Pew Internet Research first surveyed teenagers about their mobile phones in 2004 and results showed that 45% of teens had a cell phone. Since then mobile phone use has climbed steadily among teens to 63% in \n2006 and 71% in 2008.
Surprising field studies suggest cell phones could be effective learning tools
In most schools, cell phones are checked at the door -- or at best powered off during school hours in a tacit "don't ask, don't tell" understanding between students and administrators. This wide-spread technology ban is a response to real concerns: if kids have unfettered instant access to the Internet at school, how do we keep them safe, how do we keep out inappropriate content, how do we prevent real-time cyberbullying, how do we even keep their attention in class when competing with messaging, gaming, and surfing?
