Here is a great video that explains what a “wiki” is in a clever way.  Wikis enable a group of people to write, edit, and produce one single document (you can even print it!).  What’s great is that it also allows you to see a history of all the editing.  This has MANY applications in the classroom as students can use it to collaborate on a single written piece.  You as the teacher can not only have a clean copy of the document, but you can access the history and find out WHO edited and contributed what pieces! 

Let us know if you want to help use this in your classroom.  You can get started by going to Wikispaces.  It’s free!
