摘要
定义了属性之间菱形层级结构的概念.在某种给定的评分方式下,假设属性之间没有补偿作用,讨论独立型、菱形层级结构对应的多级评分认知诊断测验蓝图设计问题,分别构造出相应的完备Q阵.
Given a polytomous scoring rule,suppose that there is no compensation among the attributes,the design of polytomous cognitive diagnostic test blueprint for the independent and the rhombus attribute hierarchies after defi-ning the rhombus type and the maximum set of non-comparable attributes is discussed. The structures of the test Q matrix,named as perfect Q matrix,for the 2 types are obtained. The perfect Q matrix contains the fewest columns and is the bijective mapping between the set of the knowledge states and the set of the expected response patterns The perfect Q matrix for the polytomous,which is restricted with its rank or the number of the maximum set of non-comparable attributes in the basic attribute hierarchy,is different from that for the dichotomous.
