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.

And when they do ask for help, they're less aggressive 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 they've gotten at

home. As a rule, working class parents coach 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 them to be proactive, even to interrupt their teachers

for help.

The result is that teachers were more likely to attend to the assistant seekers and louder class

participators, which left working class kids behind and magnified inequalities.

So the working class child's behavior, which they and their parents see as respectful, could impair their success in the classroom and prevent them from joining their classmates in higher

social classes.

Thanks for the minute.
