On the Fact that (Again, According to Numerous Researchers; Lytton, Romney, Pinker, Eccles, Jussim, etc.) There Appears to Be No Sex-Specific Socialization Patterns in Grade School with the Vast Majority of Teachers (a Significant Percentage of Them Being Female) Basing Their Behavior Far More on Actual Performance and Motivation than on Gender Expectations

Yeah, this one never made a lot of sense (female teachers teaching down to female students) and, so, no, no big surprise here.
