Not long ago, kids could get in trouble for using their cellphones during class. Today, some middle- and high-school teachers encourage it -- as long as students are using the devices for classwork.
Teachers don't mind -- heck, they're using their smartphones for school as much as students.
In fact, close to three-quarters of teachers in a recent survey say they or their students use cellphones in class or for homework.
And cellphones aren't the only mobile devices teachers and students are using at school. Of the of 2,462 U.S. middle- and high-school teachers in a Pew Research Center Internet & American Life study, close to half (45%) say they or their students also use e-readers, and almost as many (43%) use tablet computers, either in class or to work on assignments. "That’s more than we thought it would be," says Kristen Purcell, the director of research for the Pew Research Center Internet & American Life Project and a co-author of the report.
