I decided to give it a try - signed up for a few courses, for free : )
Using Coursera as a MOOC provider, I signed up for things that interested me and did not overlap on the calendar. You do not actually get college credit for these, but for me - I just want the knowledge. We'll see, should be interesting.
Years and years ago, before the (gulp) internet existed, while in graduate school, I did a practicum titled "Using CAI (computer assisted instruction) to Teach DOS in a Business Environment". To me, MOOCs are just another step on this path of whatever this really is. So if the CAI (implemented with 5 1/4 floppy disks!) approach was when this was in its infancy, maybe MOOCs would be like a teenager. I think it still has a ways to go, but it does seem to be picking up momentum.
One of the most interesting sites I found while googling for MOOCs is a blog titled "degree of freedom" where the author is attempting to take four years of courses in 12 months for zero dollars. It's worth a look if you are interested in MOOCs.
I'm curious if any of you have taken any MOOCs and if so, how was it?
