University tutoring consists of a set of heterogeneous actions aimed to support students, upon entering the University and throughout their academic life. The tutoring implements the resources needed to cope with possible difficulties in each phase of the training process. It also provides information and advice to better address the study course, prepares paths for the recovery of learning gaps, and provides assistance for the preparation of the thesis. Its main purpose is to remove any possible obstacles to a profitable attendance at courses, also through initiatives related to the attitudes and needs of individuals. The research group of University of Turin has designed and developed a model of online tutoring, carried out via an online Moodle platform integrated with a web conference service for the Disciplinary Tutoring of the University of Turin. The main aim of the project, called TutoratoOnline, is to reduce the number of students starting the second academic year with a low number of passed exams, by helping students with the lessons they find more difficult. Through the platform, various and many synchronous and asynchronous tutoring activities were offered to students. The aim of this paper is to discuss and analyze the multiple tutoring activities carried out through the platform and the multiple teaching strategies used, and to discuss how their variety is associated with a greater students engagement.
