Communication is one of the fundamental elements required for facilitating learning. It is present in the work of (Vygotsky 1978) and more recently (Wenger 1998). These authors are concerned with understanding learning and explaining it. Others have focused their attention on the development of frameworks to facilitate learning. In particular, work related to the introduction of information technology (IT) into the learning domain (e-learning) is exemplified by (Laurillard 1993) and (Salmon 2000). This paper looks at online communication as the link between established theory of learning and literature on e-learning. This work is related to action research data that was collected by the authors on a course using the blended learning mode of delivery. The results suggest that communication is both a challenge and an enabler for facilitating a successful blended learning course.
