One thing evident from the #PISA data is that allowing phones in the classroom is not good for student learning. Two things stand out: 1.Almost a third of students report being distracted by phones in class: “around 30% of students, on average across OECD countries, reported that, in most or every mathematics lesson, they get distracted using digital devices” 2.Even students who are NOT using phones get distracted by others who use them: “Equally important, around 25% of students indicated that, in most or every lesson, they become distracted by other students who are using digital devices, that the teacher has to wait a long time for students to quiet down, that students cannot work well and that students do not start working for a long time after the lesson begins.
