That is an example of "actively changing students", rather then "passing information". It is of course much more effective, but it is also more expensive. It requires better teachers and intimate knowledge of the students in regard to what you are about to teach. Unfortunately education (public or private) is still a Second Wave enterprise, made for scale and not performance. After all, you're not talking about teaching a class of kids, but all the kids in a country. And that is still not feasible with anything else then "passing information".
