Modern public-education history is littered with novel education theories that have failed so spectacularly that the terms are now used as pejoratives. For instance, when I was in elementary school in the 1960s, the “New Math” focused on teaching abstractions rather than fundamentals. You can find reams of research documenting its failure decades later, but the evidence was recognized almost immediately.
It’s easier to indoctrinate uneducated children.
