Overview
Research in e-learning, as a variant of traditional instructional design research that has been conducted over the past decades, has a relatively well-established pool of extant studies and the resultant theory. Social network sites, and social media tools in general, while possessing many of the characteristics of the existing and well-researched field of computer-mediated communication, present a relatively new field of inquiry. The body of research that combines both e-learning and social media tools is even more limited than either of its constituent parts. As a result, a method that enables open and relatively unrestricted inquiry into a field of study that has an existing pool of experts but limited published research is beneficial to the body of work in the field.
