Full school day cellphone bans are more popular than ever

全天候校园手机禁令比以往任何时候都更受欢迎

As schools across the country continue to implement cellphone bans, a new Pew Research Center survey shows they continue to gain support. 随着全国各地的学校继续实施手机禁令，皮尤研究中心（Pew Research Center）的一项新调查显示，这些禁令的支持率持续上升。

Seventy-seven percent of US adults support banning cellphones in middle and high school classes, and 48 percent support banning them for the entire school day. That’s the first time more Americans have supported, rather than opposed, so-called bell-to-bell bans. Two years ago, just 36 percent of American adults supported an all day ban. 77%的美国成年人支持在初中和高中课堂上禁用手机，48%的人支持在整个上学期间禁用手机。这是首次有更多的美国人支持而非反对所谓的“全天候”（bell-to-bell）禁令。两年前，仅有36%的美国成年人支持全天禁令。

Across all age groups over 18 that were surveyed, most respondents support in-class bans. That support is lower but still at least half for all-day bans across most age groups, except for ages 18-29, where support for a bell-to-bell ban drops to just 28 percent. Republicans were slightly more likely to favor both in-class and all-day bans, at 81 percent and 55 percent, respectively. But Democrats were also broadly supportive of in-class bans at 74 percent, and all-day bans at 44 percent. 在所有受访的18岁以上年龄组中，大多数受访者支持课堂禁令。对于全天禁令，除18-29岁年龄组外，大多数年龄组的支持率虽有所下降，但仍至少达到半数；而在18-29岁年龄组中，对全天禁令的支持率降至仅28%。共和党人对课堂禁令和全天禁令的支持率略高，分别为81%和55%。但民主党人也广泛支持课堂禁令（74%）和全天禁令（44%）。

More than 20 states have already adopted bell-to-bell cellphone bans, and early studies show mixed impacts. One report found positive long-term effects on students’ well-being, but no evidence of an impact on test scores. Another found higher suspension rates in the first year of a ban, that later returned to normal levels, and a decrease in unexcused absences. 目前已有超过20个州采取了全天候手机禁令，初步研究显示其影响好坏参半。一份报告发现，这对学生的长期心理健康有积极影响，但没有证据表明其对考试成绩有影响。另一份报告则发现，禁令实施的第一年停学率有所上升，随后恢复到正常水平，同时无故旷课的情况有所减少。
