The concept of gender-role has great influence on girls who are in their childhood. The most influential one is expectations because of gender-role. For example, girls are not encouraged to be engaged in mathematics, or other subjects that are considered to be “fields of male.” As the result, a talent girl may probably stop learning deeply in this field. This causes the jobs of the field relating to these subjects such as engineering are occupied by males. Therefore, females are excluded from this kind of jobs. To be short, achievements of girls are restricted by these stereotypes and biased expectations.
