<p>So much has transpired on this thread since I last intervened on it that I hardly know where to start. I think I should reiterate a fundamental point, however, that tends to get overlooked whenever we get into comparing one class ("boys") with another ("girls"). Within both classes one will find enormous variation in quantitative, spatio-temporal, interpretive, and other skills. While as a long-time teacher, I think that roughly 90% of the time I can figure out just from handwriting whether the author of a bluebook essay is male or female, I wouldn't dare begin to characterize mental faculties from observing the "products," whether this be what the student writes in an essay, which problems he or she can solve, or how well he or she has designed something. While there may be "tendencies" associated with sex, I would make a whole lot more errors of inference about the sex of the student if I had to go by their work rather than their handwriting.</p>
<p>Many many things go into such work outcomes. My son, as bright as he may be solving logical and mathematical problems, just has very poor small motor skills -- and his large motor skills aren't so hot either. Though he's a great "fan" of baseball and its logical and mathematical analysis, I wouldn't pick him for my team if what I needed were players. There are plenty of klutzes among the male population of the world, and, BTW, these aren't necessarily "effeminate" guys.</p>
<p>On the other hand, you would be amazed at the logical and visual acuity of my daughter, who nobody would ever remotely describe as "masculine." An ability to anticipate multiple "folds" needed in clay to produce an image of a character (say "Big Bird") was something she showed at a rather young age. Imagine inventing origami in clay -- that's what she taught herself to do. And she had the hand-eye coordination, both small motor and large motor, to do what she "thought through."</p>
<p>I wouldn't dare impute some underlying "hormonal" basis of either of their abilities or disabilities, nor would I quickly assert any such generalization about "men's" and "women's" success in constructing things, designing things, using language, solving problems, or, for that matter, keeping the crayon colors within the lines. </p>
<p>Further, because there are so many factors that are external to the "organism" that affect how that individual develops interests and performs various tasks, I would strongly prefer not to jump to stereotyping or to assuming that behavior is all determined by genetics. In this connection, some very interesting research has been conducted on the concept of "stereotype threat," in which anxiety about being stigmatized can impede performance -- whether mathematical, athletic, or "tests" in general. Much of this has been authored by the psychologist Claude Steele and his students and desciples. (For a link to his CV, go here: <a href="http://psychology.stanford.edu/%7Esteele/%5B/url%5D">http://psychology.stanford.edu/~steele/</a> ). One reason women in women's colleges seem to do better than they perform in "mixed" settings is not the "boys don't make passes as girls who wear glasses" phenomenon (or the estrogen theory endorsed on a previous thread), but rather that they are not as likely to suffer anxiety from arguing aggressively or energetically or being put on the spot in a class discussion. Change the social situation, the expectations of the context, and women suddenly get smarter? No, their performance, and perhaps over time their ability to learn, is affected by social expectations. A similar phenomenon seems to be at play in accounting for differences in performance in standardized tests. In experiments, "white guys" who according to independent pretests may be just as capable in math as "Asian guys," can be induced in some situations to underperform when told that they aren't "expected" to do as well as the Asian guys.</p>
<p>When I intervened early on this thread (long after posting the link to Newsweek story), my concern was that we were attributing too much of the performance differences in school to the curriculum or to the biases of teachers, and not enough to the broader social context. Now, it seems, some are advocating a kind of biological determinism that is belied by observations of the great variety of performances within the male and female sexes and by the ability to train or induce better or worse performance through the application of social or societal stigmata or sanctions.</p>
