Students and Technology in the Classroom

    I love my blackberry—it's my little connection to the larger world that can go anywhere with me.I also love my laptop computer,as it holds all of my writing and thoughts.Despite this love of technology,I know that there are times when I need to move away from these devices（设备）and truly communicate with others.

    On occasion,I teach a course called History Matters for a group of higher education managers.My goals for the class include a full discussion of historical themes and ideas.Because I want students to thoroughly study the material and exchange their ideas with each other in the classroom,I have a rule—no laptop,iPads,phones,etc.When students were told my rule in advance of the class,some of them were not happy.

    Most students assume that my reasons for this rule include unpleasant experiences in the past with students misusing technology.There's a bit of truth to that.Some students assume that I am anti-technology.There's no truth in that at all.I love technology and try to keep up with it so I can relate to my students.

The real reason why I ask students to leave technology at the door is that I think there are very few places in which we can have deep conversions（转变）and truly engage complex ideas.Interruptions by technology often break concentration and allow for too much dependence on outside information for ideas.I want students to dig deep within themselves for inspiration and ideas.I want them to push each other to think differently and make connections between the course,the material and the class discussion.

    I've been teaching my history class in this way for many years and the evaluations reflect student satisfaction with the environment that I create.Students realize that with deep conversation and challenge,they learn at a level that helps them keep the course material beyond the classroom.

    I'm not saying that I won't ever change my mind about technology use in my history class,but until I hear a really good reason for the change,I'm sticking to my plan.A few hours of technology-free dialogue is just too sweet to give up.

    Don't you hate it when someone snubs（冷落）you by looking at their phone instead of paying  attention? The word “Phubbing”, which comes from “phone” and “snub”, describes such behavior. With popularization of smart phones, we see a new "Phubbing" group everywhere in public places: in subway, restaurants, roads, people are checking the mobile phone, ignoring the people around completely. What is worrying us is that not only young people, but also the elderly and kids are getting addicted（上瘾）to Phubbing.

    On Dec 29th, a 28-year-old woman—a mother of two in Wenzhou, drowned after she fell into a river while looking at her mobile phone. A Pakistani man was killed on Dec 15th, 2015, after being hit by a fast moving train while trying to take a selfie (自拍)with it on the track. Last month, Justin, a college student was shot in subway in San Francisco, the U.S. The surveillance(监控)video showed that before Justin was killed, the killer pulled out the gun several times, and even wiped his nose with it. However, nobody noticed that. The surrounding passengers all focused on their cell phones.

    Phone is the tool for communication, but now it distances people and makes them separated from each other. Therefore, someone jokes “the furthest distance in the world is not the distance between life and death, but that you don't know I stand in front of you while you focus on the mobile.”

    Phubbing appears harmless; however, it does affect our life. 23-year-old Alex from Melbourne wrote in his blog: "I can no longer focus on what I am eating since I started twittering. My skill of food photography has improved very fast, while my interest in food drops a lot as a result."

    As traditional Chinese art, paper cutting has a long history. The first and earliest paper cutting was found in China 1,500 years ago. But this traditional art is at risk of disappearing now. Luckily, Vivian Woo, a Chinese immigrant in America, is trying to bring this art back to life.

    One Saturday in 2017，Ms. Woo held a paper cutting show at a shopping center near Washington. She got much fun and peace doing it. She hoped more people would enjoy it. Ms. Woo began to study the art of paper cutting as a 14 - year - old girl in her hometown in China. She said all the students at school had to learn paper cutting. But she had a deep love for it. So her teacher spent more time teaching her after class. Later, she won the second prize in a national painting and art competition. Ms. Woo went to America after she finished college in 2008. Soon after that, she took part in an activity to promote Chinese paper cutting. And then she was invited to show the art in many important activities. “It is important to promote this art to Americans or anyone who is interested in it. Maybe it will make this art more popular.” Woo said.

From the art of paper cutting, people can know about Chinese cultural values, history and stories of people's life. Ms. Woo uses the art as a tool to show Chinese culture to people who know little about it. Chinese art is not only for Chinese, but also for people ail over the world.

    Would it surprise you to learn that, like animals, trees communicate with each other and pass on their wealth to the next generation?

    UBC Professor Simard explains how trees are much more complex than most of us ever imagined. Although Charles Darwin thought that trees are competing for survival of the fittest, Simard shows just how wrong he was. In fact, the opposite is true: trees survive through their co-operation and support, passing around necessary nutrition (营养) “depending on who needs it”.

    Nitrogen (氮) and carbon are shared through miles of underground fungi (真菌) networks, making sure that all trees in the forest ecological system give and receive just the right amount to keep them all healthy. This hidden system works in a very similar way to the networks of neurons (神经元) in our brains, and when one tree is destroyed, it affects all.

    Simard talks about “mother trees”, usually the largest and oldest plants on which all other trees depend. She explains how dying trees pass on the wealth to the next generation, transporting important minerals to young trees so they may continue to grow. When humans cut down “mother trees” with no awareness of these highly complex “tree societies” or the networks on which they feed, we are reducing the chances of survival for the whole forest.

    “We didn't take any notice of it.” Simard says sadly. “Dying trees move nutrition into the young trees before dying, but we never give them chance.” If we could put across the message to the forestry industry, we could make a huge difference towards our environmental protection efforts for the future.

    Most young people enjoy some forms of physical activity. It may be walking, cycling, or swimming, or in winter, skating or skiing. It may be a game of some forms—football, basketball, hockey, golf or tennis. It may be mountaineering.

    Those who have a passion of climbing high and difficult mountains are often looked upon with astonishment. Why are men and women willing to suffer cold and hardship, and to take risks in high mountains? This astonishment is caused, probably, by the difference between mountaineering and other forms of activity to which men give their leisure.

    Mountaineering is a sport and not a game. There are no man-made rules, as there are for such games as golf and football. There are, of course, rules of different kinds which would be dangerous to ignore, but it is this freedom from man-made rules that makes mountaineering attractive to many people. Those who climb mountains are free to use their own methods.

    If we compare mountaineering with other more familiar sports we might think that one big difference is that mountaineering is not a “team game”. We should be mistaken in this. There are, it is true, no “matches” between “teams” of climbers, but when climbers are on a rock face linked by a rope on which their lives may depend, there is obviously teamwork.

    The mountain climber knows that he may have to fight forces that are stronger and more powerful than man. He has to fight the forces of nature. His sport requires high mental and physical qualities.

    A mountain climber continues to improve his skills year by year. A skier is probably past his best by the age of thirty. But it is not unusual for men of fifty or sixty to climb the highest mountains in the Alps. They may take more time than younger men, but they perhaps climb with more skills and less waste of effort, and they certainly experience equal enjoyment.
