For many teachers, the phrase professional development conjures up mandatory, snooze-inducing, school-sponsored lectures.
EdCamp, an "unconference" for educators that was conceived in the Philadelphia region last year, was designed to be the exact opposite: the free events are participant-driven and attendance is strictly voluntary.
There are no keynote speakers or even set schedules. Instead, attendees sign up the morning of an EdCamp - often on Post-it notes or index cards - to lead discussions on whatever they are most interested in talking or hearing about.
The first EdCamp, held last May in Philadelphia, has spawned a national movement. About 16 other EdCamps have followed from California to Florida, including a second Philadelphia event held recently at the Wharton School at the University of Pennsylvania, and at least eight more scheduled for later this year.
