Going to school means learning new skills and facts in different subjects. Teachers teach and students learn, and many scientists are interested in finding ways to improve both teaching and learning processes.
Sian Beilock and Susan Leving, two psychologists at the University of Chicago, are trying to learn about learning. In a new study about the way kids learn math in elementary school, Beilock and Levine found a surprising relationship between what female teachers think and what female students learn: If a female teacher is uncomfortable with her own math skills, then her female students are more likely to believe that boys are better than girls at math. “If these girls keep getting math-anxious female teachers in later grades, it may create a snowball effect on their math achievement,” Levine told Science News. The study suggests that if these girls grow up believing that boys are better at math than girls are, then these girls may not do as well as they would have if they were more confident.
Just as students find certain subjects to be difficult, teachers can find certain subjects to be difficult to learn—and teach. The subject of math can be particularly difficult for everyone.
The new study involved 65 girls, 52 boys and 17 first-and second-grade teachers in elementary schools in the Midwest. The students took math achievement tests at the beginning and end of the school year, and the researchers compared the scores.
The researchers also gave the students tests to tell whether the students believed a math superstar had to be a boy. Then the researchers turned to the teachers: To find out which teachers were anxious about math, the researchers asked the teachers how they felt at times when they came across math, such as when reading a sales receipt. A teacher who got nervous looking at the numbers on a sales receipt, for example, was probably anxious about math.
Boys, on average, were unaffected by a teacher’s anxiety. On average, girls with math-anxious teachers scored lower on the end-of-the-year math tests than other girls in the study did. Plus, on the test showing whether someone thought a math superstar had to be a boy, 20 girls showed feeling that boys would be better at math—and all of these girls had been taught by female teachers with math anxiety.
According to surveys done before this one, college students who want to become elementary school teachers have the highest levels of anxiety about math. Plus, nine of every 10 elementary teachers are women, Levine said.

A new web standard is expected to kill passwords, meaning users will no longer have to remember difficult logins for each and every website or service they use.
The Web Authentication (WebAuthn) standard is designed to replace the password with biometrics and devices that users already own, such as a security key, a smartphone, a fingerprint scanner or webcam. Instead of having to remember an increasingly long string of characters, users can authenticate their login with their body or something they have in their possession, communicating directly with the website via Bluetooth, USB or NFC.
''WebAuthn will change the way that people access the Web, '' said Jeff Jaffe, chief executive of the World Wide Web Consortium (W3C), the body that controls web standards. One example of how WebAuthn will work is that when a user visits a site they want to log into, they input a user name and then get an alert on their smartphone. Tapping on the alert on their phone then logs them into the website without the need for a password.
WebAuthn promises to protect users against phishing attacks and the use of stolen credentials as there will be nothing to steal, the authentication token is generated and used once by their specific device each time the user logs in.
''After years of increasingly severe data breaches and password credential theft, now is the time for service providers to end their dependency on vulnerable passwords and one-time-passcodes and adopt phishing-resistant FIDO Authentication for all websites and applications, '' said Brett McDowell, executive director of the FIDO Alliance, one of the bodies pushing the new standard.
WebAuthn should also help people use unique login details for each and every service they use, instead of using the same login and password for every site, which many people still do, leaving them vulnerable to further attacks if one site is hacked.
The W3C has moved WebAuthn to what's called the ''candidate recommendation'' stage – the penultimate step before it becomes an approved web standard – inviting sites and services to begin implementing it. The web standards body announced that Google, Microsoft and Mozilla had committed to supporting WebAuthn, meaning that all major web browsers short of Apple's Safari will implement the new standard.
''While there are many web security problems and we can't fix them all, relying on passwords is one of the weakest links. With WebAuthn's multi-factor solutions we are eliminating this weak link, '' said Jaffe.
Several sites and services already use similar methods to log in, including Google and Facebook, which can both be logged into using a USB security key. But a single cross-platform, cross-service standard ratified by the W3C will mean that many more sites and services will be able to kill the password as the defacto login method.
WebAuthn is the culmination of many years of work and the change will not happen overnight. But as it increasingly seems inevitable that our email or other online services will get hacked into, removing the password is an important step in improving online security and making using sites and services easier.
1.What's the purpose of the new Web Authentication standard?
A.To create a way to login in place of the traditional password.
B.To help users to improve the way of inventing the password.
C.To make people visit a site much faster and more smoothly.
D.To inform readers of a new tool against phishing attacks.
2.What does the underlined part ''which many people still do'' mean in Paragraph 6?
A.They change their passwords when using a computer system.
B.They use the same login and password on different websites.
C.They copy information from the web in the same way as before.
D.They worry about being attacked while surfing the Internet.
3.According to Jaffe, web security problems ______.
A.have been solved completely at present
B.are often connected with hacking and phishing
C.will disappear one day with the WebAthn
D.may probably be casted by unsafe passwords
4.What can we infer from the last paragraph?
A.WebAuthn is the important product through longtime efforts.
B.WebAuthn will change people's way of using computer sooner or later.
C.Emails are safer ways for people to send and receive information.
D.Removing passwords will surely end the risks caused by hacking.

New rules for middle school students came out in March. Middle school is going to use a new way to decide who the top students are. The top students won’t only have high marks. They will also be kids who don’t dye(color)their hair, smoke or drink. The following are some of the new rules.
Tell the truth. Have you ever copied someone else’s work on an exam? Don’t do it again! That’s not something an honest student should do. If you have played computer games for two hours in your room, don’t tell your parents you have done homework.
Do more at school. Good students love animals and care for other people. April is Bird-Loving Month in China. Is your school doing anything to celebrate? You should join! That way, you can learn more about animals and how to protect them. When more people work together, it makes it more fun for everyone. Have you ever quarreled with your teammates when your basketball team lost? Only working together can make your team stronger. Be friendly to the people you are with. Try to think of others not only yourself.
Be open to new ideas. Have you ever thought that people could live on the moon? Maybe you’ll discover Earth II someday. Don’t look down on new ideas. Everyone’s ideas are important. You should welcome them, because new ideas make life better for everyone.
Protect yourself. Has someone ever taken money from one of your classmates? Don’t let it happen to you. If you have to go home late, you should let your parents know.
Use the Internet carefully. The Internet can be very useful for your studies. But some things on the Internet aren’t for kids, so try to look at Web pages that are good for you. You can use the Web for fun or homework.

Dear World:
My son starts school today. It's going to be strange and new to him for a while. And I wish you would sort of treat him gently.
You see, up to now, he's been king of the house. He's been boss of the backyard. I have always been around to repair his wounds, and to ease his feelings.
But now things are going to be different.
This morning, he's going to walk down the front steps, wave his hand and start on his great adventure that will probably include wars and tragedy and sorrow.
So, World, I wish you would sort of take him by his young hand and teach him the things he will have to know. Teach him but gently, if you can. Teach him the wonders of books. Give him quiet time to ponder(思考) the eternal mystery of birds in the sky, bees in the sun, and flowers on the green hill. Teach him it is far more honorable to fail than to cheat. Teach him to have faith in his own ideas, even if everyone else tells him they are wrong. Teach him to sell his physical strength and brains to the person who offers the most money, but never to put a price on his heart and soul. Teach him to close his ears to a criminal gang (团伙) ...and to stand and fight if he thinks he's right. Teach him gently, World, but don't coddle him, because only the test of fire makes fine steel.

Traveling to a new country isn’t as simple as just buying a ticket and boarding a plane. In fact, it can be easy for an awkward situation to occur. Different customs can often cause misunderstandings and even trouble. To help prevent a serious culture pas, an article in the Daily Mail highlighted taboos in certain countries. Let’s take a look.
France
When visiting France, you’d better not be caught cutting your lettuce with a knife and fork. It’s an insult to the chef and suggests that the salad hasn’t been prepared correctly. The correct way to eat lettuce in France is to fold it with your fork to make it fit in your mouth.
Italy
It’s actually best to be a little less friendly than usual when you visit Italy. It’s considered strange to make small talk with strangers, as the locals are reserved. Too much familiarity from a stranger can be seen as threatening, so keep greetings short.
Mexico
In Mexico, bringing an expensive gift to someone’s home is a no-no, as it could be seen as a tribe. Something simple like flowers and chocolates would be accepted. But you should avoid taking along marigolds (金盏花) or red flowers, because in Mexican culture, they symbolize death and can be associated with witchcraft(巫术).
Germany
You have to be careful with gifts of flowers in Germany too. Steer clear of carnations(康乃馨),as they are used for funerals. And an even number is considered unlucky. So if you want to give your host flowers, ask them what their favorite flowers are before your visit. And be sure to bring an odd number.
How to avoid 1.________ taboos in a new country
France | Taboo: Cutting your lettuce with a knife and fork. Reason: It’s an 2._______ to the chef, suggesting the salad has not been prepared correctly. Solution: 3.______ your lettuce with your fork to make it fit in your mouth. |
