Push models work well when you have an established career and know what is needed to advance.<p>We&#x27;ve been stumped by Meno&#x27;s paradox since Plato&#x27;s time. I wouldn&#x27;t trust the average high-schooler&#x27;s judgement about educational choices. At that age it is far too easy to give up. Skip calculus, differential equations and the whole shebang and suddenly you&#x27;re woefully underprepared for that dream career building drones and military aircraft.<p>I certainly am happy there was some structure to my curriculum (even at the expense of a low student:teacher ratio). I was a very stupid kid - thought myself above the curriculum and all that. Were I allowed to chart my own course I would&#x27;ve been in a very bad place.
