My wife had her VERY first black student this last year for 3rd grade (She's taught 100's of hispanics, but never a blac). She started off saying.. he was charming, and had potential, but wasn't focused.... by the end of the year, she hated him and confesed that he was the worst student she EVER had. He would brutally and violently bully the other Mexican students, he even attempted to rape one of the other students. He COULD NOT sit still, and would humm and talk to himself during testing. He would ignore the most basic commands, such as sit down, or write down your name. He was as teachable as a chimpanzee (My words, not hers)
