When I launched Class Central back in November 2011, there were around 18 or so free online courses and almost all of them were from Stanford.

There are close to 6,000 MOOCs from 600+ universities around the world

Now there are close to 6,000 MOOCs from 600+ universities around the world. This can be daunting to the millions of learners around the world who have never done an online course before.

That’s why we came up with a list of Top 50 MOOCs of All Time based on thousands of reviews written by Class Central users.

In providing a small but well-reviewed list of courses, our hope is that new learners will not be overwhelmed when entering the MOOC space. Reviews will help new learners figure out if a course is right for them, and they will have a great first experience.

So if you know someone who has never taken an online course, send them here. Use the social media buttons located on this page to share this page with your network, and to help your friends and contacts enrich their lives.

The Top 50 MOOCs will be updated regularly

The Top 50 MOOCs will be updated regularly as new courses are added and we receive new reviews. So bookmark this page for future reference.

Better yet, you can also Follow the Top 50 MOOCs on its special collection page (look for the “follow top 50” button just below the title). Followers will receive a notification whenever we update the Top 50 MOOCs list.

Oh … and if you feel that a course you took deserved to be in this list but isn’t, please find the course on Class Central and write a review for the course.

Class Central’s Top 50 MOOCs of All Time

There are a lot of usual suspects in the Top 50. Think of courses like Learning How To Learn, Harvard’s CS50x, ModPo, and Class Central’s best online course of 2015 — A Life of Happiness and Fulfillment. Courses from the founders/CEOs of edX, Coursera, and Udacity are also present.

But there are also a few surprises in the Top 50, such as a couple of language learning courses — FutureLearn’s Introduction to Dutch from the University of Groningen and Tsinghua Chinese: Start Talking with 1.3 Billion People on edX, for example.

Here is a quick summary of the Top 50 list:

Coursera is the top provider with 26 courses in the Top 50, and edX is second with 10 courses; Stanford tops the list of universities present in the Top 50 with five of their courses making it in, and MIT comes in second with three courses; the list includes courses from 34 universities, of which 21 universities are in the US; and UIUC’s Aric Rindfleisch has two courses in the top 50.

Methodology

The methodology we used for this list is simple. Using thousands of reviews written by our users, Class Central was able to sort these courses by the Bayesian average of their ratings. Then we removed all the courses with less than ten reviews (the low threshold helps smaller providers to compete on quality) and courses for which we had doubts whether they would be offered again. If a course has multiple parts, we only included the first part in the Top 50.

Note: A few of the Coursera courses in the list have a paywall for graded assignments. You can read more about it here.
