The rapid adoption of social media technologies has resulted in a fundamental shift in the way communication and collaboration take place. As staff and students use social media technologies in their personal lives, it is important to explore how social media technologies are being used as an educational tool. The aim of this paper is to analyse the role of social media, in particular, Facebook, as an educational tool in higher education. Through a review of the literature, this paper explores the myriad ways in which Facebook is being used as an educational instrument for learning and teaching. Multiple benefits of Facebook usage for learning and teaching have been identified such as increased teacher-student and student-student interaction, improved performance, the convenience of learning and higher engagement. The paper also highlights the potential problems and limitations of Facebook usage ranging from educators' dominance to privacy concerns. Finally, Facebook usage guidelines that can be adopted by educators to encourage social media adoption are proposed. As social media usage continues to grow in higher education, future empirical research is warranted.
