Progressor: Personalized visual access to programming problems

This paper presents Progressor, a visualization of open\ud student models intended to increase the student’s motivation to progress on educational content. The system visualizes not only the user’s own model, but also the peers’ models. It allows sorting the peers’ models using a number of criteria, including the overall progress and the progress on a specific topic. Also, in this paper we present results of a classroom study confirming our hypothesis that by showing a student the peers’ models and\ud ranking them by progress it is possible to increase the student’s motivation to compete and progress in e-learning systems
