Brazil bans smartphones in schools to aim for better learning
Brazil’s nationwide school smartphone ban is already showing results, and Stanford-led research offers an early look at why. In surveys of more than 3,000 students, teachers, and administrators across all 26 states, 83% of students said they’re paying more attention in class since the law took effect. Younger kids are adapting fastest — 88% of elementary students reported sharper focus, compared with 70% of high schoolers. Researchers also found that the schools seeing the biggest shifts gave students a dedicated spot to stash their phones, suggesting physical separation matters more than rules on paper. As dozens of countries weigh similar policies, Brazil’s real-time experiment is becoming a rare evidence base for what actually works.
