My PRIVATE thoughts on home schooling is that it is an extremely bad idea. Kids need to come together into a context where they can learn together. Sure, schools are government (or religous centers’) tools but you do not only learn in class, you learn on the breaks when you socialize with other kids and you learn other valuable lessons – not only those being printed into a book. Of course parents should devote more time to their kids and share their knowledge, but I also the kids in our world deserve profesionals on the field that are educated for what they are doing. I also believe it is a bad idea because there is a great risk of that the kids will be social outcasts due to that they do not participate within the “normal” child community.
POLITICALLY I think of course that home schooling ought to be legal. If some families choose to home school their kids it shouldn’t be any of my concernes, neither for the politicians who run your country.
To sum it up, home schooling should exist and should neither be supported nor bashed down by governments. It’s simply none of their concern. However, I would never do it to my own kids.
