A host of sessions from this year's NECC 2008 conference are going to be live streamed via Mogolus, UStream.tv and other tools. If you can't make this year's conference (or if you want to double up on your learning while in San Antonio) plan to tune into these sessions.
The wiki for the Flatclassroom Summit held this year in Mumbai, India. Check this out. Follow the links to the ustream archives and listen to the reflections of the participating teachers. You don't have to go to Mumbai to have your own flatclassroom project. As Thomas Friedman says, "If it's not happening, it's because you're not doing it."
