The 2008 K-12 Online Conference is a free, international, online event for educators around the globe. The purpose of the conference is to advance the use of leading-edge educational technologies (specifically web 2.0 tools) in the cause of high-quality K-12 teaching and learning, worldwide. The conference, and related information, is located at: http://k12onlineconference.org. A panel of distinguished technology educators from the U.S. and several other nations select presenters via a blind review process. All conference staff and presenters volunteer their time free of charge. This year (as in 2006 and 2007) 41 presentations will be published online asynchronously from October 13-31, 2008. Most are multi-media lectures or screencasts available in both iPod-compatible video podcast and audio mp3 versions. The 2007 K-12 Online Conference drew more than 100,000 attendees. Primary presentation files are archived indefinitely by the College of William and Mary. Published presentations include links to supplementary materials. Learn more on www.k12onlineconference.org.
