If you want to see a playback of your Google Doc writing and revisions in an easy to view format, give the extension Draftback a test drive. Draftback allows you to play back everything you’ve written in a Google Doc and view it as a movie. With a Google Doc, the revision history tracks every keystroke and the history is available to anyone you give “Edit” permissions to. As a teacher, you can easily play back and analyze the process a student used on a piece of writing.
Draftback can be found in the Chrome Web Store in Extensions. Unlike other extensions, this one appears in the document on the upper right-hand corner.
After selecting the Draftback button you can see a playback of your writing that looks similar to this:
Document data and a stats summary are also available and can be found in the document graphs and statistics link. Once Draftback is installed, it will work in any Google Doc no matter when it was created. Draftback is great way to peer over the shoulders of your students to understand all the writing and rewriting they’ve done on an assignment.
