Working-class kids ask for help from teachers less often and less aggressively (攻击性的)than do their middle-class counterparts(相对应的人)
Kids from different economic backgrounds behave differently in classrooms. For example, working-class kids are less likely to ask for help from teachers than are their middle-class counterparts(相对应的人). And when they do ask for help, they’re less aggressive(好斗的) about it. That’s according to a study that followed students from the third grade through the fifth, published in the journal American Sociological Review.
Part of the difference in how kids act comes from the guidance (监护人)they’ve gotten at home. As a rule, working class parents coach(说教) their kids to work out problems on their own. And if the kids did ask for help, it was in subtle ways—like sitting quietly with a hand raised. Middle class kids? Their parents urged(怂恿) them to be proactive(有前瞻性的), even to interrupt their teachers for help.
The result is that teachers were more likely to attend to the assistance-seekers(寻求着) and louder class-participators，which left working class kids behind and magnified (放大的)inequalities. So the working class child’s behavior, which they and their parents see as “respectful,”(恭敬的) could impair their success in the classroom. And prevent them from joining their classmates in higher social classes.
