This electric conference was an outstanding example of a what can be accomplished with the help of one's Personal Learning Network. The entire conference took place via Elluminate sessions which have been archived. Podcasts are being made available as well.
My favorite was the keynote by Shelly Blake-Plock. He gave many examples of practical and everyday uses of online tools such as Twitter, wikis, blogs, and more. How his classroom was converted to function as a 21st century classroom is amazing!
Two others that I enjoyed and recommend are Richard Byrne's Back-Channeling in the Classroom and Joe Bower's Abolishing and Replacing Grading.
The links for the archived Elluminate sessions are found on the ABOUT tab, MEET THE PRESENTERS. Each presenter has a separate page with information and a description of their presentation with links to their website, Twitter handle, and the archived Elluminate session.
A Google doc, Links-Reform Symposium 2010 , was collectively created to gather links discussed by the presenters or shared in the chat by the participants into one great resource.
