I know families who are homeschooling their kids. In these families the mother was already at home and for whatever reason, starting very early the decision was made not to send the kids on to traditional schools. These families follow curriculums put out by publishing companies. For high school they are thinking of supplementing with online courses. This is still not unschooling which goes a step further.
Does your family or people you know follow non traditional learning approaches? How has that worked out?
