Smart phones are mobile devices that allow users to make calls and also have features of personal digital assistants and computers, like email and editing Office documents. While smart phones improve communication between students and teachers, they can also be a distraction from learning when used for non-educational purposes. In the workplace, smart phones increase accessibility but can reduce focus if misused for personal matters. Productivity can be enhanced by accessing work remotely, but mobile devices also present security and information theft risks if stolen. While smart phones connect people worldwide, overuse has been linked to health issues and less engagement with family. Overall, smart phones are useful tools when limits are set for appropriate school, work, and social usage.
