New Q-matrix validation procedures

2017
The primary purpose of cognitively diagnostic assessment (CDA) is to provide useful information about students’ learning needs. The attributes (i.e., latent skills) possessed by examinees can be uncovered based on examinee responses to test items primarily in conjunction with cognitive diagnosis models (CDMs).

Priority attribute algorithm for Q-matrix validation: A didactic

Behavior Research Methods
The Q-matrix is one of the core components of cognitive diagnostic assessment, which is a matrix describing the relationship between items and the attributes being assessed. Numerous studies have shown that inaccuracies in defining the Q-matrix can degrade parameter estimation and model fitting results.

Theory of the Self-learning Q-Matrix.

Bernoulli : official journal of the Bernoulli Society for Mathematical Statistics and Probability
Cognitive assessment is a growing area in psychological and educational measurement, where tests are given to assess mastery/deficiency of attributes or skills. A key issue is the correct identification of attributes associated with items in a test. In this paper, we set up a mathematical framework under which theoretical properties may be discussed ...
