本研究的目的在于应用Rasch模型编制和分析数学入学准备测验,从而分析Rasch模型的有效性和优势。自编数学入学准备测试,对150名平均年龄为6 6岁的儿童进行测查,应用Rasch模型对题目和评分等级做出修正并分析结果。结果表明修正后的测试具有较好的信效度,较好地拟合了Rasch模型,评分等级设置合理,测试的整体难度相对较低。儿童的Rasch分数和性别无关,但受到年龄、家庭社会经济地位的影响。相对于经典测量理论而言,应用Rasch模型进行入学准备测试的编制和分析具有优势。
The purpose of this study is to use the Rasch model to prepare and analyze math entry preparation tests to analyze the validity and advantages of the Rasch model. A self-made math test was conducted to test 150 children aged 6 6 years old. The Rasch model was used to correct the questions and grades, and the results were analyzed. The results show that the modified test has good reliability and validity, and the Rasch model is well fitted. The rating scale is set reasonably and the overall difficulty of testing is relatively low. Children’s Rasch scores have nothing to do with gender but are influenced by age and family socio-economic status. Compared with classical measurement theory, it is advantageous to apply Rasch model to prepare and analyze entrance preparation test.
