Girls learn better from female teacher than men does

Article:

Some female teachers feel that being a woman is enough to encourage 

girls, and it isn’t necessary to do anything else. Some male teachers feel that it isn’t possible to reach girls so it isn’t necessary to try. Some adults and students feel that girls avoid classes taught by men.

it makes little difference to most students whether they are taught by a man or a woman.  It is the quality of the teaching, not the gender of the teacher that matters. While teachers treat male and female students differently, this is true for both female and male teachers.  The gender of the teacher has little or no effect on how they treat girls and boys. While women and men can teach girls well (or poorly), if students never see women teaching math or science, the myths about who does and doesn’t do math and science are reinforced. 

Opinion:

we tend to assume that females and males are different — are indeed “opposite sexes.”  We see someone’s sex as an important predictor of their abilities and interests and assume that if we know someone is a girl or a boy, we know a lot about them. That assumption is wrong!  Knowing someone’s sex may tell us a lot about them biologically but it tells us very little about them in other ways.  Knowing someone is a woman does not tell us if her athletic ability is closer to Martina Navratilova’s or a couch potato's.  Knowing someone is a man tells us nothing about whether his math skills reflect those of an Einstein or a math phobic. 

Conclusion:

Sex is not a good predictor of academic skills, interests or even emotional characteristics.  In fact, as the graph below indicates, sex is a bad predictor.
