'Close to zero impact': US study casts doubt on effect of phone ban in schools

From: The Guardian

Strict bans on mobile phones in schools have “close to zero” impact on student learning and show no evidence of improvements in attendance or online bullying, a study has found.

Researchers at US universities including Stanford and Duke looked at nearly 1,800 US schools where students' phones were kept in locked pouches and found little or no differences in outcomes compared with similar schools without strict bans.

The report concluded that among schools instituting a ban: “For academic achievement, average effects on test scores are consistently close to zero.”

The results will come as a disappointment to teaching unions and campaigners in England who backed the government's recent move to restrict the use of mobile phones in schools. A ban is likely to come into force next year.

But Prof Thomas Dee of Stanford University's graduate school of education, one of the report's authors, said it would be wrong for policymakers to see the results as a reason to shy away from restrictions.

“One of the concerns I have about this study is that it might encourage people to walk away from phone bans as a compelling reform. And I think that would be a major mistake,” Dee told NPR.

“There are some encouraging results in the midst of these mixed findings. They are driving down phone usage, and as schools have longer experiences with phone bans, we're seeing a shift towards more positive outcomes.”

The study, published by the National Bureau of Economic Research, concentrated on secondary schools that required students to place their phones in magnetic pouches and found a substantial fall in phone activity by the third year of a ban based on GPS data analysed by the researchers.

But lower phone use did not translate into measurable improvements in student attainment or other non-academic outcomes.

“Average effects on standardized test scores are close to zero and precisely estimated, with similarly small and null effects on attendance, classroom attention, and perceived online bullying,” the researchers concluded, including relatively small “modest positive effects” on maths scores among older students and negative effects on younger pupils.

It also found a rise in suspensions and a dip in students' feelings of wellbeing in the first year after a ban as schools adapted to the change. “Over time, however, disciplinary impacts fade and wellbeing rebounds, becoming positive in subsequent years,” the report said.

'Close to zero impact': US study casts doubt on effect of phone ban in schools

From: The Guardian

Strict bans on mobile phones in schools have “close to zero” impact on student learning and show no evidence of improvements in attendance or online bullying, a study has found.

一项研究发现，学校严格禁止手机对学生学习的影响“接近于零”，且没有证据表明出勤率或网络霸凌状况有所改善。

bully /ˈbʊl.i/ 作名词，表示“恃强凌弱者，以大欺小者”，英文解释为“someone who hurts or frightens someone else, often over a period of time, and often forcing them to do something that they do not want to do”举个🌰：You're just a big bully! 你欺负人！

bully作动词，表示“伤害；胁迫；欺负，欺凌”，英文解释为“to hurt or frighten someone who is smaller or less powerful than you, often forcing that person to do something they do not want to do”举个🌰：Our survey indicates that one in four children is bullied at school. 我们的调查表明，有四分之一的孩子在学校受人欺负。

Researchers at US universities including Stanford and Duke looked at nearly 1,800 US schools where students' phones were kept in locked pouches and found little or no differences in outcomes compared with similar schools without strict bans.

来自斯坦福大学（Stanford）和杜克大学（Duke）等美国高校的研究人员，对近1800所美国学校进行了调查，这些学校将学生手机锁在专用袋中。结果发现，与未实施严格禁令的类似学校相比，这些学校的学生表现几乎没有差异。

pouch /paʊtʃ/ 表示“小袋；一小袋东西”，英文解释为“a bag or soft container for a small object or a small amount of something”。

The report concluded that among schools instituting a ban: “For academic achievement, average effects on test scores are consistently close to zero.”

报告总结指出，在实施禁令的学校中：“就学业成绩而言，对考试分数的平均影响始终接近于零。”

熟词僻义，作动词，表示“建立，制定（体系、政策等）；开始；实行”，英文解释为“to start or cause a system, rule, legal action, etc. to exist”举个🌰：She is threatening to institute legal proceedings against the hospital. 她威胁说要对该医院提起诉讼。

institute作名词，表示“研究所；学院”（an organization where people do a particular type of scientific, educational, or social work, or the buildings that it uses），如：the Massachusetts Institute of Technology 麻省理工学院（MIT）。

⚠️注意区分：institute & constitute：constitute 除了表示“组成”，等同于make up，还可以表示“构成，被视为，被算作”，英文解释为“If something constitutes a particular thing, it can be regarded as being that thing.”如：constitute a professional and legal offence 构成职业和法律犯罪；举个🌰： Failing to complete the work constitutes a breach of the employment contract. 不能完成工作被视为违反雇用合同。The rise in crime constitutes a threat to society. 犯罪率上升对社会构成了威胁。

The results will come as a disappointment to teaching unions and campaigners in England who backed the government's recent move to restrict the use of mobile phones in schools. A ban is likely to come into force next year.

这一结果可能会让英格兰的教师工会和活动人士感到失望，他们曾支持政府近期限制学校使用手机的举措。相关禁令可能于明年生效。

But Prof Thomas Dee of Stanford University's graduate school of education, one of the report's authors, said it would be wrong for policymakers to see the results as a reason to shy away from restrictions.

但该研究报告的作者之一、斯坦福大学（Stanford）教育研究生院的托马斯·迪（Thomas Dee）教授表示，若政策制定者因此结果而对限制措施望而却步，那就错了。

shy away from sth表示“（因不喜欢、害怕或缺乏自信而）退缩，躲避，畏避”，英文解释为“to avoid something that you dislike, fear, or do not feel confident about”举个🌰：I've never shied away from hard work. 我从未畏避过艰苦的工作。

“One of the concerns I have about this study is that it might encourage people to walk away from phone bans as a compelling reform. And I think that would be a major mistake,” Dee told NPR.

“我对这项研究的一个担忧是，它可能会促使人们放弃手机禁令这一引人注目的改革。我认为这将是一个重大错误，”托马斯·迪对美国国家公共电台（NPR）表示。

compelling /kəmˈpel.ɪŋ/ 1）表示“（理由、论证等）令人信服的，很有说服力的”，英文解释为“If a reason, argument, etc. is compelling, it makes you believe it or accept it because it is so strong.”如：compelling evidence 强有力的证据。

2）表示“引人入胜的；激动人心的；扣人心弦的”，英文解释为“very exciting and interesting and making you want to watch or listen”举个🌰：I found the whole film very compelling. 我觉得整部影片都很扣人心弦。

“There are some encouraging results in the midst of these mixed findings. They are driving down phone usage, and as schools have longer experiences with phone bans, we're seeing a shift towards more positive outcomes.”

“在这些好坏参半的结果中，也有一些鼓舞人心的发现。它们正在降低手机使用率，而且随着学校实施手机禁令的时间更长，我们看到结果正向更积极的方向转变。”

表示“正当…的时候；在…之中；当某事发生时；在某人做某事时”，英文解释为“while sth is happening or being done; while you are doing sth”举个🌰：She discovered it in the midst of sorting out her father's things. 她在整理父亲的东西时发现了它。I'm sorry but I'm too busy - I'm in the midst of writing a report. 恐怕我太忙了——我正在写一份报告。

📍2020年8月《经济学人》（The Economist）一篇讲述卡车业文章的标题就叫：The trucking industry is in the midst of upheaval—and hype 卡车运输业正在经历剧变，以及炒作。

The study, published by the National Bureau of Economic Research, concentrated on secondary schools that required students to place their phones in magnetic pouches and found a substantial fall in phone activity by the third year of a ban based on GPS data analysed by the researchers.

这项由美国国家经济研究局（National Bureau of Economic Research）发表的研究，聚焦于要求学生将手机放入磁性袋中的中学。研究人员根据全球定位系统（GPS）数据分析发现，在禁令实施的第三年，手机使用活动大幅下降。

bureau /ˈbjʊərəʊ/ 1）表示“（政府部门的）局，处，科”，英文解释为“a government organization”如：the Federal Bureau of Investigation 联邦调查局。

2）表示“（搜集或提供信息的）办事处，办公室，机构”，英文解释为“an organization or a business that collects or provides information”举个🌰：Her disappearance was reported to the police department's Missing Persons Bureau. 她的失踪被报到了警察局的失踪人口调查处。

substantial /səbˈstæn.ʃəl/ 1）表示“大的；可观的；价值巨大的；重大的”，英文解释为“large in size, value, or importance”举个🌰：The findings show a substantial difference between the opinions of men and women. 这些发现表明男性和女性之间存在着重大的意见分歧。

2）表示“基本上的；大体上的”，英文解释为“relating to the main or most important things being considered”举个🌰：The committee was in substantial agreement (= agreed about most of the things discussed). 委员会基本上达成了一致意见。

But lower phone use did not translate into measurable improvements in student attainment or other non-academic outcomes.

但手机使用量的减少，并未带来学生学业成绩或其他非学术成果的显著改善。

“Average effects on standardized test scores are close to zero and precisely estimated, with similarly small and null effects on attendance, classroom attention, and perceived online bullying,” the researchers concluded, including relatively small “modest positive effects” on maths scores among older students and negative effects on younger pupils.

研究人员总结道：“对标准化考试分数的平均影响接近于零，且估计精确，对出勤率、课堂注意力和感知到的网络霸凌的影响同样微小或为零。”其中，对年龄较大学生的数学成绩有相对较小的“适度积极影响”，而对年龄较小的学生则有负面影响。

perceive /pəˈsiːv/ 1）表示“感知，察觉，注意到，意识到”，英文解释为“to see something or someone, or to notice something that is obvious”举个🌰：He perceived a tiny figure in the distance. 他注意到远处有个很小的身影。

2）表示“认为；看待；视为”，英文解释为“to come to an opinion about something, or have a belief about something”举个🌰：How do the French perceive the British? 法国人是如何看待英国人的？

📍《经济学人》（The Economist）一篇讲述Bitcoin的文章中提到：Scarcity is a trait of many things that are perceived to have value. 稀缺性正是许多被视为有价值的事物共有的特征。

It also found a rise in suspensions and a dip in students' feelings of wellbeing in the first year after a ban as schools adapted to the change. “Over time, however, disciplinary impacts fade and wellbeing rebounds, becoming positive in subsequent years,” the report said.

研究还发现，在禁令实施后的第一年，随着学校适应这一变化，停学人数增加，学生的幸福感下降。“然而，随着时间的推移，纪律影响逐渐消退，幸福感反弹，在随后的几年中变为积极，”报告称。

suspension /səˈspen.ʃən/ 1）表示“暂停，中止”，英文解释为“the act of stopping something happening, operating, etc. for a period of time”

2）表示“（作为处罚的）暂令停职；暂令停学；暂令停止活动”，英文解释为“a punishment in which a person is temporarily not allowed to work, go to school, or take part in an activity”

3）表示“（车辆的）悬架，减震装置”，英文解释为“equipment attached to the wheels of a vehicle that reduces the uncomfortable effects of going over road surfaces that are not even”

dip /dɪp/ 1）表示“涮，浸，蘸”，英文解释为“to put something into a liquid for a short time”举个🌰：Dip the fish in the batter, then drop it into the hot oil. 先把鱼在面糊中浸一下，然后再放进热油中。

2）可以作名词，也可以作动词，表示“（通常指暂时的）减少，下降，衰退”，英文解释为“a decrease in the amount or success of sth, usually for only a short period”如：a sharp dip in profits 利润急剧下降。

📍diminish表示“（使）减少，（使）减小”（to become or make something become smaller or less）

📍dwindle /ˈdwɪndəl/表示“逐渐减少，缩小，变小”（to gradually become less and less or smaller and smaller）举个🌰：The factory's workforce has dwindled from over 1,000 to a few hundred. 该厂的工人总数已从1000多减少到了几百人。

fade /feɪd/ 作动词，表示“（使）褪色；（使）变暗；（使）衰弱”，英文解释为“to (cause to) lose colour, brightness, or strength gradually”举个🌰：If you hang your clothes out in the bright sun, they will fade. 衣服挂在光线强的地方晾晒会褪色。

在理发行业，“fade”指渐变式发型，通常用于描述极短或几乎剃光的发型，其中头发的长度从顶部到底部（通常是耳朵以下，包括两鬓和颈后）逐渐变短，最后接近或完全剃光。Fade发型可以进一步分为多种类型，包括低fade，中fade和高fade，这取决于fade开始的位置。

fade /feɪd/ away 表示“逐渐消失；变得无足轻重；变弱”，英文解释为“to slowly disappear, lose importance, or become weaker”举个🌰：The voices became louder and closer and then faded away again. 人声越来越嘈杂，越来越近，接着又逐渐消失了。
