The idea of forcing everyone to march to the same beat is going to end. Personalized education and self-paced study are eventually going to win because it's better for everyone. Slower students aren't forced to "keep up" with the pack and better students aren't held back. The real questions are (1) How to standrdize evaluations to see who has learned what and to what degree they understand the material. (2) How to reallocate funds from traditionl education (teachers and classrooms) to a new model. Solve those problems and you've got something.
