The document describes a study that analyzed student activity log data from the Moodle learning platform. Metrics like mean time between access, total logged-in time, and total activity rating were calculated from the log data for each student. A decision tree model was generated to map these metrics to student final grades. The results showed that total activity rating was the strongest predictor of grade in the decision tree. The model achieved an accuracy of 62% in predicting student grades based on their Moodle activity.
