This was a great webinar about using Skype in the classroom. Classroom 2.0 Live is now creating a Livebinder for each presentation. (They are at noon on Saturdays.)
Recording in several different formats and great livebinder from 4-1-17 Classroom 2.0 Weimar with Marialice Currant and her son. it was truly a worldwide audience
Great session by Hella Rumschlag and Laurie Loughery of Mohawk Trails Elementary. Their project involved collaborating with schools across the country using various web 2.0 tools
Simple K-12 periodically offers some free webinars on web 2.0 topics (of course, trying to entice people to become subscribers), but even the free ones include some great presenters and topics
Archive of a great webinar from 12-10-11 dealing with Livescribe/Smartpens. The webinar included primary, secondary, and college educators who gave many examples. The livebinder that accompanies this is filled with resources and examples.
These are wonderful, free webinars. Generally, they are every Saturday at noon, and they include teachers who are using various technology tools. The moderators are great, and Elluminate is my favorite platform for webinars. The links are all collected (now in livebinder), and the archive is even available in iTunes as an mp4 or mp3 (some people listen weekly on their iPods).
