A new tool called Insights is available to instructors from the Instructor panel of their live course:
The tool contains graphs and data on student enrollment and engagement. You will start on the Enrollment page, where you can switch between Activity and Geography views from the menu on the top left. You can also switch to the Engagement page, which contains data on how students are interacting with course content.
Some of the data is downloadable as a CSV file. If you have trouble opening the file, make sure your system preferences allow you to open files from unidentified developers. For details on how to change this setting, check here.
