Google docs is another handy way of storing and sharing information. It is useful to be able to access the information from anywhere with an internet connection. I have found it a useful way of recieving special education information this past year.
Google Apps also has some useful tools for team planning and for the classroom. The forms could be a useful way of gathering data or giving quizzes. I like the idea of the students being able to access a set of tools to create for the classroom with only an internet connection.
