Why should children be not sent to school and learn on their own at home? In, this article, the author says -

Unschoolers learn just like you or I learn as adults: based on what interests them, figuring out how to learn it on their own, changing as they change, using whatever resources and learning materials they find, driven by curiosity and practical application rather than because someone says it’s important.

In last 2-3 years, I have explored stuff which has interested me, on my own – whether it is history, philosophy, world music or maths. Even when it comes to programming, I learned most of the agile related stuff – due to intrinsic motivation of wanting to know how to do deliver working software in better and efficient way.
