Here is another tutorial for teachers and students using Schoology and Google Drive. When teachers create an assignment, students can turn in Google Drive documents very easily. Watch the video that includes all steps.

But, why use Schoology if we already have Teacher Dashboard?

I believe they serve very different purposes. Teacher Dashboard allows teachers to view student work while it is in progress. Students need scaffolding as they work on lengthy assignments, and Teacher Dashboard and Google Drive provide the perfect combination for this. Using the commenting function and the revision history function, teachers can track student progress and give constructive feedback. Once the due date arrives, Schoology allows teachers to collect an assignment that will not be edited further.
