School leaders from around the country gathered at the White House on November 19 for"Connected to the Future," a conference about digital technology in education.Connected is the Obama Government's five-year plan to support the growth of digital learning in schools.This growth includes equipping America's schools with high-speed broadband Internet . At the conference,President Barack Obama said the U.S.Department of Education is taking steps to help educators and school districts as they change to digital learning.The department created new guidelines to help schools work to improve their technological infrastructure .The guidelines are also designed to help schools choose the right digital devices and set up policies for their proper use. "We have to do more to offer our children a world-class education,"Obama told the crowd of school leaders."We have to improve our education level if we are going to make sure that every child in America can go as far as their dreams and talents will take them." According to Cecilia Muoz,director of the Domestic Policy Council,less than 40% of public schools in America have high-speed Internet access in their classrooms.She believes that Connected will make America a leader in using technology to educate students.

At the end of the president's speech,1,200 school leaders attending the event signed the Future Ready District Pledge on their iPads.It promises the education leaders to help develop a culture of learning through technology at their schools,and to support teachers and students in using technology.

Wearing ties was originally the mark of Britain's most powerful classes, which made the tie itself a symbol of power and respect. And that led it to be adopted by a much larger tribe--the business tribe. You cannot wear a tie if you work with machinery. So wearing a tie became a sign that you were a man who used your brain to make a living, rather than your hands. It showed you were serious. It showed you were a professional. It meant that everyone who wanted a job in business had to wear one. It was just impossible to take seriously a man who didn't wear a piece of color1ed silk around his neck. This is how millions of people came to be wearing ties across the world. They are part of the uniform of business. "Ties offer a point of indifference," says John Milne, head of the British Guide of Tie Makers. "They give a chance to say something about their own personality." So if you happen to meet a man with a very brightly color1ed tie, there is a good chance that he is the office joker. There is also a good chance that he will be wearing brightly color1ed socks. Is there a future for ties? The signs are not promising. Tie wearing seems to be rare among the new bread of entrepreneurs in the Internet and new technology industries. Many political leaders,including British Prime Minister Tony Blair, now go without ties. This shows they are men of the people--but not the people wearing ties. Up until around 1960, it was common for men across the Western world to wear hats as part of their business uniform. That changed with the election of John F. Kennedy to the presidency of the United States. Kennedy never wore a hat in fact his nickname was"hatless Jack". Seeing that the most powerful man in the world did not have to wear a hat, millions of other men decided that they did not have to, either. Hats simply vanished across the Western world. Perhaps"tieless Tony"(UK Prime Minister Tony Blair) will have the same effect as "hatless Jack". In the business world,wearing a tie was necessary because _ . A) it showed you were a brainworker B) it showed you got a good salary C) it showed you were an employer D) it showed you were welltrained

Bad news sells. If it bleeds, it leads. No news is good news, and good news is no news. Those are the classic rules for the evening broadcasts and the morning papers. But now that information is being spread and monitored in different ways, researchers are discovering new rules. By tracking people's e-mails and online posts, scientists have found that good news can spread faster and farther than disasters and sob stories. "The 'if it bleeds' rule works for mass media", says Jonah Berger, a scholar at the University of Pennsylvania. "They want your eyeballs and don't care how you're feeling. But when you share a story with your friends, you care a lot more how they react. You don't want them to think of you as a Debbie Downer." Researchers analyzing word-of-mouth communication--e-mails, Web posts and reviews, face-to-face conversations--found that it tended to be more positive than negative, but that didn't necessarily mean people preferred positive news. Was positive news shared more often simply because people experienced more good things than bad things? To test for that possibility, Dr. Berger looked at how people spread a particular set of news stories on The New York Times' website. He and a Penn colleague analyzed the "most e-mailed" list for six months. One of his first findings was that articles in the science section were much more likely to make the list than non-science articles. He found that science amazed Times' readers and made them want to share this positive feeling with others. Readers also tended to share articles that were exciting or funny, or that inspired negative feelings like anger or anxiety, but not articles that left them merely sad. They needed to be aroused one way or the other, and they preferred good news to bad. The more positive an article, the more likely it was to be shared, as Dr. Berger explains in his new book, "Contagious: Why Things Catch On." Which tended to be most e-mailed according to Dr. Berger's research? A) Sports news. B) Science articles. C) Personal accounts. D) Financial reviews.
