Next week I'm teaching a two-part online workshop that includes a Webinar, Action Learning Exercise, and A Reflection Discussiona for Extension professionals and how they can begin to use tagging for collaboration and knowledge shraing.
I decided to use the Ethan Zuckerman advice of point don't write -- and pointed to some excellent screencasts and videos about social bookmarking. I'm thinking about doing a remix though because there is redundancy and also because I just discovered a way to download youtube videos and convert them so I can remix.
The presentation wiki and resources can be found here.
The reflection exercise can be found here.
