A new working paper using data from 4,600 schools finds that bans on phones and other electronic devices in classrooms produced virtually no net change to test scores, with effects described as close to zero overall. The study also reported no meaningful shifts in bullying, attendance, or self-reported attention. The findings come as at least 37 states and Washington, D.C. have implemented phone bans and districts have spent substantial sums on enforcement tools such as phone pouches. Researchers report slightly positive test effects concentrated in high schools, and slightly negative results in middle schools. The study adds to ongoing debates about whether classroom device restrictions improve learning outcomes or whether other instructional and digital factors are responsible for broader score declines. For higher education leaders involved in teacher preparation, curriculum, and K-12 partnerships, the results emphasize the need for evidence-based approaches when campuses and feeder districts adjust classroom technology policies.
