Friction Radar is a Moodle course report that surfaces early, aggregated signals of learning friction. It analyses activity logs and standard course data over a rolling six-week window and visualizes twelve friction indicators (plus an overall score) in a friction clock designed for reflection and improvement, not learner evaluation. The report is strictly course-level and anonymized; it does not store or display individual learner data and runs heavy calculations offline via scheduled cache warmers for performance.
