My husband and I don't have kids and were talking about this a few weeks ago. It's utterly ridiculous. Why doesn't the government just take your kids away as soon as you have them and raise them itself? Oh, wait, Communist governments have been known to do that. Never popular, even among communists.
Why does it seem that only homeschooled kids win the national spelling bee, year after year? I seem to recall that they usually take the geography bees as well. Maybe it's because they focus on one thing to the exclusion of other subjects, but is that a bad thing? Look at all the time I wasted in school learning to graph algebra equations. What good is that to anyone? Sure, solving for X in a simple equation can come in handy in real life sometimes, but why do I care to see a visual representation of all possible answers of a two-variable equation? It was an even bigger waste of time when you consider I ended up a history major. And yes, my love of history manifested very early on. So if a kid likes spelling, English or foreign languages is probably where he will be happiest. Geography kids might do best in sociology or political science. What's wrong with playing to a kid's interests early on and just teaching them the basics of everything else? Is my life truly enriched because I could once balance a chemical equation? I sure can't do that anymore. But I remember a lot of what I learned in high school history class.
Or it could just come down to the fact that a one-on-one teacher can do better than a 1 to 30 teacher, regardless of credentials. Some homeschool parents I know of take field trips everywhere and expose their kids to a lot more than your public school (or even private school) kid is exposed to. We have a friend who does medieval re-enacting with us and she's managed the last couple of years to get her gifted daughter out of school for a week and bring her to our big reenactment. She spends the week taking kids' classes and doing activities with her mom, like drawing and painting. She goes back to school afterwards and blows everyone out of the water by talking about her medieval name and how she researched it for historical accuracy, she has her own arms and can describe the heraldic elements in them, and she shows them the weaving and spinning and cord-braiding she learned to do.
My husband was cooking dinner over a fire at an 18th century reenactment once and got the following questions: Is that a real chicken? Is that a real fire?
There's public education for you. People can't even regonize the smell of a cooking chicken, nor tell when a fire is real. Apparently some people don't even know that you CAN cook food over a fire. That's the sort of intelligence you breed when kids don't learn anything but how to fill in bubbles with a #2 pencil. Like life is made up of multiple-choice answers that you have a 25% chance of getting right at random.
Kids who are exclusively homeschooled can always take the SAT and ACT to get scores that colleges can understand. But some colleges like homeschool students. There's one in California that I read about that has almost no structure to it. You are basically doing independent study the entire time, with a teacher there just to help guide you in your research. They take in a lot of homeschool kids because homeschool kids are already used to that kind of educational freedom, have already been encouraged to learn things for themselves. Some people complain that they don't learn to work in the structure of the corporate world, but I say, why do they need to? They have the discipline and free-thinking and creative abilities to be in business for themselves. They're the sort of people who go on to invent wonderful new things. Einstein did his best thinking out of college. I seem to recall that Bill Gates didn't fair very well in college either. Sometimes structure is more of a hinderance than a help.
Remember, in a public school, kids are taught only what the slower half of the kids can learn. The brighter kids are bored while the kids who are the slowest to learn something are left behind. Homeschooling corrects for both. You can go as far and as fast as your kid can, or you can slow down and do whatever is needed to get over the tough stuff. My ex-roommate had learing problems with math that her teachers didn't care to help her with, and it got to the point that she just shut down in math class and failed. Her mother took her out of school and said they didn't crack a math book for 6 months. They worked on only what was easiest for her until she was doing really well, then her mom reintroduced math and slowly worked her up. But for a while she was doing things like English and history at a higher grade level (than her age would call for), but doing math at a lower grade level. She eventually had the problem corrected enough she could put her back in a private school at the proper grade level for her age. But what would have happened if her mother hadn't intervened? Her mother who didn't have a teacher's certificate (did have a college degree), yet who fixed a problem teachers didn't/couldn't.
