The school where I work has a been a Google Apps for Education school for many years. The teachers who do use it regularly know that the collaboration features can bolster student learning and provide teachers with valuable formative assessment data, but constantly sharing files can become cumbersome. I conducted some research and found a few easy strategies to facilitate sharing of files within a classroom that will help to maintain organization within Google Drive. I hope that this will help to encourage more teachers to put Google Drive to use with their students.
