One of the more interesting trends of these discussions is that we all claim to be be "flipped" history teachers but we all have a different way of implementing it. I think it speaks to the truth that the flipped classroom is a mindset, not a strict list of rules. I think most of us started with Flipped 101 and then it evolved into the various ways we help the students take more ownership in their education. I think it develops differently for each of us based on our personalities and the students we serve.
Below you'll can check out some of the Hangouts I have been a part of.
