Do smartphones help support learning in classrooms or are they a distraction that harms education? A growing number of governments have implemented restrictions on the use of smartphones in schools. Even without nationwide bans, many schools collect phones at the start of the day or insist on children keeping them in lockers during lesson time. Are the bans justified? In this episode of Top Class, OECD Editor Duncan Crawford speaks to two educators on opposing sides of the debate: Matt Miles, an American teacher and co-author of “Screen Schooled: Two Veteran Teachers Expose How Technology Overuse Is Making Our Kids Dumber” and Damian Maher, a senior lecturer from University of Technology Sydney, who backs the use of smartphones in schools.
