Thanks Mark for this nuanced response and I will follow through on those links – It would be helpful to think more about when messiness in education is good and helpful to learning (as in cMOOCs) and when not. Age and profession may have something to do with it, but probably also personality and personal circumstance? My students are adult, they’re in-service teachers… I keep wondering how much mess they can tolerate, or if it needs scaffolding. I also think about my next class which will be undergrad and how I might need to modify my pedagogy for them – so looking forward to exploring those links on teenage brains!
