Students perform less well in final exams if smartphones are allowed in class, for non-academic (非学业的) purposes in lectures, a new study in Educational Psychology finds. Students who don’t use smartphones themselves but attend lectures where their use is acceptable also do worse, suggesting that smartphone use damages the group learning environment.
Researchers from Rutgers University in the US performed an in-class experiment to test whether dividing attention between smartphones and the lecturer during the class affected students’ performance in within-lecture tests and a final exam. 118 students at Rutgers University took part in the experiment during one term of their course. Smartphones were not allowed in half of the lectures and allowed in the other half. When smartphones were allowed, students were asked to record whether they had used them for non-academic purposes during the lecture.
The study found that having a smartphone didn’t lower students’ scores in comprehension tests within lectures, but it did lower scores in the final exam by at least 5%, or half a grade. This finding shows for the first time that the main effect of divided attention in the classroom is on the length of time in keeping memory, with fewer things of a study task later remembered. In addition, when the use of smartphones was allowed in class, performance was also poorer for students who did not use them as well as for those who did.
The study’s lead author, Professor Arnold Glass, added: “These findings should alarm students and teachers that dividing attention is having a not obvious but harmful effect that is damaging their exam performance and final grade. To help manage the use of smartphones in the classroom, teachers should explain to students the alarming effect—not only for themselves, but for the whole class.”
This is the first-ever study in an actual classroom showing a relationship between losing attention from smartphones and exam performance. However, more researches are required to see how students are affected by using smartphones after school.

¨We generally found that media use is not a source of conflict in the home" for families with young children, Ellen Wartella, a researcher from Northwestem University, told USA Today. She led a survey of 2,326 parents who have children 8 and younger.It found that in 80 percent of families, children's media use was not a problem, with 55 percent “not too" or“ not at all" concerned about it. It also showed parents have more positive than negative feelings about how media consumption affects a child's learning and the development of creativity.The exception is video games, which are viewed more negatively than TV, computers or mobile devices.“Parents rated video games as more likely to have a negative effect on children's school performance, attention time, creativity, social skills, behavior and sleep than any other medium," the researchers said in a news conference about the survey.
¨The findings exposes a generational shift (转移) in parental attitudes about technology's role in young children's lives," said Wartella.“Today's parents grew up with technology as a central pact of their lives, so they think about it differently than earlier generations of parents, instead of a battle with kids on one side and parents on the other, the use of media and technology has become a family affair. "
The researchers identified three media environments created by parents: media-centric (39 percent of families) , media-moderate (45%)and media-light (16%). Children in media-centric families spend at least three hours more each day watching TV or using computers, video games and tablet PCs don't make parenting easier.And 88 percent of parents say they are most likely to turn to toys or activities to keep their children occupied.Slightly fewer turn to books (79%) and TV(78%).
The survey didn't look at how media affects children. That's a topic that the American Academy of Pediatrics has handled a number of times. The AAP says studies have found too much media use can lead to attention- problems, school difficulties, sleep and eating disorders and being fat. In addition, the Internet and cell phones can provide platforms for illegal and risky behaviors.¨By limiting screen time and offering educational media and non-electronic formats (格式)such as books, newspapers and board games, and watching television with their children, parents can help guide their children's media experience. Putting questionable content into context and teaching kids a 70 out advertising contributes to their media literacy (素养) ," it says.
The pediatricians' group says parents should have “screen-free zones" and TV should be turned off during dinner. At most, it recommends children and teens engage with entertainment media for no more than two hours a day and that should be high-quality content. It is important for kids to spend time on outdoor play, reading, hobbies and using their imaginations in free play.“ Kids under 2 should not use television and other entertainment media because their brains are developing quickly and they learn best from direct human interaction," the group says.
An article on screen time by t.he Mayo Clinic also notes problems linked t.o over screen time, including being fat, irregular sleep , behavioral problems , weak school performance , violence and less time for active and creative play.

【推荐2】Few social networking platforms are known for inspiring positive social change these days, but an Inuit-developed app is helping local communities from Alaska to Greenland advance their self-determination.
Named SIKU after the Inuktitut word for “sea ice”, the app allows communities in the North to pull together traditional knowledge and scientific data to track changes in the environment, trace local wild foods, and make decisions about how to manage wildlife.
Over the years, SIKU has stepped forward in its development. Recently, the elders saw that the platform could help address a familiar challenge: sharing knowledge with younger people who often have their noses in their phones. In 2019, SIKU relaunched as a full-fledged social network—a platform where members can post photos and notes about wildlife sightings, hunts and sea ice conditions. The app operates in multiple languages, such as Inuktitut, Innu and Greenlandic. Since early 2024, over 25,000 people from at least 120 communities have made more than 75,000 posts on SIKU.
The app is also equipped with useful tools for life on the ice, including weather reports, sea ice forecasts, and other critical safety information. “When I go out on the land with family, we go a long distance, and the SIKU app can show which area we are in. It’s precise.” says Karen Nanook, who lives in Taloyoak, Nunavut.
The data held in SIKU is abundant and up to date, and communities are already using the app to inform important decisions. In 2021, for example, elders in Sanikiluaq were worried the local reindeer population had thinned, so the Hunters and Trappers Association used SIKU to survey hunters and look at recent reported harvest rates. The analysis led the association to temporarily close the hunt to relieve pressure on the population and to reintroduce hunting slowly once the number of reindeer increased. This decision shows how Inuit can use the technology in combination with traditional wildlife management. “It’s part science and part Inuit knowledge. It can work both ways, instead of one dominating the other,” says Arragutainaq, a manager at the association.

【推荐1】It's 10:30 pm, and 11-year-old Brandon Blanco is sound asleep at home. Suddenly, a loud noise wakes him up. Naturally, Brandon reaches for his cell phone. The message becomes clear: "R U awake?"
Brandon' s use of technology doesn' t stop there. He also has a computer, a TV and three video-game consoles (控制台 ) in his room. With so many choices, it' s no surprise that when he isn' t at school, he spends nearly every waking minute using one or more of these devices. Brandon is hardly alone. According to a recent study by the Kaiser Family Foundation, kids aged 8 to18 are spending more time than ever before using electronic devices. How much time? More than seven and a half hours a day on average, the study found.
The jump is the result of a huge explosion in mobile devices, says Victoria Rideout, the lead author of the study. Today, nearly seven out of ten kids have cell phones. Just five years ago, it was four out of ten.
Often, kids multitask, or use more than one device at a time. " If you’ve got a chance to do something on your computer and take a phone call and have the TV on in the background, why not?" media expert Cheryl Olson says.
Most experts agree technology has much to offer kids. But some worry the kids could be missing out on other activities like playing outside or hanging out with friends. " It' s a matter of balance," says Olson." You’ve got to work on it. "
Multitasking while doing homework is another concern. Some kids listen to music, watch TV or use the phone while doing their homework. "It' s important to make sure that you can stop and concentrate on one thing deeply, " says Rideout.
With new and exciting devices hitting stores every year, keeping technology use in check is more important than ever. " Kids should try," adds Rideout. " But parents might have to step in sometimes. "

【推荐2】Running out of money
In spite of the second biggest city in the UK, Birmingham announces it has been bankrupt (破产的)on November 5th. Birmingham City Council (市政委员会), which looks after services in the city, says that it can no longer pay for its planned costs. These costs add up to around 3. 2 billion pounds per year.
Local people’s lives are now under pressure. As of November 4th, local workers have stopped collecting garbage because the council couldn’t pay for the garbage trucks’ fuel.
Birmingham is the seventh council to have gone bankrupt in the UK. In the coming months, around 1 in 10 local governments in the UK may do the same, said SIGOMA, a group of 47 councils in England.
Birmingham is an example of the very bad performance of the UK economy, said John Ross, a UK expert who works at London University.

【推荐3】Why do so many Americans distrust what they read in their newspapers? The American Society of Newspaper Editors is trying to answer this painful question. The organization is deep into a long self-analysis known as the journalism credibility project.
Sad to say, this project has turned out to be mostly low-level findings about factual errors and spelling and grammar mistakes, combined with lots of head-scratching puzzlement about what in the world those readers really want.
But the sources of distrust go way deeper. Most journalists learn to see the world through a set of standard patterns into which they report each day’s events. In other words, there is a traditional story line in the newsroom culture that provides a backbone and a ready-made narrative structure for otherwise confusing news.
There exists a social and cultural disconnect between journalists and their readers, which helps explain why the “standard patterns” of the newsroom seem foreign to many readers. In a recent survey, questionnaires were sent to reporters in five middle-size cities around the country, plus one large metropolitan area. Then residents in these communities were phoned at random and asked the same questions.
Replies show that compared with other Americans, journalists are more likely to live in upscale neighborhoods, have maids, own Mercedeses, and trade stocks, and they’re less likely to go to church, do volunteer work, or put down roots in a community.
Reporters tend to be part of a broadly defined social and cultural elite (精英), so their work tends to reflect the traditional values of this elite. The alarming distrust of the news media isn’t rooted in inaccuracy or poor reportorial skills but in the daily conflict of world views between reporters and their readers.
This is an explosive situation for any industry, particularly a declining one. Here is a troubled business that keeps hiring employees whose attitudes vastly annoy the customers. Then it sponsors lots of symposiums (讨论会) and a credibility project devoted to wondering why customers are annoyed and fleeing in large numbers. But it never seems to get around to noticing the cultural and class prejudices that so many former buyers are complaining about. If it did, it would open up its diversity program, now focused narrowly on race and gender, and look for reporters who differ broadly by outlook, values, education, and class.

【推荐1】All parents have sky-high hopes for their children. We want them to be confident and content. What can parents do to help their kids grow up to lead happy lives? Experts advise:
Helping them find their talents. In order to succeed, children need to feel they’re good at something. So expose your children to as many interests as possible; then let them choose those they like best.
Applauding their achievements. A study found that students whose parents paid attention to their abilities were far more likely to do well in school—and in life—than students whose parents didn’t show such support. So celebrate your kids’ achievements, no matter how small they are.
Praising their efforts. Kids won’t always come out on top. Still, they deserve kudos for trying their best. Ten-year-old April Cutler, for example, has had trouble with math since the second grade. “She usually gets C’s on her report card, but last year she was determined to get A’s and worked hard at it, ” says her mom. “When the first grading period ended, April was disappointed when she got a B minus in math, ” Lueille continues. “But my husband and I told her we were very proud that she’d improved. That inspired her to try even harder. She got a B plus for the next period!”
Letting them make decisions and mistakes. Making his/her own decisions increases a child’s sense of control and builds his/her self-esteem. And allowing kids to make wrong decisions—so long as doing so won’t harm them—helps kids learn from their mistakes.
Encouraging them to solve their own problems. As they grow, children need practice in communicating, standing up for themselves and compromising. One of the best places to learn these skills is at home. So the next time your child runs to you complaining that her brother is blaming her, step back and let them work it out.

【推荐2】US enrollment(入学注册)of international students declined for the second year in a row, sending waves of unease across American colleges and universities, which see students from abroad as a buffer (缓冲) against the falling number of US high-school students graduating each year.
The number of new international students enrolling at American institutions fell by 6.6% during the 2017-18 academic year, while a 3.3% decline the year before, according to a report by the Institute of International Education (IIE). The total number of international students in the US plus those working here on a student visa rose by just 1.5% this year. That was down from average annual growth of 6.1% over the past decade. Several factors are driving the decrease. Visa and immigration policy changes by the Trump administration have prevented some international students from enrolling, college administrators and immigration analysts said. A strong dollar has made US college tuition relatively more expensive, Canadian and European universities are competing fiercely for the same students, and headlines about mass shootings also may have prevented some students, said Allan Goodman, president of IIE.
Foreign students are big business. They pumped $42 billion into US college and university coffers (金库) in the 2017-18 school year alone.

【推荐3】Teaching is not an easy career (职业) to go into, yet it’s one of the most important careers in a culture. The future of a country depends on the quality of education that its next generation (代) receives and the character that the children develop. Even though educators are the most important part of our schools, the structure (结构) of the education system in the United States is not set up to fully support them. In fact, it often puts them in difficult situations.
In most careers, salaries (工资) are based on education, experience, and performance. Not so with teaching. In many schools, teachers aren’t paid based on their level of education or experience. Though many go into the career because of their love of teaching and working with children, being fairly rewarded for their work is a problem.
Add to the fact that many teachers have to spend their summers making enough money to support their family, so many teachers are leaving the field. A 2019 study reported that about 8% of teachers gave up the career each year. The result will soon be that there won’t be enough educators.
One of the reasons why teachers are leaving the field is that they don’t get respect in the classroom. Disrespect, in my view, is the biggest problem that our teachers face and it has got worse in recent years.
How to improve this situation? Schools should take care of teachers in them, and our teachers need more of us to support them. They need us to raise our voices for a stronger education system that supports them. They should be offered better salaries and more chances of career improvement. These will encourage more people to be teachers.
