Discussing the Development Tendency of Cognitive Diagnosis from the Perspective of New Models

Abstract

Cognitive Diagnostic Theory(CDT) has a history of more than fifty years. CDT is the wedding of cognitive psychology and psychometrics. One of the cores of CDT is the development of Cognitive Diagnostic Models(CDMs). This paper firstly indicates at least four aspects of shortages including fitting the individual cognitive processes, data processing, operable data types, and analysis of the whole test using a unique CDM. Then, to make up for aforementioned deficiencies, the detailed introduction on the new CDMs and their theoretical thoughts are proposed. These new CDMs are multiple-choice CDM, multiple- strategy CDM, continuous response CDM, and log-linear CDM. Finally, based on the new models, the development tendency of current cognitive diagnosis is summarized and some inspirations are offered to cognitive diagnostic researcheres and practitioners.
