Absolutely! (And Vatech was exactly on-topic--he answered the question in this thread title.)
Now I'm gonna get slightly off-topic in response to the direction this thread has taken:
Has anyone ever seen footage from the original "Blue eye/ Brown Eye Experiment"? It was staggering to see.
After ML King was assassinated, this teacher in the Midwest wanted to understand racism. She came in one day and announced to her class (2nd graders or something close): "Blue eyed kids are dumber than the rest. It's an absolute fact."
She treated them as such all day--rearranged the seats so they were in the back, monitored them on the playground (they're a combative bunch, too--never play with others those blue-eyes).
Sure enough, the blue-eyed kids couldn't do math problems they knew the day previous. Their reading suffered. Fights broke out among them.
Next day, the teacher says: "I was mistaken, it's the brown eyes who are stupid." And sure enough, the drama was repeated.
I tried to bring up the difference in EDUCATION and how profoundly that affects things--how it makes the concepts of a level playing field and "equal opportunity" kind of moot. You start off as kids and have messages reinforced every day....
All the teachers in my area vie to teach in the rich areas. A teacher's dream! Well-behaved kids on Preparation H (as in "Harvard"). No one wants the poor, urban schools. And it is color-coded, believe me.
