My kids are homeschooled, and they tell me they estimate that 40% of DIYers are homeschooled. Ok, so they are kids, and that may be an exaggeration, but I would believe that they are correct in thinking that the percentage of homeschooled students on DIY is much higher than in the general population.
It's relevant to your question is that a lot of us homeschooling parents (and other parents too!) approach education with the view that after we teach them how to read, write, and do basic math - it's not about us teaching them, but them teaching themselves. Once they have those basic skills, we try to slip more in the role of mentor, resource-provider, and constructive critic. The kids very naturally adapt to this kind of learning (as I believe this kind of learning is very natural to human beings, if permitted), but very quickly into the game they realize that their peers are not taking the same approach. School and society has beaten away that approach, and has taught them that in order to do or learn anything new, they must be taught by an adult.
DIY is like a whole community of kids (whether homeschooled or not) that DO think they can do and learn new things on their own. And that's an amazing thing for them to experience. What it has done for me is lifted some of the burden of trying to convince them that doing stuff on their own ISN'T weird. That they ARE capable of doing a lot more than they think. I hear a lot less of "Well, nobody ELSE I know is expected to do this all by themselves", and I am convinced DIY has played a role in that. Because now, there are all these DIYers inspiring them. Well shoot, now they DO know kids who are doing X on their own. And MORE than X on their own. I saw pictures!
I'm getting less of "Can you teach me how to..." and more of "Look what I figured out how to do!"
So yay for that!
