“…For static student models, this process can be as straightforward as assessing the power of a model to predict successes and failures from a subset of student response outcomes. Validation has also been extensively studied for static learner models such as IRT, for which statistics such as person-fit and item-fit are a standard part of most software packages (see Khalid 2009 for a recent review). However, validation is more complex for dynamically changing learner models such as CT and CBM tutors.…”

In recent years, learner models have emerged from the research laboratory and research classrooms into the wider world. Learner models are now embedded in real world applications which can claim to have thousands, or even hundreds of thousands, of users. Probabilistic models for skill assessment are playing a key role in these advanced learning environments. In this paper, we review the learner models that have played the largest roles in the success of these learning environments, and also the latest advances in the modeling and assessment of learner skills. We conclude by discussing related advancements in modeling other key constructs such as learner motivation, emotional and attentional state, meta-cognition and self-regulated learning, group learning, and the recent movement towards open and shared learner models.
