项目反映理论在心理与教育领域已得到了广泛的应用,项目反映理论模型可以反映项目参数,被试能力与作答表现之间的关系,但是参数估计对于应用者来说存在一定的困难。现有的参数估计软件多是针对单维项目反映理论的,本研究尝试研究特质维度间的相关性对常用项目反映理论参数估计软件的估计精度的影响,探讨其适用性。
The project reflection theory has been widely used in the fields of psychology and education. The project reflection theory model can reflect the relationship between the project parameters, the ability of the participants and the presentation performance. However, the parameter estimation has some difficulties for the users. Most of the existing softwares for parameter estimation reflect the theory of single-dimensional project. This study attempts to study the influence of the correlation between the characteristics of the dimensions on the estimation accuracy of common parameters to reflect the theoretical parameter estimation software, and discuss its applicability.
