New study finds school cellphone bans alone do not lift grades or wellbeing — what Thai schools should know
A major new study of secondary schools in England finds that banning smartphones on school grounds or at break times does not, by itself, produce better grades, healthier sleep or improved mental wellbeing among pupils — a result that shifts the debate from banning devices to reducing total screen time and reshaping how young people use digital technology. Researchers compared student outcomes across schools with different phone rules and found that the single strongest predictor of worse academic and health measures was the amount of time pupils spent on smartphones and social media, rather than whether schools imposed on-site bans. The finding matters for Thai educators and parents because it suggests policy and cultural interventions beyond simple exclusion are needed to protect learning, mental health and social development in a country where young people are highly connected.
