Research Framework - Modeling and Design

Student Modeling

This area includes any research about the design or modeling of knowledge structure or skills. The research may be about abstractly conceived knowledge or skills or knowledge or skills as they pertain to specific tasks. The research may concern substantive or psychometric modeling, or both. The psychometric model of ability might be either multidimensional, unidimensional, or some combination thereof; and the scale for the statistical model could be either continuous, discrete, ordered categories, latent classes, or a complex combination of two or more of these.

This research is frequently conducted in tandem with task development because linking the two is at the heart of all assessment research. Verbal-protocol analysis, in which an examinee's knowledge and skills are studied as the examinee works on an assessment task, is one example of such linked research.
