With 91% of teens owning a smartphone, today’s classroom challenge is less about whether phones are present and more about what they do once the first lesson starts. From state bans that now cover 33 states plus DC to 59% of students being asked to put phones away at least sometimes, the gap between policy and day to day reality is where the real tension shows up. This post pulls together the latest research on focus, discipline, and cyberbullying to explain why one small device can ripple across academic performance and student safety.
