Fifty-two third and fourth grade teachers were asked to consider boys'
and girls' performance in mathematics, giving their views on the reas
ons for the pupils' successes and failures and describing their learni
ng characteristics. The girls and boys included low, average and high
achievers in mathematics. Teachers thought that their low and average
achieving girls were less logical than equally achieving boys. The gir
ls were thought to profit less than boys from additional effort and to
exert relatively more effort to achieve the level of actual performan
ce in mathematics. Teachers rated mathematics as more difficult for av
erage achieving girls than for equally achieving boys. With regard to
girls, teachers attributed unexpected failure more to low ability and
less to lack of effort than with boys. Low achieving girls were expect
ed to do less well in future in mathematics than low achieving boys. T
eachers were aware of the girls' lower self-concept of mathematical ab
ility. The results increase our understanding of stereotypical teacher
expectations that might explain gender differences in performance and
in subsequent occupational choices.
