Great - let's hear the measurable benefits then.

How much higher will Czechia's score be on the next PISA test based on this?

France:

>Mobile phones have been prohibited for students from 3 to 15 years of age, since September 2018, although they were first banned in classroom time in 2010.

French PISA results for math, science, reading:

* 2022: 474, 487, 474

* 2018: 495, 493, 493

* 2015: 493, 495, 499

* 2012: 495, 499, 505

* 2009: 497, 498, 496

I'm really impressed by the improvements of nothing.

You assume there are no other factors at play and those numbers wouldn't be worse if not for the ban. You also cherry-picked one example only. There are others that show immediate improvements in test results.

This is NOT how an intelligent person draws their conclusions. It's Facebook-level fear mongering, not worthy of HN.
