Facebook is social media that is ubiquitously used in higher education contexts by both staff and students. It provides a platform for student networking and expression. The authors illuminate how pre-service teachers in an Australian university, undertaking undergraduate units, use Facebook as a student-initiated social media community. Although an increasing number of research studies have investigated student use of social media in higher education, this is an under-theorised area. In particular, little has been written about the student-initiated use of Facebook as a commentary on the activities running simultaneously to formal online learning programmes in universities. Data drawn from 15 semi-structured interviews support an investigation into student Facebook use. Findings highlight that student-driven Facebook sites have a range of purposes and offer ever-present access to a relational community online, although this can sometimes be problematic. When emotional support is not forthcoming from academics or there is disenfranchisement in formal learning spaces, membership in student-initiated learning communities can afford immediacy, informality, influence and shared emotional connections.
