Posted earlier today.. quite a good discussion
I am great at reading maps but a horrible parker. What does that mean?? (My index finger is slightly longer than my ring finger. I am very fertile.)
I went into teaching earth sciences with the idea that anyone could master the subject if only confidence and attention were given, and I thought women were just steered away from it. Much to my chagrin, I had to admit to myself after a few years that (at least from the students taking this intro class for non-majors) there were fewer female students than male students who were able to easily pick up the three-dimensional nature of geology, and the extrapolation of subsurface morphology from surficial data.
It seemed that more male students could envision and mentally manipulate faults, folds, etc., although that doesn't mean all males could, nor did it mean I didn't have excellent female students. I don't think it was my teaching technique was biased, and in other portions of the class, I think that women were more likely to do well.
