I can't think of any academic environment I've been involved with that hasn't attempted some form of professional learning community. Alexandra Mihai writes, "They are based on the idea of creating a space for reflective practitioners to exchange and crowdsource ideas and support each other in their practice." We see them where I work in Slack forums, gcCollab discussions, seminars and workshops, and more (and these, I might add, have been a lot more active at NRC during the pandemic, and I hope we don't lose them). Minhai says successful professional learning communities depend on four factors: being a safe space, validation by peers, crowdsourcing ideas, and accountability. If I had to create my own list it would be: tools that work, practical value, timely response, and whole-of-enterprise (and beyond!) scope.
