I found the opening video funny though I do want to warn you that it includes a conversation about peeing in one’s pants in case you are in a room full of students taking a test or something at the moment. While this site certainly was not designed exclusively for the academic world, there are definitely ways to use its features in a classroom setting.
For example, here is a clip I made with a picture and information about Susan B. Anthony (the opposite extreme from the intro. video; I went serious) ~ it took only a few minutes to create:If you don't have a place to embed your video, that is okay. Blabberize will give you a link to share with everyone. You can see the above one here.
What a fun way to make a famous person in history share information about his or her self, or to have a character in a book talk about the conflict in his or her life, or to give a small group of students at a station directions on an assignment while you are working with other students.
Here is a link to a blog entry about Blabberize that describes several ways to use it in an academic setting: http://blog.learningtoday.com/blog/bid/27337/Blab-On-Interactive-Classroom-Tool?source=Blog_Email_[Blab+On!+–+Interacti]Have fun! Happy New Year!
