以"进位计数制"为测验内容,运用基于多级评分的广义距离法(简记为GDD-P)进行认知诊断,得到被试的属性掌握模式,这不仅验证了可以对多级评分测验进行认知诊断,且提供了一种多级评分认知诊断的应用范例.
Using a polytomous extension of the generalized distance discriminating method( GDD-P) to diagnose students' mastery of carrying notation,the students' attribute mastery patterns are obtained. The study indicated that not only examinees' attribute pattern could be diagnosed with polytomous response,but it also provides an example for cognitive diagnosis with polytomous response.
