    Students perform better when their instructors use hand gestures—a simple teaching tool that could generate benefits in higher-level math such as algebra(代数).

    A study published in Child Development,the top-ranked educational psychology journal,provides some of the strongest evidence yet that gesturing may have a unique effect on learning.Teachers in the United States tend to use gestures less than teachers in other countries.

     "Gesturing can be a very beneficial tool that is completely free and easily employed in classrooms," said Kimberly Fenn,study co-author and assistant professor of psychology at Michigan State University."And I think it can have long-lasting effects."

    Fenn and Ryan Duffy of MSU and Susan Cook of the University of Iowa conducted an experiment with 184 second-,third- and fourth-graders in Michigan elementary classrooms.

    Half of the students were shown videos of an instructor teaching math problems using only speech.The others were shown videos of the instructor teaching the same problems using both speech and gestures.In the speech-only videos,the instructor simply explains the problem.In the other videos,the instructor uses two hand gestures while speaking,using different hands to refer to the two sides of the equation.Students who learned from the gesture videos performed better on a test given immediately afterward than those who learned from the speech-only video.

    Another test was given 24 hours later,and the gesture students actually showed improvement in their performance while the speech-only students did not.

    While previous research has shown the benefits of gestures in a one-on-one tutoring-style environment,the new study is the first to test the role of gestures in equivalence learning in a regular classroom.

    The study also is the first to show that gestures can help students transfer learning to new contexts—such as transferring the knowledge learned in an addition-based equation to a multiplication-based equation.

    Fenn noted that U.S.students lag behind those in many other Western countries in math and have a particularly hard time mastering equivalence problems in early grades."So if we can help them grasp this foundational knowledge earlier," she said,"it will help them as they learn algebra and higher levels of mathematics."

(1)、Which of the following can be the best title for the passage?

A、How to Learn Higher-level Math Well B、Simple Teaching Tools Used in Math Learning C、Teachers' Gestures Boost Math Learning D、Why U.S. Students Can't Learn Math Well
(2)、Researchers explain their opinion in the educational psychology journal by ________.

A、setting down general rules B、using a great many examples C、making questionnaire survey D、presenting research findings
(3)、What do you know about the experiment conducted by Kimberly Fenn?

A、The experiment was done with 184 students of the same age in elementary classrooms. B、The students were divided into two groups and got different teaching methods. C、Researchers drew the conclusion based on the only one test they did in the experiment. D、Researchers had not done any research on the benefits of gestures before this one.

One day when I was 12, my mother gave me an order: I was to walk to the public library, and borrow at least one book for the summer. This was one more weapon for her to defeat my strange problem — inability to read.

In the library, I found my way into the “Children's Room.” I sat down on the floor and pulled a few books off the shelf at random. The cover of a book caught my eye. It presented a picture of a beagle. I had recently had a beagle, the first and only animal companion I ever had as a child. He was my secret sharer, but one morning, he was gone, given away to someone who had the space and the money to care for him. I never forgot my beagle.

       There on the book's cover was a beagle which looked identical(相同的) to my dog. I ran my fingers over the picture of the dog on the cover. My eyes ran across the title, Amos, the Beagle with a Plan. Unknowingly, I had read the title. Without opening the book, I borrowed it from the library for the summer.

Under the shade of a bush, I started to read about Amos. I read very, very slowly with difficulty. Though pages were turned slowly, I got the main idea of the story about a dog who, like mine, had been separated from his family and who finally found his way back home. That dog was my dog, and I was the little boy in the book. At the end of the story, my mind continued the final scene of reunion, on and on, until my own lost dog and I were, in my mind, running together.

       My mother's call returned me to the real world. I suddenly realized something: I had read a book, and I had loved reading that book. Everyone knew I could not read. But I had read it. Books could be incredibly wonderful and I was going to read them.

       I never told my mother about my “miraculous” (奇迹般地) experience that summer, but she saw a slow but remarkable improvement in my classroom performance during the next year. And years later, she was proud that her son had read thousands of books, was awarded a PhD in literature, and authored his own books, articles, poetry and fiction. The power of the words has held.

    It is widely acknowledged that it is by no means an easy task to bring up a child well. And our ancestors already understood it well. As an old proverb says, “It takes an entire village to raise a child.” That is being quoted more and more often these days. And I'm pleased about that.

    Parents need to be involved in their children's education in many ways. Helping children with homework and studying, going on a field trip, teaching a craft or coaching a child's sports team are all great ways to be involved with your child's education. And don't forget to communicate with teachers—they need and respect your input. Studies show that children learn more and schools function better when parents and schools work together.

    Communities can help children create and achieve new goals. There are other ways such as helping with homework. reading to a child, coaching a children's team, providing emotional support, helping solve problems and building self-esteem(自尊). Kids need role models and advisers can be role models by sharing their experiences and wisdom.

    Businesses can also help shape our children's future—invite a class from your local school to visit your workplace. You may be providing a glimpse that opens a new world of possibilities. Show students what goes on during a typical day. Give a mini course for students: how products are made; how machinery works. You may have a developing electrician, a teacher, a nurse, or even a newspaper reporter on your hands.

    It really does lake an entire village to raise a child. So share the responsibility-and the joy—of bringing a child to his or her full potential.

    Many of us just laugh it away when they are told incredible (难以置信的) stories about other people, but I have a deep interest in these stories and I prefer to believe they are true. Here's one I collected from a total stranger.

    "Well, I was 11 when my family arrived at Fern Lake overlooking Trail Ridge Road in Rocky Mountain National Park. It was so beautiful to look miles across the Rockies and thousands of feet below into the valley. My parents were busy getting lunch out of the trunk so I climbed over the wooden fence to get closer to the cliff edge in the hope that I wouldn't miss any beautiful sight down there.

    I started down a little hill but soon started sliding on loose pebble rocks(鹅卵石). I fell on my back, but kept going faster and faster to what seemed the edge of the world (a 2,000 foot drop). In seconds I knew I was going to die. My feet and legs went first over the edge at a high speed. Then suddenly I felt two hands push hard on my chest and stopped me dead. My heart was racing and I slowly inched my body back to where I finally could make it back up the hill.

    My father was waiting there and screaming at me for doing such a dangerous stunt (特技). I tried to tell him and my mom about the hands that held me back, but to this day they don't believe me. They thought I was just trying to get out of trouble with a made-up story.”

    We parted ways, but I assured her that I believed every word of her story. I could see a little surprise and happiness on her face.

    That's why I always ask people to share their miracles (奇迹). Each real story makes my days full of hope and gratefulness.
