Is it financially worth it to teach a MOOC (e.g. Coursera)?
Coursera works on a different model from Udemy. Basically, Udemy pays its instructors while Coursera does not. Coursera may split profits (or revenue) with the university, but as far as I can tell it does not pay the teaching team directly. Based on your constraints this means teaching for Coursera is not worth it. It is possible to make money teaching for Udemy. For example, in 2012 the top ten earners made 1.65 million [1] and a quarter made at least $10,000 [2].
