Google Docs and Forms are a neat tool. I am not sure how docs can be used in my choir classroom because there is never really a situation where we will need to live edit a document. However, it is very interesting and something I may use in my personal life.
Google forms is something that I could possibly use with my students with regard to business such as choir trips, auditions, payments, and things of that nature. It's a good way for them to keep track of things and stay organized with what they need to do.
