Google docs

I know that google docs is not a new thing to most people, but it is new to me. I've been playing with all the different things that google has: like presentations, sites, etc; and google docs has stood out to me this past week. I think this can be a really good collaborative tool that students can use when studying for tests. All that needs to happen is someone (student or teacher) needs to put the study guide on a google doc, and everyone can fill in the answers collaboratively. This is a good thing to use if a student has missed a day or just doesn't understand a concept. It is a good way for peers to help one another out for studying for tests.
