In his April, 2016, article for The Atlantic, high school teacher Paul Barnwell writes of his own experiences with allowing students use of cellphones in schools. He reports common problems, no doubt much like those other teachers have encountered, where cellphones distract students from the work at hand. He also considers research that suggests that how cell phones are used depends on the kind of students involved. He quotes from a study done at the London School of Economics: ‘“We find that mobile phone bans have very different effects on different types of students,” the authors wrote. “Banning mobile phones improves outcomes for the low-achieving students … the most, and has no significant impact on high achievers.”’
