On July 28th at 10:00 am the second iteration of the best thing I have done online will begin. The Reform Symposium began as an offhand comment on Twitter, evolved into a conversation on Google Wave (remember Wave?), then turned from an idea into an event. The conference brought together a disparate group of presenters who were willing to donate their knowledge to everyone who wanted to listen. To me it represents the full potential of social media and what can happen when motivated, like-minded educators are given the tools to collaborate. I have never actually met any of my amazing collaborators, but I consider them to be my dear friends. Try to imagine organizing a global conference for educators ten years ago. Would you be able to do it with free online tools? So if you are looking for some free professional development take a look at the schedule and see if there is something you are interested in learning. Better yet, volunteer to moderate one of the sessions. Hope to see you there.
