We devoted about a year to developing machine teaching techniques for a project. Our goal was to optimize not just the learning rate but also retention. When the subject matter is a good fit for machine teaching it can work very well. One of the problems with the human effectively limiting the rate at which the fitness function can be evaluated is that the "teaching solution" converges very slowly. This is where a-priory rules can make it more dynamic and make the difference between usable and unusable.
