TeacherTube, the latest service joining the Web 2.0 education boom, is burning up the edu 'sphere with rave reviews. As the name suggests, this new service is YouTube for teachers. TeacherTube also has community features via TeacherTube groups. I think this is a brilliant idea, and frankly, one that educators have been wanting for a long time.
However, moving forward, I think it will be interesting to see how well TeacherTube is able to scale and keeping up with growth. They will also face the same challenges that all other educational providers have in terms of site blocking by school administrators, user abuse, as well as the 100 pound copyright gorilla.
The TeacherTube community has created, uploaded and shared a lot of great content. For example, you can find anything from (via site or tag search) professional development tutorials on PBWiki, to a Google Earth Tour of the life of Anne Frank and her family.
Another great feature is the ability to attach support materials (handouts, worksheets, teacher notes) right on the same page as the video for other teachers to use.
TeacherTube also "plays nice" with other forms of social media by providing you with a link and/or HTML snippet so you can easily embed a TeacherTube video directly into your class website, wiki, or blog.
