Full‑Day School Device Bans

A national education authority can extend device bans beyond lessons to the entire school day—covering recess, co‑curricular activities and supplemental classes—and include smartwatches as prohibited devices. Singapore will require phones to be stored (lockers or bags) and will move school‑issued device sleep defaults earlier, citing wellbeing gains from prior primary‑school trials. — If adopted widely, full‑day bans change how societies balance child autonomy, school authority, and digital access, and will become a real‑world experiment about whether hard restrictions improve wellbeing, learning, or social interaction.
