> Look at the MOOC experiments where the percentage of people who pass is in the single digits. (There are all kinds of arguments that some people only sign up for part of the course anyway, that people can take it three times at much less cost than the traditional way once, etc., but single digits is a shock.) Could you elaborate on this? I've done a couple of MOOCs recently (Coursera in conjuction with Columbia, Princeton, etc). I could see that tens of thousands of others had enrolled. I'm curious about what the completion rate is. I personally got some value out of them. I'm wondering why they might be considered failures. In fact I'm seeing lots more courses come up.
