Case teaching is not just for the classroom – increasingly, you can (and some schools do) offer discussion-based (or, at least, interaction-courses online.) My buddy Bill Schiano and I wrote a long note on how to do this for Harvard Business Publishing back in 2017 – and I then completely forgot about it.
Recently, I rediscovered it online, published by HBP – so, here goes: Schiano, Bill and Espen Andersen (2017): Teaching with Cases Online, Harvard Business Publishing. Enjoy. (More resources available at the HBP Teaching Center page.)
Incidentally – should you (as a school) consider doing courses this way, beware that this is not a cost reduction strategy. You probably will need to pay the online teachers more than those doing regular classrooms, simply because it is more work and quite a bit more design, at least in the beginning. But it may be an excellent way of reaching student groups you otherwise could not reach, for geographical or timing reasons.
