This is the most useful collaboration tool that I have created so far in my career. At East Lee Campus, we have eight teachers, one computer lab and one cart of netbooks. Scheduling was a nightmare when we tried it on a sheet of calendar paper hung on the computer lab door. The paper did not allow us to make last minute changes or check availability from our classroom. Plus, it was kinda mean to make the teachers whose classrooms were in the portables to walk across the parking lot in all sorts of weather to schedule class uses. I used a template I found on Google Docs for a basic calendar. On each date, if you want to use the computers, you enter your name, the hour you want them and CL for computer lab or NB for netbooks. We run on a first-come, first-serve model, but we have been known to negotiate trades when needed. It also makes it much easier to mediate teacher time conflicts. The person whose name is on the document gets the resources....although trades, swaps and time-shares have been known to happen.
