“…The reasons for the differences in these individual characteristics are primarily found in gender-speci®c developmental environments (and therefore again in a differential socialization, which is why Yewchuk et al, 2001, see above, can only be partially accepted): for example about one-third of the high school physics and mathematics teachers, both male and female, voiced the opinion that boys are better suited for their classes than girls (Ziegler et al, 1998;Heller et al, 2001); teachers also describe gifted girls as being more diligent and more conscientious workers, but award boys, however, with higher report card grades (see Kerr, 2000). Parents expect their gifted daughters to achieve well in all school subjects, including mathematics and the natural sciences; all the same, they deem these domains as being hardly relevant for later careers for their daughters (Noble, 1989); in addition they``discover'' concrete talents in their daughters more infrequently, and if they do, the reaction more often is`o verprotective'' (Kerr, 2000).…”
