During recent years there has been a significant increase in the usage of technological tools in general, and in academic teaching in particular. Many programs have been developed, including online teaching and online courses at educational institutions. In this paper, we discuss the Facebook social network and its use at the University. The research shows that Facebook groups are used to facilitate communication between students, to foster a positive social climate, to create dialogue and to share learning material among group members. The paper examines students' achievements and their satisfaction with the impact of the Facebook group on the academic course, in order to examine whether the use of Facebook groups in academic courses can improve course quality and students' achievements.
