I think that Children's exposure to School SHOULD be limited! That way they are far more likely to learn something relevant to them!Every one has their own experiences but I don't think Home Education is a good Idea. Because of home education Children's exposure to the school and society would be limited. He/She might not be confident as compared to other school going children and might end up in isolation.
As for exposure to society!!! How much exposure to society does the average school child get when incarcerated in school at least six hours a day? School is not society, it's a very artificial creation and has no resemblance to normal society outside of a school situation.
Home Educated Children are out and about in society and learning how the real world works far more often than is generally realised!
