A business school in Paris will soon begin using artificial intelligence and facial analysis to determine whether students are paying attention in class. The software, called Nestr, is used in two online classes at the ESG business school beginning in September.
The idea, according to LCA founder Marcel Saucet, is to use the data that Nestor collects to improve the performance both students and professors. The software uses students' webcams(网络摄像头)to analyze eye movements and facial expressions and determine whether students are paying attention to a video lecture. Professors would also be able to identify moments when students' attention declined, which could help to improve their teaching.
Advocates for AI in education say the technology could be used as a digital tutor that would adapt to a student's individual needs, and help develop more effective studying habits. Such software could also help teachers by providing quantitative(定量的)feedback on the effectiveness of their teaching.
But AI programs rely on massive information of personal data. and there are concerns over how such data would be treated. Saucet says Nestor won't store any of the video footage(片段)it captures and that his company has no plans to sell any other data the software collects. In addition, some are concerned that AI may one day replace teachers.
Rose Luckin, a professor at the University College London Knowledge Lab, says AI could unlock the "black box of learning" by providing information on how and when learning happens. But she cautions(告诫)against adopting new technologies that, while alluring, may not actually respond to critical needs. She thinks a program like Nestor could be useful for students who take classes remotely, since "there isn’t a human there watching them". So Luckin sees the technology more as an assistant, rather than a replacement.
Sauce agrees. "Human contact is not going to go away, " he says. "There will always be professors."

Chloe Kim was one of America's top Olympians during last year's Winter Games in Pyeongchang, South Korea. The snowboarding champion, who grew up in California, competed there at 17 years of age. She became the youngest woman ever to win an Olympic gold medal in the halfpipe competition.
She has recently won a halfpipe competition during the Winter X Games in Aspen, Colorado. But the 18-year-old snowboarder has decided to trade some trips down the halfpipe for an Ivy League education after an upcoming world championship competition in Utah. Beginning from next fall, Kim will be joining Princeton University's class. Instead of centering on the physics of her winning snow board moves, she could now be learning the subject in school. In a recent interview, Kim said, “While I have a special identity and my life has always been so different, I still aim to make my higher education experience as normal as possible.” Kim added, “I'd love to be Chloe, the girl who sits next to me in English class.”
Kim received widespread attention during the Pyeongchang Games. The publicity was fueled by her friendly, energetic nature as well as her interesting family story. Along her path to Olympic gold, Kim also became a social media star. She helped design a snowboarding Barbie doll in her likeness, rapped with hip-hop artist G-Eazy and joined other sports stars to be honored with ESPY Awards. While all of this was fun, Kim says she now looks forward to a new challenge—earning a degree from one of America's top universities. She says she considers her acceptance to Princeton just as much of an honor as earning an Olympic gold medal.
She is still deciding what her exact field of study will be at Princeton. But she says it will involve something science-related, possibly chemistry or biology. She is attempting to work out a plan that will permit her to keep training while going to classes. Kim says her sports and educational goals go hand-in-hand. “It's all about progressing the sport and also pushing myself,” she said. “To see what can do, and how far I can go.”

When my three boys were young, our summer vacation consisted of driving the nine hours to my parents' place in Maine, where I grew up. While we loved those visits, the truth is we couldn't afford to go anywhere else. My husband, David, and I had finally saved up enough to buy our first home. We'd even made an agreement: We wouldn't spend more than $ 100 without consulting each other.
On one of those holidays, I took the boys to the local library, where a silent auction was underway. I was attracted by one item: Shot nearby, on the rocky coast, the photo was naturalistic, capturing the characteristic of the young subjects and the beauty of my home state. Up for bid: a session with the photographer.
In a hurry, I wrote down my name on the sign-up sheet, half sure that my offer of $ 500 would be topped. It wasn't. And though I felt bad about breaking my agreement with David, I was happy with my bid won.
The morning of the shoot, we put the kids into the car and drove to a favorite beach. The photographer, already standing in the parking lot with a camera around her neck, started snapping pictures the minute they got out of their car seats. She gently tried to persuade the boys forward, leading them to gather around a rock pool.
When the contact sheet arrived, I knew it had been worth the money. In the photos each boy's personality shone clearly.
More than a dozen years later, the portrait is a touchstone for me, a key to understanding who my children are. The photograph is a piece of art and a piece of our family history, worth every penny.
