„PISA 2022 data show that many students study mathematics in a disciplinary climate that is not favourable to learning […] Apart from ‚traditional‘ disciplinary problems, such as students not listening to what the teacher says, or trying to learn in a noisy and disorderly classroom, one in three students, on average across OECD countries, also reported that, in most or every mathematics lesson, they get distracted using digital devices.“
