It was not the fact that they were black. It was the fact that, as a black student, I was not subject to the same warped expectations that I found common while taking higher-level courses under some of my white teachers. Not every white teacher was like this; however, I did notice, particularly in my AP courses, that many were less supportive and understanding of black students who hit periods of difficulty, and more disciplinarian in their regard. I'm unconvinced that American pedagogy in general has shaken off the inclination to view students of color as un-growing children to be trained and tamed, rather than growing thinkers to be taught and empowered.
