Jenn Dorman has set up this Google site that includes a slideshare, documents and a framework for using Google tools in schools to: Create, Collaborate, Communicate and Contextualize.

It allows users to create and edit documents online while collaborating in real-time with other users, especially for trainers using it in online classroom. In addition to being a stellar way to write, store and manage your documents and slideshows, is also a fantastically useful way to create online quizzes for assessment. "
