基于属性蕴含的Q矩阵理论

认知诊断(CD)是认知心理学与心理和教育测量学相结合的前沿研究领域.在属性间约束关系的Q矩阵理论中,其认知模型仅考虑了属性集与属性间的层级关系,忽略了属性间可能存在非层级关系的蕴含关系.该文探讨基于属性蕴含的Q矩阵生成,以及属性蕴含关系的挖掘.研究成果扩充了现有Q矩阵理论,完善认知诊断的理论、方法和应用.

Q Matrix Theory Based on Attribute Implication

Cognitive diagnosis is a cutting-edge research integrated with cognitive psychology,psychometrics and education measurement.In the Q matrix theory in which the constraint relationships of attributesare considered,the cognitive model of the theory can be described by a set of attributes and the hierarchical relations among them.Nonetheless,the model ignores the possible non-hierarchical implication relations.The paper is aimed to explore the generation of the Q matrix and the method to mine out theattribute application.The research project is also expected to advance the theories of cognitive diagnosis and to promote its pragmatic application.The research will have a positive academic value of expanding the field of Q matrix theory.
