上海初中毕业生学业水平考试数学测试的实证性因素分析

Confirmatory factor analysis of the Math tests for Shanghai junior high graduate students

实证性因素分析的运用越来越广泛,也已成为教育与社会心理领域中最常用的统计方法.尝试运用实证性因素分析的方法,对近两年的上海初中毕业生学业水平考试数学测试的构想效度进行分析,从模型量化的角度论证了这两年测试生在数学测试上的成绩体现了试卷结构设计的四维结构.

In the areas of education and social psychology, the confirmatory factor analysis （CFA） is frequently used. Using a CFA model, this research examines students＇ responses to the mathematics tests for Shanghai junior high school graduate students＇ performance assessment and investigates the structure validity of the tests. The framework of four dimensions is identified, then comes the analysis of the item response data. It is demonstrated that the CFA is a powerful tool for extracting information from a limited number of item responses, and the research confirms the structure of mathematics tests with four dimensions.
