If unschooling can't work in the real world, nothing at all can. People will say "How will they learn algebra in the real world?" Is there algebra in the real world? If not, why should it be learned? If so, why should it be separated artificially from its actual uses? "Why?" should always be the question that comes before "What?" and "How?" There is a Sesame Street book called Grover and the Everything in the Whole Wide World Museum. There is a "things under the sea" room and "things in the sky" room, but still each room is just a room in a museum, no windows, everything out of context. Then he opens a big door marked "Everything Else" and goes out into the sunshine. There is unschooling.
