基于等级反应模型的CAT系统的研究和开发

Research And Development On CAT System Under Polychotomous Scoring Model

计算机化自适应测验是现代测验研究中的一个重要领域,而目前大多研究都基于0-1评分模型,适用范围不广。本文对Samejima等级反应模型进行探讨和研究,运用DELPHI开发研制多级评分计算机化自适应测验。

Computerized Adaptive Testing is the important part of the modern testing research,however,most of the researches are based on dichotomous scoring model,the extent of application is not extensive,so we research on CAT under polychotomous scoring model.We have developed CAT based on Samejima Graded Response Model with Delphi and Access.
