This article stems from a research project conducted into possible factors involved in classroom learning. The project is based on a comparison of the academic performance of two groups within the subject of history teaching which, despite their morphological similarity, achieved different results. Analysis was carried out by comprehensively monitoring the individual activities of each student using the Moodle platform at the University of Barcelona. The project analyzed university entrance exams, academic performance in previous courses, academic backgrounds and other minor factors. The research concluded that none of these factors was decisive, meaning that other seemingly less important factors such as the emergence of leadership in the class and the management thereof during the academic yea must be studied in depth in order to illuminate the issue.
