This is a relatively new mode of teaching in any widespread context, there is little in the literature to show how effective this approach has been. Most reports are anecdotal and limited in scale, although a recent study by KCL has been produced by Michael Detyna of the Centre for Technology Enhanced Learning. Empirical findings have only recently surfaced, so more research is necessary looking at diverse pedagogical situations and their impact on learner outcomes.
Optimum class size and the effectiveness of ISLA
There is some evidence that large cohort sizes and the original format of lecture based teaching should be avoided in a live multimodal approach. Classes could be adversely impacted by a purely live streamed version of a lecture.[2] This suggested that the ISLA methodology would be best suited to seminar based classes with more manageable cohorts of students unless different approaches to interaction and facilitation are managed.
“It is important to recognise that the experience of the lesson in the classroom compared to at home is very different. Classroom lessons work by the nature of their live interaction that is extremely difficult to replicate through live streaming, especially in large classes”[3]
