Personally I decided to put off graduating a few more weeks to take, among other things, a human development course in child cognition because lately I've been wondering how closely the parenting books mirror what's being published in scientific journals. If I learn anything useful then I'll post it at some point in the future.
Most people seem to feel you need a good high school, but for my kids I really want to concentrate on the early years of learning. Home schooling in high school would probably be a massive improvement, but kids seem pretty happy to be with their friends then.
Anyway, I'd love to hear what you find out. I'm about 6 weeks away from being a father for the first time, so I'm very interested in the topic.
What about 1 kid though? Maybe Mom-with-a-high-school-education is only 25% as effective at teaching a 6 year old phonics as somebody with a couple years of upper division child development and educational pedagogy would be. Homeschooling can still be a win for the kid, however, because Mom can afford to spend 3-4 hours of one-on-one instruction a day. There's no way the (granted: much more effective) elementary school teacher can match that sort of investment of time.
The bad side of me wants to commit this list to memory so that I'll be prepared the next time I see her. :-)
