电脑是否会代替老师的作用？

1、精选优质文档-倾情为你奉上The computer are widely used in education and some people think teacher are not play important role in the classroom. To what extent do you agree?提纲：P1：作为21世纪最重要的发明，计算机已经在一些生活领域普及并成为必须，但在教育界却不竟然。尽管计算机辅助教育广泛应用，教师在课堂上仍然不可少。P2：虽然一些学科计算机可以成功地运用于教学。例如：基础数学，基础语言学习，任何一种需要学生通过重复来记忆的领域都非常适合计算机教学

2、。通过程序，计算机可以毫不厌倦地提供各种问题给学生，通过这种方式强化知识；P3：但是，一些复杂的理论（complex ideas）不能被计算机传授。计算机可以判断（determine）哪个答案是对错，但不能告诉学生错在哪里，也不能以另外一种方式解释这个定义。Tasks involving reasoning can not be taught by computer. 在处理这些问题上，教师必不可少。P4：而且，计算机不能成功地组织一些基本的学习交流，如：讨论（discussion）,联想（association）,比喻（imagery）都是课堂上常用的教学方式，教师可以通过这些方式excit

3、e students imagination and fire their creation. However, it is too complex for a computer to deal with.P5:总的来说，计算机，特别是多媒体信息技术（multimedia technology）给教育界带来许多重要的革命，但老师仍然是课堂的主人。我们应该记住，人类永远是科学技术的主人，无论计算机有多聪明，它只不过是一个电子机器而已。Sample One: Nowadays, computer is rapidly growing in its popularity in educat

4、ion for its marvelous functions. However, the problem has become one whether teachers or computers enjoy a vital role in education, which has aroused wide concern in public. Yet I am, and probably always will be amazed when I hear people saying that teachers are no longer important in education with

5、 the advent of computers. I guess this might be a plausible hypothesis were it not for the following points.On a substantive level, it is often the case that teachers can benefit students in many ways that computers cannot. Indeed, teachers often bring students a host of knowledge and ideas out of t

6、ext books, such as ethics, issues in human behavior and such kind of things. even if there were no hard evidence to support the point that teachers are usually serving as the guide for students, a role which can never be performed by computers, there are plenty of vivid examples that support it. Whe

7、n I was studying in the high school, one of my teachers helped me with my study and taught me how to deal with difficulties in my life as well. So these benefits are impossible to be gained from computers.In addition, a more subtle point can be made is that young students are more susceptible to the

8、 adverse influence of computers. it is a general principle that juveniles usually lack in the sense of judgment to tell right from wrong. so they may be more likely to be distracted from study by the lure that comes along with computers. Therefore, teachers are superior to computers in cultivating s

9、tudents.Although it is all very well to suggest that teachers invariably enjoy the most critical role in fostering young people, let us not lose sight of the dramatic merits brought on by computers. and computers do open  the frontiers of the development of education.nevertheless, I am still in

10、clined to take sides with the opinion that teachers can never give way to computers. as is so often pointed out, the significant thing is to make computers facilitate teachers job.

11、ange among others. However, this is not true for education. At a simple level some subjects may be better taught using computers, but to explain important concepts a human teacher is still indispensable. Introduction shows main ideaThere are some subjects in which a computer can be used successfully

12、 to teach. Elementary mathematics, elementary language leaning, any area which requires a student to memorize basic facts through repetition is well suited to computer learning. The computer can be programmed to provide an endless number of simple questions, and as the student answers these question

13、s the facts are learned and reinforced. Why computers do well, with examples However, in the learning and practice of more complex ideas, computer is not adequate. For one thing, computer can evaluate an answer as right or wrong, but it cannot determine why. It cannot find out why a student is makin

14、g mistakes, and then re-present important concepts in a different way so that the student will understand. It cannot determine at what stage in a mathematics problem the student has made an error. Indeed, it can only indicate that the final answer is wrong. For another, tasks involving reasoning can

15、not be taught by computers, as there are too many variables for a computer to deal with successfully.Thus, while computers may be useful as a tool for practicing simple skills, they are not an essential feature of modern education, because they cannot monitor a students grasp of concepts, nor can it

16、 evaluate a students reasoning. Unless further developments in computers are made will the human teachers remain indispensable? Word count: 276Sample Three:In this period of communication, computer has been widely applied in many fields, and plays particularly significant role in our modern lives. T

17、he most prominent one is that computer has become more and more important in education, therefore dozens of people assert that teachers will be replaced by computers, which will go with the current of the times. The above point is certainly wrong; this essay will outline three reasons.The main reaso

18、n is that peoples brain is better than computer. Firstly, it is humans that design all kinds of computers programs. In another word, computer software is the production of human IQ. Secondly, computer does not have logical creation. Computer can only depend on what designers have input in the comput

19、ers programs to judge if a question is right or wrong. In other words, computer can not independently analyze a question in case that the program designer have completed are wrong. Moreover, the result out of computer will also be infused with plenty of wrong information. Another reason is that comp

20、uters designed programs of education can not be amended accordingly. It usually takes the programmers months or even years to work out a set of workable programs. To change it or amend it may take the same amount of time. The last but not the least reason is computer is mechanical, it may be suitabl

21、e for some students, but not for all with quite different demands. Students, on the whole, are not fond of unchanging teaching methods, fitting and proper for various teaching materials if teachers are working efficiently. In conclusion, it is out of the question for computers to take the place of t

22、eachers in the classroom for the disadvantages of computer in the instruction; however, no one now deny that computer is an absolutely good helper for teacher. Word count: 301 Sample Four: There is no doubt that education and the learning process has changed since the introduction of computers. The

23、search for information has become easier, and connectivity has expedited the data availability. Though expert systems have made computers more intelligent, they have not yet become a substitute for the human interaction in the learning process. In my opinion; what can be expected is a change of the

24、teachers role, but not their disappearance from the classroom. Nobody can argue that the acquisition of knowledge is more fun and easier with computers. The mere activity of touching and exploring this device constitutes an enjoyable task for the learner. This, accompanied with the relaxing attitude

25、 and software interactivity, usually conduce a better grasping of new knowledge. At a higher educational level, the availability of digital books, simulators and other academic materials, provide the student with an ever accessible source of information that would otherwise not be at hand. But besides the increasing complexity of intelligent software, the need of human interaction in the learning process will always be present, at least in the foreseeable future. Human beings are needed to determine what the specific needs of each individual a
