Personal statistics on what each student have read and answered questions on is something we are constantly working on at Cortexio. Visualizing what is left, what has been done and how well a student knows each part of the course is an important part of the learning process.
When a student starts to reason about learning and learning herself; start thinking about working memory, study technique, forgetting curve, to achieve the knowledge goals in the course, it has a positive impact on the study results. In psychology / pedagogy it is called metacognition and is a subject where research is ongoing.
Recently we added a statistics page on Cortexio that shows an overview of recent activity with suggestions on what needs to be repeated.
