"Beyond the learning impact, the second issue most often cited for banning cellphones in the classroom is the negative impacts of mobile use on wellbeing. The access to and reach of harmful contexts (such as porn) and acts (like bullying) is certainly a serious and significant issue. The pervasiveness of cellphones heightens the risks. Banning cellphones does not solve this issue and rather just enables schools (and the government) to absolve themselves from dealing with the problem, pushing these complex issues into the hands of parents and whānau to deal with."
