So the recent release of HarvardX and MITX data on MOOCs is exciting. The data is scrubbed to protect the privacy of the students who took the courses, but still yields a wealth of interesting stuff. But you must interact.
This dashboard starts with the intro, but has five views you can see by clicking across the tabs at the top. Once on a view, you can limit the data shown by (depending on the dashboard), by gender, education levels of students, home country, or institution, and whether the student registered or completed the course for a grade. Data are shown by course, age, home country, and institution.
Have fun, and let me know what jumps out at you.
