As computers are being used more and more in education, there will be soon no role for teachers in the classroom.

There have been immense advances in technology in most aspects of people's lives, especially in the field of education. Nowadays, an increasing number of students rely on computers to research for information and to produce a perfect paper for school purposes. Others have decided to leave the original way of learning to get knowledge through online schools. These changes in the learning process have brought a special concern regarding the possible decrease of importance of teachers in the classroom.

Some people believe the role of teachers started to fade because computers have been helping some students to progress in their studies quicker than when compared with an original classroom. For example, in the same classroom, students have different intellectual capacities, thus some would be tied to a slow advance in their studies because of others’ incapacity of understanding. In this way, pupils could progress in their acquisition of knowledge at their own pace using computers instead of learning from teachers.

However, the presence of a teacher is essential for students because the human contact influences them in positive ways. Firstly, students realize that they are not dealing with a machine but with a human being who deserves attention and respect. They also learn the importance of studying in group and respect other students, which helps them to improve their social skills.

Moreover, teachers are required in the learning process because they acknowledge some student's deficiencies and help them to solve their problems by repeating the same explanation, giving extra exercises or even suggesting a private tutor. Hence, students can have a bigger chance not to fail in a subject.

In conclusion, the role for teachers in the learning process is still very important and it will continue to be in the future because no machine can replace the human interaction and its consequences.

This is a great essay. Looks like Band 8 to me. No improvements are necessary, Keep up the good job!

151. We are becoming increasingly dependent on computers. They are used in businesses, hospitals, crime detection and even to fly planes.
What things will they be used for in the future? Is this dependence on computers a good thing or should we he more auspicious of their benefits?

Computers are a relatively new invention. The first computers were built fifty years ago and it is only in the last thirty or so years that their influence has affected our everyday life. Personal computers were introduced as recently as the early eighties. In this short time they have made a tremendous impact on our lives. We are now so dependent on computers that it is hard to imagine what things would be like today without them. You have only got to go into a bank when their main computer is broken to appreciate the chaos that would occur if computers were suddenly removed world-wide.

In the future computers will be used to create bigger and even more sophisticated computers. The prospects for this are quite alarming. They will be so complex that no individual could hope to understand how they work. They will bring a lot of benefits but they will also increase the potential for unimaginable chaos. They will, for example, be able to fly planes and they will be able to co ordinate the movements of several planes in the vicinity of an airport. Providing all the computers are working correctly nothing can go wrong. If one small program fails disaster.

There is a certain inevitability that technology will progress and become increasingly complex. We should, however, ensure that we are still in a position where we are able to control technology. It will be all too easy to suddenly discover that technology is controlling us. By then it might be too late I believe that it is very important to be suspicious of the benefits that computers will bring and to make sure that we never become totally dependent on a completely technological world.

Sample 2:

Today computers are used almost everywhere, it is impossible to imagine our life without PCs, Internet, hand phones and other computer devices. It is reasonable that people look to the future of computers. In what field will be computers used for and what role will human has in this world in future?
Besides, computers make our life easier, we can easily get information about any product we plan to buy or place we plan to visit over a second using personal computer and Internet. Scientists predict that in the nearest future it will be possible to smell a new perfume using Internet and watch 3D scenes at home like we do in the theater. According to forecasts of HR agencies machines will replace job of cashiers, civil and military pilots. Some corporations in Japan already selling
housewife-robots, which help old people to keep their home clean.

Despite the fact that computers help us, they make us dependent. Apparently, people spend more time behind monitors that ever before. And some of them feel a need for more time to be spent with people in live contact. In addition, fall out of one of the important modules of specific computer can entail serious consequences. Suffice to mention computer problem, occurred in the end of 1990s, problem concerned with coming year 2000 (Y2K) and catastrophes that were predicted. Fortunately imminent disasters did not happen. However, it is difficult to imagine what could be if all the predictions had occurred.

We live in technological era, computers penetrated everywhere with all benefits they provide and all dangers they hide. However we are satisfied with them and sometimes we even thank them because they help us in communicating, studying, doing business, entertaining and saving lives in critical situations.
