Daphne Koller of Coursera gives a very intriguing TedTalk. She even throws out some good data. The machine learning class would have to be taught on-campus for 250 years to reach the same amount of students enrolled in the online class last fall. Here are some other impressive numbers.
- 640,000 students
- 190 countries
- 1.5 million enrollments
- 6 million quizzes
- 14 million videos viewed
Those are some impressive numbers. Daphne also provided the following quote.
In many of our [online] courses, the median response time for a question on the question and answer forum was 22 minutes — which is not a level of service I have ever offered to my Stanford students.
