I've always thought that if we focused more on teaching in high schools and students were already educated at home, we would see exponential improvements in results. If we look ridiculous in the PISA reports, it's because learning the content is no longer prioritized. This is unthinkable at university. I have a relative who is a university professor, and I asked him how he handled the issue of cell phones, now that we've banned them in secondary school because they're distracting. He confessed to me that many of his students don't even know their names. He teaches classes without taking attendance, and sometimes they take notes, sometimes they fall asleep, and sometimes he sees how they waste time on their phones. The red line is not to interrupt the teacher's concentration. Therefore, the priority is "teaching."
