„Students who spend up to one hour per day on digital devices for learning activities in school scored 24 points higher in mathematics than students who spend no time on such devices, on average across OECD countries. Even after accounting for students’ and schools’ socio-economic profile, the former group of students scored 14 points higher. […] However, the relationship becomes negative when students spend more than one hour per day on digital devices for learning in school.“
