In a class this past December,after I wrote some directions on the board for students about their final examination,one young woman quickly took a picture of the board using her smart phone.When I looked in her direction,she apologized:"Sorry.Was it wrong to take a picture?"

    “I can't read my own handwriting,”the young woman explained."It's best if I take a picture of your writing so I can understand the notes."

    That remark started a class-wide conversation about taking a picture instead of taking notes.For those in the photo-taking camp,motivations extended beyond their inability to comprehend their own handwriting.Some took pictures of notes because they knew their phone was a safe place to store material.They might lose paper,but they wouldn't lose their phones.Some took photos because they wanted to record exactly the manner in which I had noted information on the board.Others told me that during class they liked to listen to the discussion attentively.

    Yet the use of cameras as note takers,though it may be convenient,does raise significant questions for the classroom.Is a picture an effective replacement for the process of note-taking?

    Instructors encourage students to take notes because the act of doing so is more than merely recording necessary information—it helps prepare the way for understanding.Encouraging students to take notes may be an old-fashioned instructional method,but that a method has a long history doesn't mean it's out of date.Writing things down engages a student's brain in listening,visual,and kinesthetic learning—a view supported by a longstanding research.The act of writing down information enables a person to begin committing it to memory,and to process and combine it,establishing the building blocks of learning new concepts.

    Taking a picture does indeed record the information,but it deletes some of the necessary mental engagement that taking notes employs.So can the two be equally effective?

    I'm not sure how to measure the effectiveness of either method.For now,I allow students to take notes however they see fit—handwritten or photographed—because I figure that some notes,no matter the method of note-taking, are better than none.

    I grew up in a troubled home in the 1970s, on the outskirts of downtown Orlando, Florida. Not far away, a three-story house attracted my eyes.

    It was nothing like the one I lived in with my mother, a small dark place with rules about befriending others. “Don't. Never, ever talk to anyone,” my mother said.

    One day, in sixth grade, a black-haired woman was introduced to our class: Mrs. Reese. Reese explained that she was starting Spanish Club. She invited anyone interested in learning Spanish language and culture to stay after school.

    I could not take my eyes off her bracelets(手镯) and shining rings. The bell rang, and to my shock, no one went up to Mrs. Reese. I was under strict orders to go straight home. But that day, I stayed. I asked Mrs. Reese when the club started.

    “We could begin right now if you like,” she said with a smile. I felt beautiful. That day I learned that the house of my dreams was her house. I learned how to answer questions about my age and my favorite food in Spanish. And I learned, “Do you want to come over tomorrow for cooking lessons?”

    I wanted to say “Yes”, but Mom's words held me back.

I begged my mother all summer and into fall, well after Spanish Club had dissolved. I wept at night sometimes, so worried that Mrs. Reese and her family would move away.

    At some point, I managed to wear my mother down and one Saturday afternoon. I rode out to Mrs. Reese's house.

    The details of that afternoon are marked in my mind: We had tea. She painted my toenails red. We made a garlicky picadillo. We spoke in Spanish. In Spanish, my voice was loud and romantic. This is the real me! I remember thinking.

    My mother never permitted me another visit to Mrs. Reese's house. But four decades later, I still remember that day and the life she showed me, proof of a possible future.

    Last week, about 600 teenagers in the US imagined a future changed by technology in which their lessons are taught by robots and they learn about celebrities and alien languages. They believe they will use jet packs, and hoverboards (旋转飞盘), as everyday transport.

    All the participants (参加者) of the survey are teenagers born into the Internet age. The study is to show how the first cyber (与电脑有关的) generation dream about a future life created by advanced technology.

    Most believe there will still be schools to go to, but that technology will play an increasingly important role in learning. The 600 teens surveyed think there will still be teachers, but 37 percent imagine them to be robots. Some 24 percent believe that teachers will still be human but they will have interchangeable microchips (微型芯片) so that one person can teach all subjects.

    More than one in two believe hoverboarding will be popular, while one-third say that wearing rocket boots will be their favourite activity. Another third think jet packs will be popular. Nearly 30 percent think football and bike-riding will remain popular.

    When it comes to the courses, they think future generations will be learning about robot building (63 percent), alien languages (47 percent), celebrities (26 percent) and R&B music (22 percent).

Children will wear virtual reality helmets (可视头盔) to bring lessons to life, say 40 percent, while over 20 percent believe they will not need lessons because microchips put in their head will send relevant (相关的) information into the brain.

    Matt Whyman, adviser to the chief medical officer on youth issues at American Online, said, “The kids seem very aware of the liberating qualities of technology.”

    Samuel Morse was born in Massachusetts USA. He started off his career as an inventor after being a painter and sculptor (雕塑家). He even earned a gold medal from the famous Adelphi Society of Arts for his first effort in sculpture, the "Dying Hercules". He became the first president of the National Academy of Design, and was made Professor of the Arts of Design in the University of the City of New York.

    Yet, this painter turned to inventing to make his fortune during a sea voyage. On this journey, Samuel Morse heard about many attempts to create usable telegraphs. He was fascinated by this problem and began to study books on physics for two years to gain more scientific knowledge. He realized that pulses (脉冲) of electrical current could carry information over wires.

    Thus the world's first working model of a telegraph was born. His signaling device was quite simple. It consisted of a transmitter (containing a battery and a key), a small buzzer (蜂鸣器) as a receiver and a pair of wires connecting the two. Samuel Morse improved it by adding a switch and a second buzzer to allow transmission (传播) in the opposite direction as well.

    On May 24, 1844 Samuel Morse sent the first electronic message between Baltimore and Washington, "Look what God has enabled us to build, and benefit by."

    Seventeen years later, the two coasts of the United States were linked by telegraph. The telegraph continued to enjoy the position of being the fastest and most reliable means of communication for almost 140 years since its invention.
