Please read the whole post at the link above but here is portion of it:
“Unschooling is only part of the equation though. A trip to the grocery store is an obvious venture to teach a child to count money. But what experiences will teach differential equations, quantum chemistry, palaeopathology, or combinatorial optimization? Eventually, experiences won’t be enough and you’ll need to find other supplemental means of learning. This is where autodidactism comes in.
Autodidacts are people who teach themselves whatever grabs their interest.”
I find that our family falls into this area of learning… unschooling with the encouragement to be autodidactic.
