In school districts from Los Angeles to Philadelphia, parents shared how they are battling to put stricter limits on device-led learning.
The most common are tablets and laptops, such as iPads, Google Chromebooks and MacBooks.
Nationwide, some parents, educators and students told CNN they worry about bullying.
Also, worrisome is access to adult content and the use of artificial intelligence for cheating.
They say there is little evidence that devices are better learning tools than pencils and paper. (CNN)
