| 摘 要： | 阐述传统测量方法在李克特量表分析中的固有缺陷,即测验依赖与样本依赖,项目间以及项目选项间计分方式的不合理性的基础上;通过研究实例说明Rasch模型中处理这些问题的方法,并阐述了所用方法的客观性。通过比较,说明Rasch模型是一种客观等距的测量模型。

| Abstract: | This paper talked about the inherent defect of the CTT in the analysis to the Liket Scales,that is test dependent and sample dependent,the irrationality of the scoring process between the items and between the options in the same item;And then,illustrated Rasch Model how to resolve these problems with real cases,and testify the objectivity of these methods.By comparing,Rasch Model is an objective and interval measurement model. |
