I saw a link to prezi which is a program similar to PowerPoint but better and on the prezi site there were presentations of web 2.0 material. Some of it we've seen before but I thought I would share.
If you haven't heard of Sara Kajder, explore her wiki. Was her groupie for the day at the Innovative Learning Environments Conference in Hilliard - a MS/HS/Univ English teacher who is using all kinds of 21st cent skills and technologies with kids. I learned SO much!!!
