中文摘要：
Q矩阵和Q矩阵理论是认知诊断中一对容易混淆的概念,一方面需要强调它们的差异,另一方面对Q矩阵理论做一些补充,比如在一定条件下,多级评分的认知诊断中测验蓝图的设计原理.根据实测数据对测验蓝图Q矩阵修正的设想,以及认知诊断模型和多维项目反应模型的联系.
英文摘要：
Q matrix and Q matrix theory are easy confusable.The difference between them is emphasized and the complement of Q matrix theory is given in this note.Especially,how to design the blueprint for the cognitive diagnosis with the 0-1 scoring or polytomous scoring is discussed.Moreover,there is a scheme for modification of the test Q matrix and an idea of how to use the multidimensional item response model to analyze the data with large granularity of the attributes in the part of discussion of the note.
