Schools in the US and elsewhere are announcing bans on the recently released AI — powered ChatGPT out of fear that students could use the technology to complete their assignments. However, bans may be practically impossible given how difficult it is to detect when text is composed by ChatGPT. Is it instead time to rethink how students are taught and evaluated?

Educators are starting to question what it means to assess student learning if an AI can write an essay or paper similar to, or even better than, a student would — and the teacher can’t tell the difference. Many teachers believe the time-honored learning tradition will be destroyed from the ground up by Chat GPT. The Los Angeles Unified School District in California first blocked the use of ChatGPT on networks and devices in December 2022.

However, removing technology from the classroom can mean undesirable consequences, such as creating more obstacles for students with disabilities, says Trust. Additionally, restricting the use of ChatGPT on school networks and devices can’t stop students from using ChatGPT at home and in libraries.

It is also unclear if anti-cheating software can reliably detect AI-assisted writing. OpenAI is working to develop a digital watermark that can help teachers and academics spot students who are using ChatGPT to write essays. Open AI’s attempts to watermark AI text, however, hit limits.

Instead of worrying about how ChatGPT could enable cheating, educators should ask what motivates students to cheat in the first place and work on developing relationships of trust, says Jesse Stommel at the University of Denver in Colorado.

“Talk to students really frankly about what ChatGPT’s capable of, what it’s not,” says Stommel. “Have students use it to write an essay about Jane Austen and gender dynamics, and then have them read that essay and peer review it and think about what ChatGPT gets right and wrong.”

Most of us know what it’s like to get presents. Whether it’s for a birthday or other celebration, it’s hard to beat the excitement of opening a carefully wrapped box to find something that’s both unexpected and suits you perfectly. Now, imagine if you could get the same feeling when you go shopping for yourself. That’s the feeling that mystery boxes hope to reach.

Mystery boxes are not a new idea—they were a feature of department stores in Japan in the early 20th Century. They contain different products sold at a lower price than their combined value. The key thing is that customers don’t know what’s in the box before they buy. All kinds of mystery boxes are available: fashion boxes, food boxes, beauty boxes, even loot boxes, which are virtual items for video games.

The pleasant surprise is not the only attraction of mystery boxes. They also allow people to try things that they otherwise wouldn’t. Seasonal vegetable subscription(订购)boxes might lead people to learn to cook new meals. They can also potentially offer great savings—as the recommended selling price of the contents is often far higher than the purchase price. For sellers and suppliers, the benefits are clear- it allows them to sell unwanted things for a profit. British fashion mystery box businessman Mario Maher highlights how mystery boxes can help reduce the amount of waste in the fashion industry. People might discover product ranges that would otherwise be thrown away.

There is an obvious disadvantage to mystery boxes -when you buy them, you don’t know what you’ll get! It may be that the goods inside are not to your taste, but there is also the potential for cheats to use the unpredictability of mystery boxes to send items that have a much lower value than the price of the box.

So, are mystery boxes a fun way of reducing waste and making shopping more exciting, or more an opportunity for disappointment, or worse—tricks?

As night falls on the streets of Shanghai, Mikiko Chen can often be found pacing up and down through the winding narrow streets of the city hunting for discarded items.

“I pick up all sorts of things, chairs, wine boxes, bowls and cups. . . it’s like treasure hunting for me, “she says. The 27-year-old digital marketer is among the first adopters of “stooping” in China, a practice that refers to picking up discarded furniture and other goods on the streets for re-use. She says the concept “stooping” was inspired by New Yorkers who often leave unwanted things on the “stoops” —or doorsteps—leading up to the entrances of buildings.

“The core concept of stooping for me is to make the best use of things,” Ms. Chen says. “It can help you to save money, but it’s not just about lowering consumption.” “It’s wasteful to throw away something that’s still usable; it’s better to share it with others who need it.”

Ms. Chen says she was among the first to use the hashtag (话题标签) #stooping on Xiaohongshu. “I initially started with posting items that people no longer used and wanted to throw away or exchange . . gradually I’m receiving hundreds of messages each day,” she says. Since then, the trend has become increasingly popular.

Ms. Chen says she is “very surprised” the concept has become a hit on social media, as older generations often stigmatize picking up things from the street or using second-hand goods. “People like my mum consider stooping as ‘rubbish picking’ and ‘scavenging’ (拾荒),” she says. “She thinks that people will look down on you for doing this.”

For Nan Zheng, an environmentalist and advocate, stooping is more than the physical act of picking up things from the streets. He created an app called “Grecycle” where people can give away or take unwanted items for free. “I think we can let more people know about the concept of stooping as an interesting and fun thing to do,” Mr. Nan says. “But then, gradually we can let people know this can also be about charity and helping others.”
