I absolutely love Google Docs. I use the application for school, for work, and even for personal reasons (like co-creating a vacation itinerary with a friend). Google Docs allows for multiple users to type, edit, and converse in real time on a document. The technology also allows for cloud-based storage and sharing, as well as allows for users to access it from anywhere. Aka: Multiple students can all work on writing an assignment together regardless of spacial distance, location, or time.
For our class group project, first my group discussed via email how we would be approaching the project as a whole as well as this particular assignment. Then we utilized a Google Document in order to collaborate on writing and editing our assignment, as well as to brainstorm for the assignment and converse in general. One of the challenges, as with any group project of course, is overcoming time constraints (i.e. one person is able to work at a certain time while another is unable). Google Docs, therefore, makes it simple for everyone to contribute without the issue of time getting in the way.
