The analytics beta is great for a getting a quick look at general student status. It would be even more helpful if there was navigation to investigate further throughout.
- click on an assignment and have the option to open in speedgrader.
- click on a student name and open their grades to see breakdown and not just average.
I would add last teacher interaction to the dashboard as well, so that teachers and supervisors and get a quick look and make sure communication is running smoothly.
