In a study of children aged 2-5, parents interrupted their daughters more than their sons, and fathers were more likely to talk simultaneously with their children than mothers were. Jennifer Coates says: “It seems that fathers try to control conversation more than mothers… and both parents try to control conversation more with daughters than with sons. The implicit message to girls is that they are more interruptible and that their right to speak is less than that of boys.”
Girls and boys’ differing understanding of when to talk, when to be quiet, what is polite and so on, has a visible impact on the dynamics of the classroom. Just as men dominate the floor in business meetings, academic conferences and so on, so little boys dominate in the classroom - and little girls let them."
