Professional Development days are not very flexible. If we could use videos to flip PD, like we flip lessons for our students, teachers would have the opportunity to learn at their convenience.
Flipping PD would allow for easier differentiation. If there were a few options for which video teachers could watch, we would have more ownership of our development. We could choose the content we want to focus on and then use the actual PD day to put the knowledge into practice and collaborate with others. It would allow teachers to maximize the effectiveness of their time. The PD could also happen in person for individuals not comfortable with technology, but for tech savvy teachers, this would be a way to allow them to move at their own pace.
The presenter(s) could make the video(s) and use a platform like EdPuzzle or eduCannon to host the video. With this kind of platform, the viewer is forced to watch the whole video. Questions can be embedded to check for understanding.
