Home Influences:
•Jacquelynne Eccles and her colleagues (1990) have conducted
a number of studies aimed at understanding why girls tend to
shy away from math and science courses and are
underrepresented in occupations that involve math and science.
They find that parental expectations about sex differences in
mathematical ability do become self-fulfilling prophecies.
•Parents, influenced by gender stereotypes, expect their sons to
outperform their daughters in math. Even before their children
have received any formal math instruction, mothers in the United
States, Japan, and Taiwan express a belief that boys have more
mathematical ability than girls (Lummis & Stevenson, 1990).
•Children begin to internalize their parent’s views, so that boys
feel self-confident whereas girls are somewhat more inclined to
become anxious or depressed and to underestimate both their
general academic abilities (Cole et al., 1999; Stetsenko et al.,
2000), and, in particular, their proficiencies in math (Fredricks &
Eccles, 2002; Simpkins et al., 2006).
•In fact, girls whose parents are nontraditional in their gender-role
attitudes and behaviors do not show the declines in math and
science achievement that girls from more traditional families are
likely to display (Updegraff, McHale, & Crouter, 1996).
•The negative effects of low parental expectancies on girls’ self-
perceptions are evident even when boys and girls perform
equally well on tests of math aptitude and attain similar grades
in math (Eccles, Freeman-Doan, Jacobs, & Yoon, 2000;
Fredricks & Eccles, 2002; Tennenbaum & Leaper, 2002).
Scholastic Influences:
•Teachers also have stereotyped beliefs about the relative
abilities of boys and girls in particular subjects. Sixth-grade math
instructors, for example, believe that boys have more ability in
math but that girls try harder at it (Jussim & Eccles, 1992).
•Girls, to a greater extent than boys, tend to be generalists at
school, striving to do well in most or all of their classes. Thus,
girls may be less likely to become exceptionally proficient in any
subject (particularly in “masculine” subjects like math and
science) when their time, energies, and talents are so broadly
invested across many academic domains (Denissen, Zarrett, &
Eccles, 2007).
