Technology in education
词(副词)

观点
Over the last several decades, large investments have been made to equip primary and secondary schools with computers and teacher training. Now it is time to examine whether there has been a sufficient return on this investment. Does technology really offer substantive(真的,实际的) advantages to students? Does technology accelerate or impede real progress in education? Similarly, does technology serve as a teaching crutch(帮助教学的东西) or does it offer the ability to promote sustainable change(一定的变化) in the world’s classrooms? And if so, is the technology deployed(有效地使用) today being used to best possible advantage? What conditions need to exist in schools for technology to have an impact? (ISSUE开头可用)

The opening statements for and against the motion give some ground for agreement, and much ground for argument.
Both of our speakers, I deduce, are persuadable that technology could in principle be a vital source of advancement in learning-if only it was to be implemented with enough brilliance and resources. But is even this true? I would be pleased to hear from commenters who believe that education is primarily a matter of character building, and, as such, an activity best conducted among human beings, with the least possible mediation. Will any of our grandchildren look back on his or her schooldays, and credit his or her success in life to "a really good computer"?
反方1:Is there an argument for keeping new technology out of the classroom, precisely because it is so ubiquitous everywhere else already? Can a child who is chatting online or video-gaming for six hours every day really benefit from spending even more time staring at a screen in the classroom?
How do we even measure-and how broadly should we measure-the educational impact of new technologies? No doubt, by putting iPods in the classroom, we can improve iPod skills. No doubt a newer generation of microprocessors can help the maths class calculate pi to even more decimal places. But what about social skills? Kindness? Common sense? Happiness? Physical fitness? Latin and Greek? Do those go into the metrics公制长度单位)米的, 以米为基础的?(观点1:这些现代科技虽然提高了人们的某些技能例如算术等,但同时也损害了人的社会性,可用来分析科技对人的影响并不总是积极的)
All of this, moreover, assumes that resources are plentiful. But what about school districts with very limited budgets, or education ministries in poorer countries? (观点2:对某些不发达国家,这套理论是不适用的)Should they see technology as a way to cut the cost of delivering education? Or as an expensive add-on to basic teaching methods? We are in danger of encouraging them to take the first approach, only to discover that new technologies are all too often disastrously(灾难地) complicated and expensive to implement-as we find often enough in other areas of government and industry.
Finally, for now, let us remember that we are talking here about new technologies. Their application is, by definition, a matter of experiment. Do we want to experiment with our children's education? Do you want someone experimenting on your children? Perhaps you do, and perhaps you should, since only by experimenting can we ever make progress. But if you prefer educational methods tried and tested over centuries, please say so. Likewise(同样地,照样地), if you feel it would be barmy(愚蠢的,疯狂的) to exclude from education technologies(拒绝…进入…) that are commonplace elsewhere in life, please say so too. These are both defensible-and assailable(可辨的且易受攻击的)-positions.(观点3:从公民的常识和意愿出发,阐明技术在教育上的不适用性)

观点:
1.综述科技的利弊;
2.这套理论如果应用在不发达国家,则会产生荒谬的结果;
3.即使客观条件允许,从公民的主观意愿出发,这个也行不通。
反方2:Technology has transformed everyday life in much of the world. Goods that were once the preserve of the rich are now household items. Food is abundant and varied. Travel has been transformed. News and entertainment come to us instantly from around the world. Technology and the media have transformed all aspects of human life - except education!(观点1:开门见山)(ISSUE开头可用)
Politicians still campaign for 'education, education, education', lamenting(痛恨,遗憾) the poor performance of their schools.(教育在各国糟糕的表现) America, the earliest country to be infatuated(使热恋) with computers in the classroom, gets mediocre(平庸的) outputs from its school system by international standards. Most poor countries struggle to reach the Millennium Development Goal of universal primary education. For them universal secondary access is a distant dream. Meanwhile rich countries worry about boys dropping-out of school.
Technology is replacing scarcity by abundance in other aspects of life: why not in education?(过渡段)
It is not for lack of prophets(先知). Ever since the invention of the blackboard each new communications medium has been hailed(如雨后春笋般发生) as an educational revolution. Rosy forecasts about the impact of radio, film, television, programmed learning, computers and the Internet succeeded each other through the 20th century although, revealingly, each prophet compared the revolutionary potential of the newest medium to the printing press, not to the previous technological white hope!
Why hasn't it worked? Why has the continuing introduction of new technologies and new media added little to the quality of most education? What can we learn from those few applications of communications media that are acknowledged successes?
Technology is the application of scientific and other organized knowledge to practical tasks by organizations consisting of people and machines(technology定义). In "The Wealth of Nations" Adam Smith described how applying knowledge to the practical task of making pins led to a factory that produced them with consistent quality in higher volume and at lower cost than artisans(工匠) making each pin by hand. The technological bases of Adam Smith's pin factory were the principles of specialisation, division of labour and economies of scale.(观点2:对科技重新下了定义,提出了亚当斯密效率最优的原则)可用来分析科技的影响
Most applications of technology in education disappoint because they ignore these principles and so fail to use technology's intrinsic(固有的,内在的) strengths to tackle real problems. What are the practical tasks that challenge education?
In my work at UNESCO and the Commonwealth of Learning I spend many hours with ministers of education; sometimes individually, sometimes in groups at international meetings. The practical task facing ministers of education is to expand access to quality education as economically as possible. They want the same outcomes as Adam Smith's pin factory: higher volume, consistent quality, lower cost.
This is the great opportunity for technology in education. Tinkering(胡乱地改进) with traditional classroom teaching cannot achieve these three outcomes because improving any one outcome makes the others worse(观点4传统的教育方式不能使得效率最优). Increasing volume with larger classes lowers quality. Enhancing quality with more learning materials raises costs, and so on.
Successful ways of introducing technology and media to education tackle this challenge head on(直接的): cutting costs, increasing volume and assuring quality all at the same time.
The best examples are the open universities. The UK Open University has created a multi-media learning system that enrols(使入学) 200,000 students annually(每年), operates at a lower cost than other UK universities, and ranks 5th, just above Oxford University, on aggregate ratings of teaching quality. In a quite different context India's Indira Gandhi National Open University enrols 1.5 million students and places 17th in the latest web ranking of universities on the sub-continent.
The secret of the open universities' success is twofold(双重的). First, they tackle real problems, in this case scaling up(扩大) educational provision and taking it to people who cannot access conventional teaching. Second they combine people and technology, using the principles of specialisation, division of labour, and economies of scale, to create new learning systems that are scaleable at low cost with consistent quality.
The tragedy, and why you must vote for the motion, is that these successes are rare.(观点5:之所以反对,是因为成功的案例太少了) Most attempts to introduce media into education do not take advantage of technology's strengths. Instead, they continue in the tradition of education as a cottage industry(小农产业), hoping to make it more effective by providing the individual artisan, the classroom teacher, with fancier tools.
This approach is doomed to(注定) failure. It increases costs because the technology is simply an add-on. The number of learners remains essentially unchanged. Quality goes down because few teachers know how to use the new tools effectively and the students, who often do know how to use them, would rather apply them to other tasks.(从老师和学生的对比来说明)
Having devoted much of my life to promoting the effective use of technology in education it saddens me that I have to support this motion because there are still so few examples of its effective deployment. I only hope that your passing the motion will be a wake-up call to educators and make them reflect seriously on why their use of technology has been such a disappointment. I suggest three reasons.(开始提出原因)
First, we assume too often that technology is the answer without asking what the question was.(我们需关心的是要解决的问题是什么,而不仅仅只看到答案) Successful applications begin with a clear and difficult problem to solve instead of a vague assumption that technology will enhance teaching.
Second, we usually focus on improving existing teaching systems whereas technology is better used to create new learning systems. (科技的有效利用必须配合体制的改革)Enjoining all teachers to become artisans of eLearning is not going to improve educational outcomes.
Third, there is the quest(寻求) for the magic medium, the ultimate technology that will revolutionise education. Yesterday it was the Internet; today it is Open Educational Resources. But there is no magic medium and never will be. Each technology has its strengths. The task is to use them to create a world where education of quality is abundantly available.(我们应该学会的是如何有效地应用科技,而不是把改革教育的希望寄托在新技术的发明上)
We are still a long way from that goal. To pretend otherwise is to sell technology far too short. So far, and I say it with regret,the continuing introduction of new technologies and new media has added little to the quality of most education.
观点:
1.举出实例来说明教育的严峻状况;
2.提出教育对科技应用失败的原因是没有遵循效率最优的原则;
3.举出两个正面例子来说明科技的好处;
4.但由于不具有普遍性,所以不能说明科技对教育有帮助;
5.分析原因,主要从技术虽然是新的,但体制的僵化导致无效率这个角度阐述;
6.再从3个角度分析科技对教育没起到作用的原因
