best was "Social Psychology" by Scott Plous/Wesleyan University. inexplicably gone now from Coursera and internet afaikt
I'll offer a specific example of historical context. The University of Virginia offers an undergraduate level Coursera course on modern history.
That course's treatment of the causes and importance of the industrial revolution suggests that access to cheap energy is the key difference between an agrarian and high technology civilization. That idea and that particular history professor's connections to Washington (he was executive director of the 9/11 commission) helps to explain a forever war in the Middle East and climate change denial.
While I only just got started, there's a Cousera course named "The Modern World" that, based on the introduction, explores this topic (among others).
My technology related list includes most of the same courses already listed. But off-technology, the "modern history" class (which appears to have been split in two) was incredibly entertaining and gripping in addition to being educational.
