Smartphones are an integral part of teenager lifestyle today. A study was undertaken by the Pew Research Centre in Washington D.C. to understand how teenagers interact with and are affected by Smartphone usage.

The study revealed that 73% of teenagers in the United States had ready access to a smartphone. In the majority of cases they own their own phones. 92% of these teenagers reported go online every single day. In fact one forth of them claim to be online almost constantly.

They tend to send a median number of 30 texts in a day. Remember some may be higher and others lower than this median figure, but it is still a fairly large number of texts. This texting, tweeting and posting took place both inside and outside the classroom.

Another study was to conducted by the researchers at Miami University Middletown in Ohio. They restricted the control group to no texts, another group to limited texts related to the class and another group could text as much as they wanted. Students were then made to watch a video.

Later they were given a test on the material on the video and it was found that the control and limited text groups did 70% better on average compared to the group that could text as much as they liked. This science project proves that what teachers have been saying in the class for years.
