You may be skeptical of edcamps, but you shouldn't be. They are much more engaging, and widely held than you may think. According to Kristen Swanson, Senior Educational Research Leader at BrightBytes, and co-founder of the Edcamp Movement,
"Edcamps are more than just an idea or theory; they're an international movement. The model has been replicated in 41 states and dozens of countries worldwide. Over 25,000 educators have participated in a regional Edcamp event, and many more have participated in an Edcamp-style event at their school."
Considering how grassroots edcamps are, it's going to be interesting to what happens, when the U.S. Department of Education (USDOE) holds their edcamp in June.
