IntrospectiveViews

IntrospectiveViews is a rich-interaction interface that allows users to inspect and alter their user models. It offers users an overview over all terms present in their model, it allows for zooming into different parts of the model, it allows to filter terms according to different criteria, and  it will provide details, for instance additional information on a term or information about how the system determined the user interest in a term, on demand. IntrospectiveViews also allows revealing relationships among the items, supports browsing through the history of the user model, and allows exporting the entire model or parts of it.

Parallel IntrospectiveViews

Parallel IntrospectiveViews is a novel visual metaphor and an interface for visualization of multiple open student models. The interface displays not only the student’s own model, but also the models of her peers and the entire class.

Progressor

Progressor is a newer generation of Parallel IntrospectiveViews. This version is intended to make a stronger impact on the student’s motivation to compete with other students and to progress on the educational content. In addition to the one-to-one comparison introduced in its predecessor, the system allows viewing learner models of multiple peers at the same time. It also allows sorting peers by either by the overall progress or by the progress in a specific topic and shows the student’s position in the ranking.
