online education

Online classes are better subject to forces of competition (no one is required to take them, and there are more options both within and between subjects.) Therefore the following forces operate:

For a given quality/rigor of curriculum, improving teaching methods will increase the number of people who want to take an online class.

For a given curriculum, lowering the rigor will increase the number of people who want to take an online class.

The former effect is limited: no matter how good the teaching is, work is required to understand and master complex subjects.

The latter may also be limited: reducing rigor loses a few people at the top end who want a very thorough understanding of a subject and picks up a lot more (because the distribution is skewed) on the lower end who want a simple introduction. But, at some point even the lower end isn't tempted by a class that can be completed by 7 year olds.

I think that on the current margin, the latter is more effective at increasing audience. At least, it seems to be the tactic overtly chosen by many classes.

Loosely speaking, the former effect is welfare-improving, while the latter is welfare-reducing, but both are potential avenues for an online course offerer whose objective is to maximize its audience. (At this point in time, at the dawn of online education, I think that is indeed the main objective.)

How do we set up the system so that the former is the more tempting option?
