I think this is a great idea — in fact, if I were a parent of young children, I’d keep them off cellphones entirely — but I suspect this will go nowhere.

Two Greenwich moms want schools to ban cellphones 'bell to bell;' 700 people signed petition for it

"Every hour that (kids are) on that is preventing them from exploring a hobby that at 11, 12 and 13 years old, they need the chance to explore who they are and what they like and what they don't like, not spend all that time scrolling, having the internet tell them who they are, what they like, what they don't like, how they should feel about themselves," she said.

"We believe that the current 'not during class' practice is not enough and implementing a phone-free policy (bell to bell) will enhance the educational experience for all students in Greenwich Public Schools," the petition reads. "We respectfully request that the Board of Education take this step toward improving our children's learning environment and overall well-being."

I read an increasing number of studies that detail the horrendous effects social media, sped along by cellphones, has had on young children over the past decade-and-a-half, and i think it’s a tragedy. There’s no putting this particular technological genie back in the bottle, but delaying children’s exposure it might help mitigate the damage.
