Strange, the first available video says it's from 2012.

This class, and many of Erik Demaine's other classes, are taught in a "reverse lecture" style, where the lecture videos are recorded once and released online, the students watch the videos beforehand, and then come to the classroom to solve (often open) research problems collaboratively.

I believe the video you were looking at was recorded during the 2010 instance of the class, and then released in 2012 for the next iteration of it.

We called that flipped-classroom in my university and it appears to be pretty common when the university has high performing students.

My high school had a whole push for teachers to try flipped classes. I found them to be really nice, skipping through the video when they're repeating something I already got, or re-watching something if it didn't make sense. Despite this, general sentiment of my school seemed to be that they were terrible. I heard complaints such as not being able to ask questions immediately, or feeling disengaged compared to being taught live.

All and all I wish my college did them, I struggle to sit through lectures.

From course homepage:

> Most course material is covered in video lectures recorded in 2010 (already watched by over 350,000 people), which you can conveniently play at faster speed than real time. There may also be some new material presented by the professor and/or guest lecturers, which will be recorded for asynchronous viewing.

They may have meant "2010s"?
