过去几年，某国已有大约三十六个州在学校实施了手机禁令，且很可能有更多州跟进。这些禁令被大肆宣扬为改变教育格局的利器。手机使用确实减少了，但考试分数没有明显变化，违纪行为短期反而上升，对霸凌和学生注意力也没有可证实的效果。说白了，几乎没什么改变。

In the past several years, about three dozen states have instituted phone bans in schools, and more are likely to follow.These bans have been trumpeted as game changers. Phone usage went down, but test scores didn't change much, disciplinary infractions increased in the short term and there was no demonstrable effect on bullying or student attention. Basically, not much changed.
