This paper explores how technology, and specifically the application of social media, in the English as a foreign language (EFL) classroom is changing how language is taught. The paper begins with a depiction of computer-assisted language learning (CALL) and how technology has generally been employed in EFL classrooms in the past few decades. This critical appraisal, which provides the context for the paper, assesses how successfully technology has been viewed in relation to language teaching and learning and how it has developed up to the present day. The focus then moves to social media apps and mobile technology as a contemporary form of CALL. The discussion considers the ways in which social media is used in language classrooms and more importantly the things it can offer the EFL teacher and learner. Importantly, the paper concludes by proposing ways in which these types of technologies can be better incorporated across cultures and contexts to promote EFL teaching and learning.
