One additional point about the Circuits and Electronics course stats I cited yesterday. Most of the talk about MOOC-scale has been about the number of sign-ups.
But that’s the wrong end of the problem. What we care about is cost per completion. And at 7,000 completers, there’s certainly some scale to this course but it’s not quite the scale we think of when we are looking at “marginal cost of zero” sorts of solutions.
That may sound nitpicky, but it’s not. Back in the late 90s/early aughts I had the honor of working on some of the best online learning ever produced, at Roger Schank’s company Cognitive Arts. And we would spend a million a course because of this marginal cost of zero idea. If each additional enrollment costs no more money, you can afford to build elearning that is designed at the level we normally see in videogames. And I don’t just mean in terms of flash — when you put a million dollars into an online course, every piece of that course is carefully designed to have the maximum impact.
But you have to have scale to do that. At a million dollars a course, for 7,000 students it’s costing you about $150 a completer. That’s a deal for society, but it’s not the deal Silicon Valley interested in. If Silicon Valley is ever going to take completion seriously (which they may not, since an eyeball is an eyeball is an eyeball) then the cost per completion is going to have to get a lot lower than that. And my guess is the way they will do that is not by making classes better, but by keeping the cost per class pretty low.
What this means, unfortunately, is the marginal cost of zero thing might be a lie we are telling ourselves. Someone somewhere recently said “You promised us jetpacks and all we got were these lousy video lectures” (was it Audrey?). I’m saying that if there really was a marginal cost of zero, or if the players involved even believed they were paying a marginal cost of zero game, we would have jetpacks, not these substandard courses. The fact we don’t either indicates the market is not there yet or that, maybe, the market is not heading there at all. I hope Let’s hope it’s the former case and not the latter.

Needed to draft you a tiny word so as to thank you very much yet again on the awesome thoughts you have shown on this website. This has been shockingly generous of people like you to grant unhampered just what a few people could have offered for sale as an electronic book to generate some money for themselves, especially now that you might have tried it in the event you decided. These good tips in addition worked like the great way to recognize that other individuals have similar dreams like my own to find out good deal more related to this problem. I know there are a lot more pleasant instances in the future for people who scan through your blog post.
