I give my children unfettered access to technology. It is very much a last resort for them, only picking up a device when they have exhausted all other visible opportunity to do something more interesting. Suggesting that they do almost anything else is met with "Yeah! Let's do that!"

If a student is reaching for their phone in class, the problem is with something about the class. Being old, cell phones came in giant bags when I was a student, but we played with our calculators, doodled, or anything else to stave off the same boredom when we had a horrible teacher who had no clue as to what they were doing. The phone is just a more modern version of the exact same quest for distraction.

I think the point is that we need to question why we are wasting our students' time in classes which are not providing value. There is a lot of sentimental attachment to school, but ultimately there is no need for make work projects. The focus needs to be on delivering value and where that is not being delivered a rethink is necessary.

Phone use, or any such distraction, is a symptom telling us that there is a problem in value delivery. Suppressing a symptom does not cure the illness.
