This is late notice, but I want to put it out there anyway. Tomorrow (June 10) at 3pm EST, Steven Katz and Simple K12 are presenting a free webinar about teaching with video. Steven is the author of Teach With Video, a practical guide to integrate video projects into the subjects you teach. Register for the webinar here.
