Education is the only profession I know of in which a large proportion of its workers ("child-centered" progressives) are opposed to doing the very thing they are supposed to do (actively passing on knowledge and skills). There are no dentists opposed to teeth, no electricians who refuse to work with wires, no professional athletes averse to exerting themselves, no musicians who hate melody (well, actually, we may have few of those). But there is a whole segment of the teaching profession that is fundamentally against the active process of didactive instruction.
