Kansas Schools Now Collect Phones at the Door – Spends $180K On Smartphone Lockers

Are there any studies that link phone use inside schools to those issues? Because I can easily believe that declining grades could be attributed towards the use of tablets and laptops being used in classrooms as well which many schools are encouraging or increasing the use of.
As for attention spans I would believe it's for the use of phones/tablets/electronics from a young age rather than the use of them inside of a school itself.
