How many white elementary school students are taught by black teachers who can’t do basic math no less teach it...
I had a few black teachers in elementary school. One explained gravity as being a layer of material on the surface of the earth. And the reason a wheel rolls is that its shape successfully pushes the gravity out of the way.
...or teachers who can't even speak proper English..
IMO, any teacher who uses "Ebonics" -- in any classroom other than a graduate-level "Linguistics" class -- should be fired summarily, and blackballed from all institutions of learning.
