I appreciated being exposed to the EdCamp/unconference concept.  In Diving into Inquiry (https://www.trevormackenzie.com/dive-into-inquiry), Trevor Mackenzie talks about the first few days of his class being devoted to developing the curriculum for the year.  I wonder if doing this through the structure of an EdCamp would work.  I would be interested in seeing how it would be possible to borrow some of the key components ( https://www.edutopia.org/blog/edcamp-is-future-of-pd-mary-beth-hertz) and things that people have found work well in in EdCamps (https://www.edsurge.com/news/2018-04-10-5-tips-for-planning-a-kidcamp-the-student-driven-edcamp) in order to try it out.
