Each brain is unique. There aren't two brains ever, anywhere that are
absolutely alike. There are 30 interconnected brain centers and each
of those brain centers has it's own map. Some years ago we didn't know
the brain had 30 different centers, but now we know, but we don't really
know what goes on in each one. All we are finding out is the more we
learn, the more we know we don't know.
Then there are some weird things we are finding out, some at a gross
level. Did you know that Einstein's brain was fished out of his head
before they buried him? Because they thought it would be cool to study
his brain. Of course when Einstein died they didn't have a lot of abilities
to know what they were doing. One of the big statistics about Einstein
brain is, it wasn't bigger than anybody else's brain. They fished the
brain of a literary guy, named Balsac, they fished the brain out of
his head. His brain was 40 percent lager then Einstein. We are guessing
the size of the brain may not be all that important, or at least not
at this stage of our development.
Then it turns out that the brain can mature at different rates than
the body. Chronology there may be as much as three years difference
in brain maturation rate then there is in physical rate. In a class
of five year olds, some maybe thinking as 8 years old, and others as
2 year olds. I am not talking about special Ed, I'm talking about the
average brain. Between two normal people, you may have a huge difference
in the brain readiness to learn. Therefore holding all students of the
same age to the same standards is unfair, some brains just aren't ready
to deal with that.
Differing rates of maturity of the brain is a different thing than
the ultimate power of the brain. Your brain may be slow to get there,
but when it gets there it may be more powerful than a brain that gets
there faster. If you take a slow maturing brain, and you keep knocking
on the kid because he/she is "stupid" what you may be doing
is ultimately limiting the power of the brain to funciton, when it could
have functioned just fine or even better if we had understood this.
We have many learners on many timetables.
