Recently,people in US education have gotten extremely worried because a new report has shown that American students have a math problem.

    The 2015 Program for International Student Assessment（评估）(PISA) shows math scores in the US getting lower and no improvement in science or reading.PISA tests 15-year-olds from different countries and regions in their math,science and reading skills.About 540,000 students from 72 countries and regions took part in the assessment in 2015.

    US scores in reading and science were about the same as three years ago,leaving Americans near the middle of the bigger group.But the situation in math is much more worrying.The US average score was 470,be;ow the OECD（经合组织）test average of 490,meaning the US was No.40 among the 72 countries and areas.It was 12 points lower than in 2012 and 18 points lower than in 2009.So,what is going on with American students' math skills?

    One reason may be that the US does not teach math in enough depth."Students are often good at answering the first part of a problem in the United States,"said Andreas Schleicher,director of education and skills at OECD."But as soon as students have to go deeper and answer the more complicated part of a problem,they have difficulties."In comparison,many high-performing countries and regions in math teach a lot less but focus in much greater depth, especially when you look at East Asia,Japan and Singapore,according to Schleicher.

    Another reason may be the fact that many people in the US are unwilling to travel to foreign countries to learn better teaching practices."One of our biggest challenges in the US is that the teachers are not going out and seeing what high-performing countries do differently,"said Wendy Kopp,who started Teach for America,in a news program.

    Leadership today is not about forcing others to do things. If this is even possible, it is short-term. If you order someone to do something against their will, they may do it because they feel they must, but the anger they feel will do more harm in the long-term. They will also experience fear.

    Fear causes the thinking brain to shut down, making the person unable to function at his or her best. If they connect you with this emotion of fear, they will become less functional around you, and you will have succeeded in not only shooting yourself in the foot, but possibly making a very good employee or partner unable to perform effectively. Fear has no place in leadership.

    The way we affect people in a lasting way is by our own character, and our understanding and use of emotion. We can order someone to do something, which may be part of the work day, or we can employ them at the emotional level, so they become fully devoted to the projects and provide some of their own motivation（积极性）.

    Today's work place is all about relationships. Anyone works harder in a positive environment in which they're recognized and valued as a human being as well as a worker. Everyone produces just a bit more for someone they like. Leaders understand the way things work. They know money is not the only most motivating factor in the work life of most people.

    The true strength of leadership is an inner strength that comes from the confidence of Emotional Intelligence-knowing your own emotions, and how to deal with them and those of others. Developing your emotional intelligence is the best thing you can do if you want to develop your relationships with people around you, which is the key to the leadership skills.

    About one in ten video game players shows signs of addictive behavior that could have negative effects on their family, friends and school work, according to a new study conducted in New York.

    Researchers at Iowa State University(ISU) and the National Institute on Media and the Family found that some gamers show at least six symptoms of gambling addiction such as lying to family and friends about how much they play games, using the games to escape their problems and becoming restless when they stop playing.

    They may also skip homework to play video games or spend too much time playing games and do poorly in school. "While the medical community currently does not recognize video game addiction as mental disorder, hopefully this study will be one of many that allow us to have an educated conversation on the positive and negative effects of video games," said Dr. Douglas Gentile, an assistant professor of psychology at ISU.

    Dr. David Walsh, the president of the National Institute on Media and the Family which tries to reduce the harm of media on the health and development of children and families, said the findings are a wake-up call." This study gives everyone a better idea of the problem," he explained.

    The researchers, who studied 1,178 American children and teenagers, aged 8 to 18, found some displayed at least 6 of 11 symptoms of pathological (病态的) gambling as stated by the American Psychiatric Association. Addicted gamers played video games 24 hours a week, twice as much as casual gamers. Some addicted gamers even steal to support their habit, according to the findings that will be published in the journal Psychological Science.

    While video games can be fun and entertaining, some kids are getting trouble. "I continue to hear from families who are concerned about their kids' gaming habits. Not only do we need to focus on identifying the problem, but we need to find ways to help families prevent and treat gaming addiction.

    One day, on a small farm in Maine, a man sat in a barn watching a large grey spider spin a web. The man was E.B. White — or Andy, as he was called — who thought spiders were wonderful creatures. He thought that one day he might like to write a children's book about a spider.

    But writing was hard work for Andy. He had written many articles and essays and poems. He had also written one children's book, Stuart Little. But Andy could never just rush to turn an idea into an article or a book. He told his editor (编辑) that he needed to let his ideas ripen.

    So for years, Andy continued to think about writing a children's book about a spider. He did some of his best thinking while he wandered around his farm.

    Once while he was cleaning his barn, he found a spider's egg sac (卵囊). Andy wanted to see the eggs hatch. But he was scheduled to leave for a trip to New York City. So he found a small box and carefully placed the egg sacinside. When he got to his hotel, he put the box on the dresser. One morning he woke up, and there were hundreds of baby spiders rushing across the dresser!

    Years later, Andy finally began writing Charlotte's Web, the story of a spider named Charlotte and a pig named Wilbur. Andy created most of the book sitting by himself in the tiny boathouse of his farm.

    Sometimes he stopped writing and aimlessly drew pictures of spiders. Andy always said Charlotte's Web was more than just a children's story about animals. It was a timeless story about true friendship.

    When I was growing up, we were not an "I love you" family. We certainly found such affection lovely. We just didn't do it.

    I was thinking about all of this on Saturday at my daughter Katie's recital (演奏会). I had never insisted she do anything in her free time except learn how to play the piano. I carried this from childhood. My parents couldn't afford these lessons. My daughter mostly accepted this demand with good humor. This has meant, through the years, that our house has been filled with a few muddled (混乱的) complaints mixed with versions of songs.

    The day of the recital, I was listening to Katie practice The Entertainer, and one note was not good. I don't know how to play the piano, but I did say, "Hey, Katie, maybe you should hold that note just a bit longer." Then she played it again and again. I realized that I had done something unintended — I was making her think too much just a few hours before her recital.

    So I told her not to worry about it, but it was too late. She kept at it for a little while longer until finally I said that she'd played it perfectly. I didn't think we ever isolated that note; I felt pretty bad for even bringing it up.

    Then it was time for recital. Katie was the first one to perform. She was dressed well. As I watched her play The Entertainer, all I could think was how grown-up she had become, and that I had already missed the four-, five-, six-year-old versions of her.

    She got to the end of the song, and she reached the note we had talked about. And she held it. She held it so long that for an instant it broke her timing on the rest of the song. Then she finished the song, and she looked right at me. Then I hugged her. My parents are right. You don't have to say the words "I love you". Sometimes one note will do.
