the defining spirit or mood of a particular period of history as shown by the ideas and beliefs of the time.
2015 was a big year for Class Central. Class Central launched as a side project in November 2011. It’s more than four years old now, and it’s almost as old as the modern MOOC movement, which began with three courses from Stanford in October 2011. And, as with MOOCs, more people have used Class Central in 2015 than in the previous three years combined. Close to two million students used Class Central in 2015 to help them decide which online course they wanted to take next.
These students wrote more than 7,000 reviews, added courses 200,000 times to MOOC Tracker, and ran 250,000 searches. Those numbers are just from 2015, and these activities provide a strong and unique data set which captures a student’s intent. Like Google, we have decided to release a zeitgeist and give our readers (that’s you!) a sense of what students around the world are looking at.
These students wrote 7k+ reviews, added courses 200k+ times to MOOC Tracker, and ran 250k+ searches.
Class Central is primarily a discovery platform — students prefer to browse rather than search. Our Subjects page (built using an online course taxonomy, which we open-sourced earlier this year enables) a student to browse courses based on their interests.
Only 6% of students end up using the search functionality, but between them those students still ran over 250,000 searches using 60,000 search terms. The top 25 search keywords are below. These account for 13% of all searches.

We’ve ranked universities the same way that we’d ranked courses, and we came up with some interesting results.
We used the course ratings of a course to represent their university, and then we took a bayesian average. We filtered out universities with less than 5 courses or 10 ratings.
1. Santa Fe Institute
2. Monash University
3. Case Western Reserve University
4. San Jose State University
5. Australian National University
6. Yale University
7. The University of North Carolina at Chapel Hill
8. University of Melbourne
9. University of Queensland
10. Wharton School of the University of Pennsylvania
This list looks very different compared to the Best Global Universities Rankings that U.S. News publishes every year. Four universities in Class Central’s list are from Australia! It has a long way to go, but online education has the potential to enable lesser-known universities from around the world to compete on an equal footing with top tier universities.
