I don't need to know how children learn.
I know my 4 year old knows how to spell her name, her sisters name, her mothers name, my name, her address, her phone number, can spell every state on the map, can do basic addition and subtraction.... and on.
And I used the same principles to 'teach' her as I have used to teach adults one of the most complex manufacturing machines in the world.
In the end, I am not too concerned about studies. I am concerned about my daughters being better than me. And I am concerned with my co-workers being self sustaining.
And it all comes down to the very same thing. Attention span. Ever wonder why a kid can rattle off just about every sports stat known to man but he can't do his algebra? Or he can recall every known species of dinosaur to walk the earth, yet can't read a sentence?
I'll stay the Monday morning Quarterback. You can rely on your studies.
