Don't think I've ever read a stronger review of a book. I bought it and read it and whole heartedly agree. Don't launch your wtg wkshp without this book!
Glogster is an online FREE interactive poster tool. Ability to add hyperlinked video, insert digital images and voice (mp3)--lots of ways to personalize. Great potential (e.g., introduce self in course, individual book reports, group projects). EASY to use.
I just found this this week!! I love it. I think I might use it for our WWII unit, or disUtopian book reports, or as a culminating activity for my postcards from the past/postcard to the future workshop! So many uses!!
