份高考数学试卷预设能力维度模型与实测数据进行拟合,给出了试题与其所反映的潜在能力维度之间的关系。分析结果表明,试题所反映的能力维度基本符合预设的目标,但试题所考核的能力目标并不十分明显,试题质量还需要进一步提升。分析也表明,验证性因素分析是一种有效的试卷能力维度分析方法。

This paper uses confirmatory factor analysis (CFA) to fit the multidimensional ability model of a college entrance examination mathematics paper with the measured data, and gives the relationship between the test item and the potential ability dimension reflected. The analysis results show that the ability dimension reflected by the test is basically in line with the goals, but the ability goal assessed by the test is not very obvious, the quality of the test still needs to be further improved. The analysis also shows that confirmatory factor analysis is an effective method to analyze the ability dimension of test paper.
