Teachers say the digital age has had a good influence and a not-so-good influence on this generation of American teenagers. More than 2,000 middle and high school teachers took an online survey. Researchers also spoke with teachers in focus groups.
Three-quarters of the teachers said the Internet and digital search tools have had a "mostly positive" effect on their students research habits and skills. But 87 percent agreed that these technologies are creating an "easily distracted generation with short attention spans (持续时间) " .And 64 percent said the technologies "do more to distract students than to help them academically(学业上) " . Many students think "doing research" now means just doing a quick search on Google.
The Pew Internet Project did the survey with the College Board and the. National Writing Project. Most of the teachers came from Advanced Placement classes, which provide college-level work for high school students.
Judy Buchanan is 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 learn faster. Teachers really welcome these tools because they are ways to make some of learning exciting and engaging.Young people welcome these tools. And the goal is to really help them become creators of content,and meaningful content, and not just sort of consumers.
But one problem the survey found is that many students are lacking in digital literacy. In other words, they trust too much of the information they find on the Internet. Another problem the survey found is blamed on something that might not seem like a problem at all: being able toquickly 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 depending too much on search engines and do not makeenough use of printed books or 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.

Every year, millions of people head to London's Trafalgar Square to see Nelson's Column,and the four Iion statues that “guard” it. And last month, during the London Design Festival, a bright red lion sculpture was added to the collection.
But this was more than just a statue: It had a large open mouth, with an LED screen inside it.At the same time, passersby could type in random words on a screen close to the lion, which were used to produce an AI-created poem. The most interesting part of the poems lies in their randomness, as the words that people choose to enter include many things, such as the time, the weather and their mood. Ín the daytime, the finished poem appeared on the LED screen, but at night, it was projected (投射) onto the lion's body and the famous Nelson’s Column, in a 1ovely light display.
Es Devlin, the sculpture's creator, was inspired by the history behind the four historic lion statues. Edwin Landseer, the designer of the lions, wanted them to look much more animạted, but Queen Vietoria refused his plan. This made Devlin wonder, "What if we could give a lion a poetic voice?". According to Devlin, althọugh England has seen many poems about national identity in recent years, these works have been lacking imagination. "I wanted to make a piece that was poetic and collective" he told BBC News.
Afier standing for almost 180 years, the purpose of Trafalgar Square has changed over the years. But thanks to the high-tech lion and its poetry, the square is standing the test of time.
