Purpose Since 2004, the Korea Institute of Medical Education and Evaluation has been responsible for the evaluation and accreditation of medical schools in Korea. The 2nd cycle of evaluations was conducted from 2007 to 2011. The present study aimed at testing the goodness of fit of the items used in the 2nd cycle of evaluation and accreditation based on the Rasch model. Methods Dichotomous data on 40 medical schools were analyzed using Winsteps, a tool based on the Rasch model that includes goodness-of-fit testing. Results Two of the 109 items had an outfit mean square exceeding 2.0. The other 107 items showed a goodness of fit in the acceptable range for the outfit mean square. All items were in the acceptable range in terms of the infit mean square. Furthermore, 1 school had an outfit mean square exceeding 2.0, while all schools were in the acceptable range for the infit mean square. An outfit mean square value over 2.0 means that an item is a outlier. Therefore, 2 items showed an extreme response relative to the overall response. Meanwhile, the finding of an outfit mean square over 2.0 for 1 school means that it showed extraordinary responses to specific items, despite its excellent overall competency. Conclusion The goodness of fit of the items used for evaluation and accreditation by the Korea Institute of Medical Education and Evaluation should be checked so that they can be revised appropriately. Furthermore, the outlier school should be investigated to determine why it showed such an inappropriate goodness of fit.

基于Rasch模型的韩国医学教育与评估学院在第二轮医学学校评估与认证中使用的项目的合适性

目的自2004年以来,韩国医学教育与评估学院一直负责韩国医学院校的评估和认证。第二轮评估于2007年至2011年进行。本研究旨在测试基于Rasch模型的第二轮评估与认证中所使用项目的合适性。方法使用Winsteps分析40所医学院校的二分数据,Winsteps是基于Rasch模型的工具,其中包括拟合优度检验。结果109件物品中有2件的服装均方值超过2.0。其他107个项目的合身度在服装均方值的可接受范围内。就适应均方而言,所有项目均在可接受的范围内。此外,有1所学校的服装均方值超过2.0,而所有学校的均方差均在可接受范围内。服装的均方值超过2.0表示项目是异常值。因此,有2个项目相对于总体响应显示出极端响应。同时,发现一所服装的均方根大于一所学校的2.0,这意味着,尽管其整体能力出色,但它对特定项目表现出非凡的反应。结论应该检查韩国医学教育与评估学院用于评估和鉴定的项目的合适性,以便对它们进行适当的修改。此外,应该对离群学校进行调查,以确定为什么它显示出这种不合适的拟合优度。相对于总体响应,有2个项目显示出极端响应。同时,发现一所服装的均方根大于一所学校的2.0,这意味着,尽管其整体能力出色,但它对特定项目表现出非凡的反应。结论应检查韩国医学教育与评估学院用于评估和鉴定的项目的合适性,以便对其进行适当修订。此外,应该对离群学校进行调查,以确定为什么它显示出这种不合适的拟合优度。相对于总体响应,有2个项目显示出极端响应。同时,发现一所服装的均方根大于一所学校的2.0,这意味着,尽管其整体能力出色,但它对特定项目表现出非凡的反应。结论应检查韩国医学教育与评估学院用于评估和鉴定的项目的合适性,以便对其进行适当修订。此外,应该对离群学校进行调查,以确定为什么它显示出这种不合适的拟合优度。结论应该检查韩国医学教育与评估学院用于评估和鉴定的项目的合适性,以便对它们进行适当的修改。此外,应该对离群学校进行调查,以确定为什么它显示出这种不合适的拟合优度。结论应检查韩国医学教育与评估学院用于评估和鉴定的项目的合适性,以便对其进行适当修订。此外,应该对离群学校进行调查,以确定为什么它显示出这种不合适的拟合优度。
