The first thing to say this week is that these online courses are not really MOOCs, but MOTS. However, I'm going to continue to use the term MOOC for these courses as that is now established, although not technically accurate.
I struggled so badly on probability last week that I spent some time on Khan Academy. Hated it - videos poorly produced c.f. the Udacity screen captures, non-interactive (no questioning), boring, couldn't follow most of it. Having said that, I was unhappy with ST101 Unit 2: "Processes that generate data", as I felt it did not cover the title of the unit well (in contrast to Unit 1: Visualizing relationships in data, which was a very good overview of the first topic).
Back on familiar ground this week with Unit 3: normal distributions and the central limit theorem. I enjoyed the Laplace probability generations at the start of the unit though - well explained (but don't they belong in the previous Unit?). I didn't like all the complex algebra around the standard deviation - an unwelcome distraction based on the unnecessary "optional" python programming element of the course, which is increasing distracting me from the key statistics messages.
While I like the formative questions integrated with the video (which is really the strength of the Uadacity approach), it's starting to get irritating - too many itty bitty pieces. The format, which I initially liked, is starting to grate. There's also no way the bottom-end-of-Bloom's-pyramid approach translates into other disciplines with non-numercial answers.
And I'm annoyed with Udacity's mis-selling of this computer science course as a statistics course. It's not, and that's not what I signed up for. Under other circumstances, I'd be asking for my money back. For me, this is the week the cracks started to show in the Udacity model. Would I sign up for another Udactity course after this one? No, not now I've seen how their model works.
It's a bit PR-orientated and Google is clearly using it to gather user data. No change there then. Hard to complain when you're not paying. I'm now halfway through this course and it feels like a worthwhile exercise. I've picked up some really nice tips related to image searching, e.g. image search for:

Would I sign up for another course in this format, e.g. on Photoshop, Chrome or Blackboard? Yes I would, which is a very interesting contrast with Udacity.
