"First came cloud-based word processing in the form of Google Docs.
With cloud-based word processing in education, teachers could remotely access student work, students (provided they had internet access and had a Google account) could retrieve their work from anywhere, and writers could collaborate in real-time with their peers to double-team the pain-staking work that is the writing process.
Then Google finally delivered on the long-rumored Google Drive, giving teachers and students the ability to store both documents and images, pdfs and presentations, video files, and more, turning Google into a cloud hard-drive of sorts. Further, the change to Google Drive brought with it access to apps to bolster what Google Drive could do.
Which brings us to the latest–and perhaps best–evolution of Google Drive for teachers."
