In light of the technological route that education is on today there has been some speculation as to the role of teachers in future education. To what extent do you think teachers are being replaced by computers?
Information and Communication Technology (ICT) is quickly playing an important part in teaching in schools and other educational institutions. As more and more subjects can be taught via the computer, there would seem to be less and less need for teachers to be present, as self-study and autonomous learning are encouraged with the assistance of a computer. However, computers will never replace teachers because technology is only a tool and can never replace the spiritual element of the teacher.
Self-study and independent learning using technology is a means of teaching that can be highly effective for practice drills, the study of factual knowledge, or for pure rote memorization. For instance, computers can help students solve math exercises and memorize historic facts. This type of teaching reduces the need of the presence of a teacher. Online teaching or video conferencing allows a teacher to teach to a greater number of students, optimizing costs for schools. This is already happening at the university level where many universities are offering online degrees, for example. Such teaching is profitable to universities as it optimizes costs by increasing teacher-student ratios. I t would therefore seem that technology is making the teacher more and more redundant.
But a crucial element has to be considered with regards to ICT and teaching. Good teaching takes place when the learning is directly associated with our emotions. We learn best when what we are learning has a direct implication on what we believe and what we feel. The computer may communicate concrete knowledge, but only the teacher is able to communicate wisdom, to build self-confidence, and to make one think creatively, which is a more important part of learning. Therefore, no matter how sophisticated technology becomes, a teacher will always be needed, because only with the presence of the teacher is there true interaction.
What will happen is that technology will not replace teachers. Instead, teachers will no longer be able to teach students by rote memory or drill type exercises. The computer will take care of that. The teacher will have to stimulate the minds and bring out the creativity in his or her students. The teacher will have to become a better teacher, a real teacher. ICT will improve teaching, and force teachers to be better teachers; it will never replace the teacher, it will only make him or her more important.
2. The younger generation is up-to-date with new techniques and advances in science. They are often better able to make important decisions than their parents are. To what extent do you agree or disagree with this opinion?
The younger generation is up-to-date with new techniques and advances in science. They are often better able to make important decisions than their parents are. To what extent do you agree or disagree with this opinion?
The Net-Generation is here and whether we like it or not younger generations are in a position to be able to make significant decisions that will affect us all.
What causes this generation to be poles apart from its predecessors is not just its demographic force but that it is the first to mature surrounded by digital media. Computers can be found everywhere and digital technologies such as cameras, video games and DVDs are now commonplace. Increasingly these new media are linked by the Internet, and increasing web of networks which is attracting a million new users monthly, according to popular news sources. For today’s youngsters digital technology is no more frightening than a VCR or a vacuum cleaner.
For the first time in history children are more at ease, clued-up and literate than their parents about an innovation of innermost importance to society. I would argue that it is through this use of digital media that the N-Generation will develop and superimpose its culture on the rest of society.
Already the Net-Generation is defining itself as a reckonable force for social transformation. Unfortunately, few parents are aware of what their children are doing in cyberspace which intensifies the traditional norms associated with the generation gap. School officials are also struggling with the reality of students often being far more intelligent on cyber-issues and new ways of learning than their teachers. Likewise, corporations are trying to establish what these kids will be like as employees since they are used to very different ways of working, collaborating and creating and they discard many basic assumptions of today’s companies.
I believe that there is no single issue more imperative than understanding what the Net-Generation intends to do with its digital expertise. There is a lot we can find out about a whole generation, which is in the process of taking on new media, from the children who are most adept in their adoption of this technology.
3. Many are of the opinion that the Internet is inundating our children with dangerous information. There is however no doubt that the Internet represents great advances in communication and the dissemination of information. Discuss the pros and cons of the Internet and present your opinion on this matter.
Many are of the opinion that the Internet is inundating our children with dangerous information. There is however no doubt that the Internet represents great advances in communication and the dissemination of information. Discuss the pros and cons of the Internet and present your opinion on this matter.
Bearing in mind the likely effects of the Internet on today’s users is important, because it is an issue that is discussed daily nowadays by people in both the private and public sectors. It is an everyday occurrence to come across articles in newspapers and there has been a visible boom in websites devoted to the trend. I would like to argue that the importance of this topic, regarding the pros and cons of the Internet, lies somewhere in the broader framework of questions raised by the Internet debate.
The Internet as the name suggests is a complex net of computer. Conversely, it might be more useful to think of the Internet as a network of people who make use of computers. A significant feature of the Internet is that it offers more ways to communicate than any medium in the past; thereby enabling users a variety of ways to retrieve information from the same computerized network system.
It is widely accepted by most that education is something that most, if not all people come into contact with at one point or another in their lives. This contact occurs typically and to the greatest degree at an early age. The principle role of schools is to educate people about their nation and the wider world, and also to help prepare them for the job market. The problem of unemployment is a commonly recognized fact. If schools are indeed doing their best to prepare young people for the job market, then their national curriculum needs to reflect the skills considered necessary for the most popular work sectors.
Depending on its use, the Internet may or may not contribute to the development of key skills related to critical thinking, group work, and problem solving. Over the course of time, I believe children will most likely adopt a different and possibly greater responsibility as learners when using the Internet.
As we are all aware, there is more information offered on the World Wide Web than anyone could possibly need and most of this information is very easily reached. Therefore, students have to act responsibly when choosing what information to use. The risk of being distracted while using the Internet is always there; however, even if young learners do browse off every now and then, they are still using the most hi-tech interactive tool we have in education for today’s world.
4. Spending money on scientific research should only be approved when there are economic benefits resulting form the research. To what extent do you agree or disagree with this opinion?
Spending money on scientific research should only be approved when there are economic benefits resulting form the research. To what extent do you agree or disagree with this opinion?
A primary challenge for developing and post-industrial societies is not only to garner enough funding for scientific research but to go further in their spending for development if they want to secure positions as truly knowledge-based economies. An appreciation for investing in scientific research has matured steadily in recent decades. Having said this however, most would agree that it is not easy to gauge the direct social and economic benefits resulting from scientific research. Many of the features of our modern world are the direct results of scientific research. Computers are but one area that receives a staggering amount of investment as countries compete with one another for stakes in this lucrative market. Medical research, likewise, is well worth the investment that is made for finding new ways to ensure the well-being of those fortunate enough to be able to receive treatment. These are but a few obvious examples.
However, what is almost certain is that in many cases the time from scientific discovery to the commercialization of research results may often be long. However, there are many instances of breakthroughs in research that provide additional support for the popular principle that public investment in basic science generates continued economic and social benefits.
The evidence presented in research journals available to the public confirms that government-funded research is a vital source of investment for increasing a society’s knowledge and skills. When governments invest in scientific research their funding in trun expands the technological opportunities available to companies who wish to develop new products and processes. Such spending on scientific research also supports the education of students who in turn transfer their competencies in science and technology into the private commercial sector.
Due to the widespread understanding that the development of economically viable research projects is often a lengthy and time-consuming process it is natural that some people would be opposed to the idea of further government money being spent on scientific research. However, I believe the rewards from research and development are well worth waiting for in this ever changing world of ours.
5. Although many benefits may result from space exploration, the costs involved are enormous. There is some debate as to whether this money could be more wisely spent to provide for the basic needs of mankind such as food, clean water, contraception etc. For this reason space exploration should be restricted. What is your opinion?
Although many benefits may result from space exploration, the costs involved are enormous. There is some debate as to whether this money could be more wisely spent to provide for the basic needs of mankind such as food, clean water, contraception etc. For this reason space exploration should be restricted. What is your opinion?
One giant step forward for mankind: there were the words of American astronaut, Neil Armstrong, the first man to land on the moon.
Space exploration is considered by most developed countries and those aspiring to compete in the race for development as the last frontier known to mankind. However, there are many people who belong to nations which have space programs who question the expenditure involved in continued space exploration when it is apparent that money is needed to deal with many of the world’s existing problems, for example, pandemic situations like AIDS and poverty that are always on the increase.
A trip to the moon was an incredible success in 1969; however we have plainly taken a step backwards in the last 30 years or so. The dreams of travel to outer lying planets like Mars and Pluto remain as distant as ever, not forgetting the dream of interstellar voyages and exploring new solar systems. A big part of the problem is that our current technology is simply unable to realize these dreams. Even our best chemical rocket would take somewhere between one and two years to reach the closer planets and this is largely due to the fact that before reaching the desired destinations rocket fuel is likely to run out.
The amount of money required to fuel space exploration programs of such large proportions begs the question of just how feasible all this spending is. It is clearly prohibitively high and a key objective for the years ahead will be to lower the cost to a fraction of today’s value. In the meantime however, we need to realistically face the problems existing on our earth which are far more pressing and far more concerned with true development.
Making dreams come true on this planet, of a better world for everyone to live in, is surely more achievable for mankind than reaching outer lying galaxies which are light years beyond our existing capabilities.
6. Technology is making it possible to stay at home and work. Discuss the advantages and disadvantages of this and present your opinion on this issue.
Technology is making it possible to stay at home and work. Discuss the advantages and disadvantages of this and present your opinion on this issue.
There is a revolution going on in the developed world whereby the work-from-home dream is becoming more and more of a reality for millions of workers wishing to save time, see their families more, and achieve overall work-life equilibrium. This is made possible for many by advances in information and communications technology, namely with the advent of the Internet and mobile telecommunications such as broadband phone connections.
In the following paragraphs I will examine both the potential benefits and downsides of this new phenomenon which allows high-speed transmission of data from your personal computer at home to your clients and work colleagues in different locales.
It is true that computers these days have greater processing power than they did just a few years ago, but working from home is not just an issue of cost-saving. People are tired of commuting and the time spent on trains and subways is a precious commodity that could be spent more effectively on work. In many cases working from home is not actually a choice for most business executives who are accountable for business transactions around the clock.
For those people with young children, working from home has many incentives. Indeed, one could argue that a lot of flexi-working has evolved around parents’ child-rearing responsibilities. However, those parents who are working from home are now experiencing new pressures in the work-from-home setting. In spite of the paybacks from less travel and more flexibility, there is downside with increased working hours. The reality is that all home workers with children feel that balancing home and work responsibilities is easier said than done.
To make one final point, it is important when considering this growing trend in working from home that we do not see it as an easy option.
7. With the development of modern science and technology, some aspects of traditional culture are being lost, and some people now believe that traditional cultures will eventually be replaced by modern science and technology such as computers and the Internet.
With the development of modern science and technology, some aspects of traditional culture being lost, and some people now believe that traditional cultures will eventually be replaced by modern science and technology such as computers and the Internet. What is your opinion on this matter?
Digital information technologies are symbolic of the dominant global culture that is currently taking our world by storm. Due to developments in modern science and technology, traditional ways of earning a living, learning something new and even that of existing are rapidly transforming. This transformation in the way we communicate and live is as significant as the invention of writing which altered the course of ancient cultures before us.
Nevertheless, up-to-the-minute technologies have the capacity to preserve many aspects of traditional culture. Indeed, if we are to employ information and communications technologies effectively, traditional values and ethics can help us make decisions for the proper use of these new technologies, In this essay I will explore how the negative impact of the Internet on traditional cultures and values can be lessened through awareness-raising exchanges and education.
In most parts of the world governments authorities reacted to the introduction of the World Wide Web by prohibiting unlimited access to all Internet sites. They argued that some content found on the Internet would jeopardize traditional cultural and religious values. In the last few years, however, although this issue is still hotly debated among the powers that be, we are now seeing bans lifted on Internet access in all corners of the world.
The Internet is changing traditional cultures by offering users new means for voicing their opinions about everything, including politics, religion, and love. For example, in the United Arab Emirates where the two sexes are firmly segregated, the Internet is enabling men and women to communicate in new ways that were not permissible before. Additionally, as a communications medium the Internet is allowing traditional values to be heard alongside more unconventional values as users face up to different ideas and hear other people’s opinions.
The networking and awareness-raising potential offered by computers and the Internet about different cultures and values is unlimited. Now that we have people from more traditional cultures communicating online it is almost assured that their values and beliefs will be more readily heard and respected by the all-encompassing global Internet community.
8. Does modern technology make life more convenient, or was life better when technology was simpler? What is your opinion?
Does modern technology make life more convenient, or was life better when technology was simpler? What is your opinion?
It is difficult to think how we managed our lives before the widespread use of everyday technologies such as the Internet and mobile phones which we now take for granted. Despite this, how often do we stop to question ourselves, before going online to check our email accounts, whether modern technology has really made our lives more convenient? Some people may actually answer to the contrary, that modern technology has made their lives more complicated and even more difficult.
The obvious advantages of modern-day technologies are many. For example, if I do not want to go home and wash my laundry and wait for the weather to clear so I can hang it outside to dry, I simply invest in a machine that can both wash and dry my clothes. In addition, I would feel safer in the knowledge that because my clothes are not hanging up outside the possibility of them being stolen is greatly reduced.
Inventors throughout the ages have thought of practically every device imaginable to assist humans in conducting their everyday affairs, from baby strollers to life-support machines. In fact, we are inundated with technological contraptions in this modern world and there is no sign of a reversal in this trend occurring.
Imagine for a moment, if there were no television or computers. How would you know who had won the latest soccer match? Or what was going on in the news? What would the weather be like tomorrow? The problem with modern technology is not the unlimited choices in gadgetry now made available to us; but instead, it is our increasing inability to tune out from an overload in information and our growing reliance on machines that perform midless taskes which we could simply do for ourselves.
The use of modern technology does inspire inventors, designers and engineers to speculate on what technology will be like in the future and how it could further mankind’s survival and development. However, before we turn around and say technology is the best thing that ever happened to us, it is vital that we remember who is in control of technology in order for it not to take over our lives completely.
9. Modern technology has had a great influence on people’s entertainment choices, making them less creative. To what extent do you agree or disagree with this opinion?
Modern technology has had a great influence on people’s entertainment choices, making them less creative. To what extent do you agree or disagree with this opinion?
There exist many different types of entertainment technologies which cause us to behave in a variety of ways. Television, for example, only requires passive viewing and listening and can be looked upon as a form of entertainment which dulls the mind. The Internet, on the other hand, requires users to be interactive through the employment of, for example, different motoring skills i.e. clicking, selecting text etc. , to more challenging tasks such as searching, emailing, chatting, and the uploading/downloading of software. A lot of people are still choosing television as their preferred entertainment for relaxing after a hard day’s work, but even more people are getting excited about the on-line world as they discover what it can do for them.
The irony of this essay question is that without creativity we could not have the modern technology that we use today. We would not have television or the Internet. Similarly, we would not have MP3 players or DVDs. Every invention known to mankind has always resulted from creative thinking. Arguably, creativity is our most important asset; and information is an inestimable tool. With no electronic databases, PCs, and other supportive networking technology, we would be hard pressed to organize all of our information efficiently and effectively.
However, if we examine the example of the Internet closer, we can also discern that the quantity of information on-line is escalating at a staggering rate. This means that it is difficult for individuals to remain up-to-date in their chosen fields. This means that it is difficult for individuals to remain up-to-date in their chosen fields. Due to this increasing pressure in the working world, it is therefore necessary for people to band together, to work collaboratively, and to think creatively and imaginatively to thrive and even to survive.
In conclusion, I would like to add that the days of choosing modern technology purely for entertainment purposes are diminishing. It is no longer enough to merely own modern gadgetry. Instead, you must be able to show that you can manipulate technology creatively to suit your every purpose.
10. What differentiates one country from another is becoming increasingly difficult to define in today’s world. Nowadays, it is not uncommon for people to have the same consumer products and to experience the same media the world over. To what extent do the advantages outweigh the disadvantages?
What differentiates one country from another is becoming increasingly difficult to define in today’s world. Nowadays, it is not uncommon for people to have the same consumer products and to experience the same media the world over. To what extent do the advantages outweigh the disadvantages?
Globalization certainly has the potential to bring about great advances for humankind. On a daily basis, we are eyewitnesses to how borders of time and space that once separated countries and the activities therein appear to be diminishing.
In industrialized areas of the developing world we can observe a growing international trend in leisure time pursuits. Chinese youths wearing Nike sneakers in Shanghai hang out in Starbucks over a cup of coffee in much the same way that their American counterparts do in New York. In particular, younger generations the world over who can afford access to media technologies like cable television and the Internet often encounter the same media such as advertisements, films, TV channels, popular brands and so on.
However, it is not presently guaranteed that these advances are equally shared by all members of the global community. The truth lies somewhere closer to the fact that global market forces often have negative effects on the distribution of public goods such as social, a clean environment, or diverse cultural expression.
Many argue that the costs of globalization are too high and that differences between countries and communities need to be maintained before we quickly and completely lose all sense of who we are, where we came from and what choices are still available to us.
Therefore, it is necessary for the global community to place greater emphasis on the impact of globalization on human welfare. In order to achieve a just and equal distribution of the benefits of economic globalization, its negative side effects need to be counteracted by reforms in government at the international, regional and local levels. Only by further developing the way in which we manage our societies can we make sure that those currently not in control of globalization can make their voices heard in the political processes affecting the range of their own personal choices.
11. Technology can bring many benefits, but it can also cause social and environmental problems In relation to new technology, the primary duty of governments should be to focus on potential problems, rather than benefits. Please discuss the issues raised here and offer your opinion.
Technology can bring many benefits, but it can also cause social and environmental problems In relation to new technology, the primary duty of governments should be to focus on potential problems, rather than benefits. Please discuss the issues raised here and offer your opinion.
It is true that new technologies can create serious social and environmental problems. The question is whether governments should focus on these problems when they are formulating policies related to new technology.
Some people would argue that governments have an important watchdog role to play and that they should attempt to establish whether a proposed technology is likely to have any harmful effects. This is seen as an aspect of government looking after public interests and showing concern for the welfare of its citizens. These are the same people who have invested the government with the power to veto the introduction of certain technologies.
The problem with this approach, however, is that it is very difficult to know in advance what the full effects of any new technology will be. The history of science and technology has many fascinating examples of unexpected developments. Sometimes a technological advance in one area can lead to a surprising breakthrough in another, seemingly unrelated area. For example, technology which originated from the US space program has been further developed and applied in many other areas of life. And one certainly cannot depend on government bureaucracies to make accurate assessments about these matters.
Another problem is that, where one government might decide to ban the use of a new technology, another country may well go ahead with its introduction. In an increasingly competitive global economy, the first country may severely disadvantage itself by such inaction.
New technology is essential for a country’s economic development. The best approach is to positively encourage the development of new technologies and to focus on their benefits. Any problems that may arise can be dealt with after implementation.
