“Curious brains are better at learning not only about the subject at hand but also dull information.This is a phenomenon teachers can use in the classroom.”says Evie Malaia,a professor.“Say a kid wants to be an astronaut,” she says.“Well,how do you link that goal with learning multiplication tables(乘法表)?” “A teacher may choose to ask her class an interesting problem that involves space exploration,”Malaia says.Students may remember the answer to the problem,but they’ll also remember how they found the answer through multiplication.
What Ranganath wants to know most is why some people seem naturally more curious than others.Lots of factors,including stress,aging and certain drugs can affect dopamine(多巴胺) processing in the brain.“If we could figure these things out,we could help those who may just seem bored,” Ranganath says.
Blackwell says she doesn’t have to deal with that problem
too often.She says her students love exploring the mysterious unknowns in science:What happens when a car crashes?How do rainbows work?
“I tell my kids there’s no dumb questions,” Blackwell says.“That’s science:asking questions and seeking answers.”

A.The students were often burnt by accident.
