"Children are growing up today [with] the iPad used as a device for entertainment. So when the iPad comes into the classroom, then there's a shift in everybody's thinking."
And sometimes that shift is hard for everybody. Hobbs says this isn't the first time educators have tried to co-opt things that lots of people use for fun.
"Back in the 1930s, there was a big initiative to use radio in education," says Hobbs. "It was the original distance education." But, Hobbs says, that all fizzled out.
"Within a decade, we discovered that the commercial use of radio, for soap operas and music shows and game shows, actually eclipsed the educational use of radio. And the entertainment function is just so [dominant]. You can't compete," Hobbs says.
