In just two years since Florida initiated cellphone regulations in schools, half of U.S. states have followed suit. Legislators are increasingly addressing concerns that phones detract from students' focus and social interactions, framing these laws as necessary for mental health and public safety. States vary in their approaches, with some mandating full bans during school hours while others allow local districts to determine policies. Exceptions for emergencies and medical needs are common. Critics argue for teaching responsible use instead of outright bans, highlighting the tension between regulation and student autonomy.
