试卷结构的多维度研究:主成分分析的视角

Multi-Dimensional Research on the Structure of Test:the Perspective of Principal Component Analysis

试卷结构分析是检验试卷质量的一个非常重要的方面。利用主成分分析技术,对一份综合了数学和英语试题的分类考试试卷的结构进行多维度分析。结果显示:试卷存在两个学科维度,且两个学科维度的试题相互分离。该结果与探索性因素分析结果具有一致性,验证了主成分分析方法对试卷结构多维度分析的有效性。

Test structure analysis is a very important aspect of evaluating the quality of test.Based on the component analysis,a multi-dimensional analysis of the structure of college entrance examination that combines Mathematics and English test questions is carried out in this paper.The results show that the test has two disciplinary dimensions,which is consistent with those of exploratory factor analysis and verifies the multi-dimensionality of the test structure.
