According to Education Week, “Students feel happier, more valued, and more motivated when they have a teacher of the same race and gender as them, a new study finds.” And, let’s see, it says here there are 63 genders. As for races, I’m going to be very conservative, so to speak, and limit it to five (black, white, yellow, brown, and red). You do the math. Unless, of course, your math teacher didn’t match your race and gender, in which case no one can expect you to be able to do any arithmetic.
