摘　　要：教育认知诊断基于被试的作答反应估计其知识状态从而进行分类.尽管给定属性及其层级关系,其知识状态集合是唯一的,但对此并未形成共识.如有的软件包认为同一属性层级关系可对应2种不同的知识状态集合;有的研究仅仅给出属性及其层级关系的知识状态集合的真子集.针对这些情况,该文从理论上和应用上进行了分析,并给出修正的建议.Educational cognitive diagnosis determines which group an examinees is belonged to according to the estimated his/her knowledge states based on the responses on a test.After determining the attributes and their hierarchical relationship,the set of their knowledge states is unique,but there is no consensus on this.For example,some software considers that the same attribute hierarchy relationship can correspond to two different sets of knowledge states.Some studies only give the proper subset of the knowledge state set of attributes and their hierarchical relationships.In view of these situations,the theory and application are analyzed,and some suggestions for correction are given.
