In order to do that, we would have to be able to measure “learning”, and so far, we have only been able to measure “ability to regurgitate facts”. It does not help that the mainstream educational paradigm is “to fill the blank slate that is the student”.

See: John Taylor Gatto’s book on this subject— The Underground History of American Education.

There are other educational paradigms, but they are radically different — no tests, no curriculum, no “fill the blank slate”, no measuring.
