Unfortunately, in many schools, when black kids do well, their peers put them down for being too white.
Think back to Jamie Escalante teaching Mexican kids calculus at Garfield High in inner city Los Angeles (made into the movie, Stand and Deliver). According to wikipedia, " In 1987, 27% of all Mexican Americans who scored 3 or higher on the calculus AP exam were students at Garfield High." Why doesn't this professor implement programs for (a) seeing that education is valued in the home, (b) changing the perspective of those black kids who think doing well in school is a bad thing, and (c) setting expectations higher, not lower. This crazy professor is setting up kids to fail.
