I recently participated in a second "Liberating Structures" workshop thanks to the Obermann Center for Humanities. The techniques are meant to break mundanity and open discussions to innovation. I particularly like that the structures can be used in person and online. This flexible collaboration offers a real solution to the hybrid model I'll be using to teach this school year.
