This looks interesting/unmissable:
“The K-12 Online Conference invites participation from educators around the world interested in innovative ways Web 2.0 tools and technologies can be used to improve learning.
“This FREE conference is run by volunteers and open to everyone. The 2008 conference theme is Amplifying Possibilities. This year’s conference begins with a pre-conference keynote the week of October 13, 2008. The following two weeks, October 20-24 and October 27-31, forty presentations will be posted online to the conference blog for participants to download and view. Live Events in the form of three Fireside Chats and a culminating When Night Falls event will be announced.
“Everyone is encouraged to participate in both live events during the conference as well as asynchronous conversations.
