I've read the articles they published this year, but I still thought this was a great presentation to watch to see the sort of research happening and the findings from the research. Amd to remind me of what I forgot!
A few of us where I work are quite excited by the Course Archetypes, and using them [when we upgrade!] to look across our courses and see what we find. Before we heard of the Course Archetypes in v4.3.4 we were thinking of trying to analyse our courses ourselves and do something similar. Thankfully Bb has done the work for us!
