"A good teacher can inspire hope, ignite the imagination, and instill a love of learning."
At its core, Edcamp is a ground up professional day of learning that is often referred to as an unconference. There are no formal presentations, keynotes, etc. I had the opportunity to participate in a mini-edcamp with Kristen Swanson, the chair of the Edcamp Foundation and it was incredible. If you're intrinsically motivated to learn and develop as a professional this model is for you.
Typically, the schedule is built live based on the items participants are knowledgeable about and what they want to know more about. This can be done using a physical board, or in the case of the Edcamp I attended, using Google Docs. For the sessions I attended, we moved to a physical space and navigated on our wireless devices to a cloud-based note-taking page that was shared with everyone else in the session and also linked back to the schedule. The sessions were driven by discussions between professionals seeking to learn from one another and improve their practice. The discussions were thought provoking, informative and participation was encouraged. By the end of the final sessions, the notes from all sessions were accessible via the online schedule. We then had a "smackdown" in the larger group in which people had a minute or less to speak about something that really works for them. It was an incredible experience and I learned a lot. The video below is from a different Edcamp, but I think you'll see why they are so powerful.
