Kris Olds recently coordinated a mapping exercise with “anonymized and aggregate (i.e. non-course specific) data regarding the location of students taking courses via Coursera.” He states that “US-based platforms like Coursera and edX are serving more and more students around the world, and they will continue to do so as long as the platforms exist and partners provide courses.”
