'Unschooling' is an educational method/philosophy.

Rather than the conventional approach of defined courses / curricula, it encourages exploration of activities initiated by the children themselves, and learning through natural life experiences.

For example as a result of something the child experiences, the child may have a sudden interest in Greek Mythology, which would then be explored at that point.

While its certainly a form of home education, it is only a subset of homeschoolers that follow this method; many (most?) homeschoolers continue to follow structured curricula similar to conventional schooling.
