Research Framework - Modeling and Design

Modeling Student-Task Interaction

This research area studies the linking of student models with task performances and the design or modeling item response functions (IRFs). An IRF is a mathematical model that relates a model for examinee ability with a task model, so that the result tells the probability of each of the different scores that are possible on a task, depending on a particular value of examinee ability. In other words, this research area concerns modeling the interaction of ability and task models. Consequently, such research often also includes research on modeling tasks, modeling ability, or both, in addition to the modeling of the interaction of the two.
