EdCamp is a grassroots movement of do-it-yourself professional development "un-conferences" that originated in Philadelphia in November 2010. In just a little over a year and a half the phenomenon has gained serious momentum across the country and now around the globe. This teacher-driven, bottom-up approach to professional development has reinvigorated educators' passions for learning by creating an environment that, according to participants, rewards their curiosity, allows them to explore their passions, and values their knowledge and experience in the classroom. In this interview, four EdCamp participants--Kristen Swanson, Dan Callahan, Bill Selak, and Karen Blumberg--talk about how social media and web 2.0 tools have fanned the flames of this movement and why teachers are so eager for a professional development experience that they themselves create.
