I have tried to use google docs before, actually I was playing around on it trying to find things I could use at work. Its a great tool to use, especially for groups or people working on a project. What I noticed I like about google docs immediately is EVERYONE can use it. Last year I put Word 2007 on my computer and when I would forward things to other colleagues they were unable to open because they had Word 2003. Lastly, all of these docs are saved online, so you don't have to worry about your computer crashing and you losing it.
I wish more Physical Education teachers would use this, create and publish written work they will use with their classes. Then we as educators would have use of a bank of ideas and already completed work we would only have to rework a little for our own use. Below is the link to the written assignment I am working on to give to students who having missing work.
