I have had a few jewish teachers in K-12 school, and I have noticed a pattern among them:
The jewish teachers were particularly insistent upon homework.
They assigned more of it, based a larger portion of their grades upon it, and could be aggressive
toward students who didn't do it. Not all white teachers were innocent of such behavior either,
but it was uncommon among them.

I know the innate psychological reason for this:
Jews, on average, have a stronger desire to assert dominance than whites do.
Hence, jews exhibit such dominance-asserting behaviors as homework slavery,
foreskin amputation, prescribing SRI drugs so as to cause PSSD, keeping a religious book-
the Torah, that calls for the execution of various types of innocent people, and other things.
