>"It's a very engaging way to learn and I'm getting a lot out of it. The CV course, on the other hand, has so far just been videos of the professor talking & no supplementary material. I suspect that Coursera provides the platform and leaves how the material is presented on it up to the professor."

It's probably this. I'm taking Model Thinking on Coursera and there are at least 2 pdf for each section (20 sections). Some of them from professor's book, some links on the web or some scientific articles.

I even stop reading it all because it's time consuming, but I'm happy it's been offered anyway.

About the style, well, it fits in the Content: programming stuff is better on Udacity; academical/theorical stuff, Coursera.
