The research presented in this paper is driven by a desire to increase student interaction and engagement in lecture discussion. The issues relating to the use of Twitter to achieve this goal are outlined. At the outset, the importance of interaction and engagement in learning is established, drawing on a number of educational theories and previous research in the area. Following this, the necessity for action is recognised by critiquing lectures as a forum for this standard of learning. The researcher presents technology as a means to increase student interaction, beginning with Audience Response Systems (ARS). A summary of research carried out on ARS is examined to provide a basis for integrating technology. Following this a review of experiments conducted using Twitter is carried out. Although there is a dearth of research in this area, these provide some insights into the use of this technology and its integration into education. The paper then examines student adoption of Twitter as a means of engagement, outlining the strengths, weaknesses and opportunities for the future. Finally emerging uses of the Twitter platform are examined, allowing the reader glimpse student hopes for future integration.
