Well - yes I can see the need for specialised training when dealing with a lot of kids with a diversity of abilities, disabilities, cognitive levels, etc. And faced with a roomful (30+ kids) - yeah that's a challenge.
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.
I don't doubt it. I think anyone on this list could probably learn enough about reading programs and development psyche to teach their kids quite well. It's just that its nothing to do with being able to read yourself.
