Teacher Dashboard is a tool for teachers who use Microsoft Office 365 in the classroom. This presentation uses SWAY (another new product) to show off the different features.
Looking through this, the dashboard seems very similar to Google Classrooms but with the added feature of management of One Drive folders. Of course the big sticking point for both these products is the lack of an MIS to manage the groups and the work is pretty much down to you!
Looking further afield there are some VLEs that offer links from Office365. I wonder if there might be a way to incorporate Dashboard here?
