Learning analytics in competitive programming training systems
In this paper we discuss the use of Analytics in oii-web, an online programming contest training system. We first provide an overview of the challenges in training for programming contests. Then we discuss the data collected in these years using oii-web, a platform devoted to the training of students for the Italian Olympiads in Informatics (Olimpiadi Italiane di Informatica-OII), and analyze them comparing two distinct groups of users in two distinct platforms built on oii-web, one devoted to students and one to their teachers.
