My gf worked for Coursera for a while so I tried some of their courses. The big win for me was that every one I tried included a full transcript. So my use model was to simply read the transcripts and if I didn't understand something I clicked on the text which would jump to that point in the video.

But in general for the stuff I want to learn I prefer to read a book, which is harder to find for really recent stuff like this.
