The principal of New Milford High School has nearly 12,300 Twitter followers. He and his teachers use Facebook to communicate with students and parents，and students use it to plan e-vents. In class, teachers routinely ask kids to power up their cellphones to respond to classroom quizzes. Rather than ban cellphones, Sheninger calls them "mobile learning devices".
"The Internet as we know it is the 21st century," he says. "It is what these students have known their whole lives. They're connected, they're creating, they're discussing."
He and others say working online also pushes education beyond the limits of school, allowing kids to broaden discussion of their work. And it forces them to do "authentic" work that gets tested out in the real world, as outside viewers see it and respond to it.
"Being literate in 2011 means being digitally literate. " says Chris Lehmann. "It is naive (天真的) to think that kids raised online will respond to school the same way as previous genera?tions. Kids are coming to us bored, disconnected, and it's a challenge for us to figure out how to use the tools inherent in the real-time Web.”
Perhaps the biggest objection to widespread use of social sites is the likelihood that kids will meet irrelevant or even offensive material―a fear that many teachers say is overblown.
"We as educators need to do a better job of advertising and sharing the meaningful work done with social media," says Matt Levinson. "If you keep it out,kids are creating their own cultures in this space with no guidance from adults―and that's not responsible.”
"The other big misconception is that schools with open Web access are simply letting kids play freely as if there's no structure," says Lisa Highfill, a longtime devotee of YouTuhe. She used it recently to show her students videos of tornadoes. Highfill says she chooses videos in ad?vance.
"I don't just search in front of the kids," says Highfill. She admits that even with careful planning，learning online carries risks. But the risks shouldn't be overstated. " When we go on a field trip,when we go anywhere," she says, "we warn students of the dangers of where we're going.”
