The Pew Internet Project did the survey with the National Writing Project. Judy Buchanan is the vice director of the National Writing Project and a co-author of the report. Ms. Buchanan says digital research tools are helping students learn more and faster. “Teachers really favor these tools because they are ways to make some of the learning exciting and engaging. Young people favor these tools. The goal is to really help them become creators of meaningful content, and not just sort of consumers.”

    But one problem the survey found is that many students lack digital literacy. They trust too much of the information they find on the Internet. Judy says these students haven't developed the skills to determine the quality of online information.“It's something that really has to be taught and paid attention to. Because in a world in which things happen quickly, you do need to step back, reflect and analyze the information you have.”

    Another problem is blamed on something that might not seem like a problem at all: being able to quickly find information online. Teachers say the result is a reduction in the desire and ability of their students to work hard to find answers. They say students are overly dependent on search engines and do not make enough use of printed books or research libraries.

    Many teachers are also concerned that the Internet makes it easy for students to copy work done by others instead of using their own abilities.

    Two heads are better than one. It means that two people working together have a better chance of solving a problem than one person alone. But not everyone likes working in a group.

    There can be a number of reasons why people dislike group work. Some may feel nervous or uneasy in group situations. Others might have had a bad experience with individuals who did not work well as a team. Another comment is that teachers or instructors fail to provide roles for group members. This may create a situation where everyone or no one wants to lead. Whatever the issue, the result is the same: the group does not realize its goal.

    Cooperative (合作的) learning is an educational method that can help to solve this problem. There are many methods of cooperative learning. Today we will talk about one: giving each person in a small group a specific duty to reach a shared goal. For example, if learners are divided into groups of four people each, their roles might be: leader, writer, checker and speaker. This structure helps ensure that everyone takes part equally in group work and allows each member to play a meaningful part in completing the shared goal.

    Before dividing learners into groups, it is a good idea for the teacher or club's instructor to first have knowledge about the language skill levels of participants. The goal is to make each group a mixture of higher- and lower-level language learners. Putting too many people with similar skill levels together could make the work too difficult or easy. Role cards can be a helpful tool in this method of cooperative learning. Their purpose is to remind learners of each person's role.

    Before the cooperative activity, the role of the teacher or activity instructor is to explain two things to the group: the main job for the activity and how the cooperative roles work. The person in charge may appoint these roles or let the English learners choose them. Then, during the activity, the instructor's job is to watch the groups and provide more guidance when needed. After the activity, the instructor may wish to provide feedback to groups on their work and their use of cooperation.

    With this cooperative learning method, you can say that four heads are better than just one.

    Andrew Jackson has been sitting pretty on the $20 bill for 87 years. Is it time to bring some new blood to the banknote?

    The non-profit organization called Women on 20s is campaigning to put a woman's face on American money. Barbara Ortiz Howard, the company's founder, would like to see a woman on the $20 bill by 2020.That year marks the 100-year anniversary of the 19th Amendment to the United States Constitution, which gave women the right to vote.

    Howard got the idea when she realized that her daughter had no everyday reminders of famous women in history. She asked her friend Susan Ades Stone, a journalist, to join her cause. “Part of the aim is to educate as many people as possible about as many women as possible,” Ades says. “We want to see how many people we can reach.”

    American money values the successes of former presidents and founding fathers. Currently, there are only two women on money: Susan B. Anthony is the face of the rare dollar coin, and Sacagawea can be seen on the gold dollar coin. There are no women on paper bills.

    With help from writers and historians, Howard and Stone came up with a voting list featuring 15 important women. Ades says there is a standard for choosing candidates. They look at the women's contributions to our world, and at what challenges they faced.

    More than 72,000 people have voted so far in the poll. Ades says the competition has narrowed to a “very close race”, but won't say who's in the lead. After two rounds of voting, Women on 20s will send their campaign to the White House for consideration. The final decision is up to the Treasury Secretary, Jack Lew. Lew is unlikely to make a change without the president's approval. But last year, when a little girl asked the president why there aren't any women on US currency, he said that adding a woman is a “pretty good idea”.

    Unbelievable Stories of Animals Acting Just Like Humans

    Horses are picky eaters

    Horses have an even better sense of smell than humans do. When horses raise their noses and open their nostrils (鼻孔) , their nervous system allows them to sense smells we can't sense. This might explain why they refuse dirty water and carefully move around meadows, eating only the tastiest grasses, experts say.

    Whale says thanks

    In 2011, a whale expert spotted a humpback whale trapped in a fishing net and spent an hour freeing it. Afterward, in an hour-long display of thanks, the whale swam near their boat and leaped into the air about 40 times.

    Pandas like to be naughty

    Is there anything more lovely than a baby panda, except maybe a human baby? In fact, baby pandas sometimes behave like human babies. They sleep in the same positions and value their thumbs. Pandas are shy by nature for its shy behaviors such as covering its face with a paw of ducking its head when confronted by a stranger.

    A cat honors its owner

    Paper towels, and a plastic cup are just a few of the gifts that Toldo, a devoted three-year-old gray-and-white cat, has placed on his former owner Iozzelli Renzo's grave every day since the man died in September 2011. Renzo adopted Toldo from a shelter when the cat was three months old, and the two formed an inseparable bond. After Renzo passed away, Toldo followed the coffin to the cemetery, and now "stands guard" at the grave for hours at a time.

    It's fun to dream about vacationing in Europe, but international flights are not always particularly affordable. If you're looking to experience a taste of European culture, however, there are many places in the US with a European heritage (传统).

    Founded by Spanish settlers in 1565, St. Augustine is full of Spanish-inspired architecture, historical sites and other attractions. The Colonial Quarter is a popular tourist area, and there are many places to grab traditional Spanish food.

    Holland, Michigan

    Holland was settled in 1847 by Dutch Calvinist separatists, under the leadership of Dr Albertus van Raalte. Terrible economic conditions in the Netherlands forced them to emigrate (移居国外), while their desires for religious freedom led them to unite and settle together as a group. Much of the original architecture was destroyed in an 1871 fire, but the city still has many windmills, eateries, art and even an annual tulip festival and holiday market.

    New Glarus, Wisconsin

    More than 160 years after it was founded, New Glarus has maintained much of its Swiss heritage and old world traditions. New Glarus' Swiss immigrant roots are proudly on display with its Alpine architecture, Swiss Historical Village Museum and Yodel Club. The Wisconsin village also puts on cultural events like the Heidi Folk Festival and Swiss Volksfest.

    Solvang, California

    Located near Santa Barbara, Solang is a charming California city with Danish roots.  A group of immigrates from Denmark founded Solvang just over 100 years ago to create a Danish home away from home. As such, the city is full of Danish architecture, restaurants, shops and even a copy of Copenhagen's famous Little Mermaid statue.
