Examining Uncertainty and Misspecification of Attributes in Cognitive Diagnostic Models
In recent years, cognitive diagnostic models (CDMs) have been widely used in educational assessment to provide a diagnostic profile (mastery/non-mastery) analysis for examinees, which gives insights into learning and teaching. However, there is often uncertainty about the specification of the …

Nonlinear penalized estimation of true Q-matrix in cognitive diagnostic models
A key issue of cognitive diagnostic models (CDMs) is the correct identification of Q-matrix which indicates the relationship between attributes and test items. Previous CDMs typically assumed a known Q-matrix provided by domain experts such as those who developed the questions. However, …

Detection of Attribute Hierarchies and Classification Accuracy: the Value of the Hierarchical Diagnostic Classification Model in Formative Assessment Practices
… areas a student is excelling or struggling in, cognitive diagnostic models are emerging as potentially effective and efficient tools. Despite the value of diagnostic models, there are concerns regarding the application of these models when as learning hierarchy is present or theorized; applying …

Test Discrimination and Test Construction for Cognitive Diagnosis
"While Cognitive Diagnostic Models, CDMs, can be useful in the analysis and interpretation of existing tests, little has been developed to specify how one might construct a good test using aspects of the CDMs. This paper discusses the derivation of a general CDM index and three attribute level CDM …

The application of a cognitive diagnostic model on the test of practical Chinese
Cognitive Diagnostic Models (CDMs) are frequently used in the second language proficiency exams to analyze test takers’ strengths and weaknesses. This study retrofits a CDM known as the Fusion model onto a non-diagnostic test data from the reading comprehension test of the Test of Practical Chinese …

Maximizing the Potential of Multiple-choice Items for Cognitive Diagnostic Assessment
When applying cognitive diagnostic models, the goal is to accurately estimate students’ diagnostic profiles. The accuracy of these estimates may be enhanced by looking at the types of incorrect options a student selects. This thesis research examines the additional diagnostic information available …

Identifiability for latent class models
Despite the fact that latent class models have been widely applied and appeared to perform well in various applications, it is well known that inference for latent class models is challenging due to the potential nonidentifiability of the underlying model parameters. In other words, multiple or …

Bridging the gap between research and practice: construction and validation of a CDA-informed English reading test for China's twelfth graders
… success. Although recent research advances in cognitive diagnostic assessment (CDA) move in this direction, most CDA studies of second language (L2) reading tend to identify examinees' mastery of skills by using the existing tests that were not originally designed for diagnostic purposes (e.g., …

Implementing a cognitive diagnostic assessment in an institutional test: a new networking model in language testing and experiment with a new psychometric model and task type
This dissertation is based on two major projects, cognitive diagnostic model comparison and implementing cognitive diagnostic assessment in an institutional test. In the first project, five cognitive diagnostic models are empirically compared for language test data under a unified general modeling …
