Firstly, CAI are designed and programmed by human instructor. They only condense parts of teacher’s experience and intelligence. Moreover, being a successful ins tructor requires not just these factors but a wealth of experience and interpret new experiences using that information. The computer after all are man-made machi ne.
Secondly, the progress of instruction is complicated and complex, and the educati onal achievement of CAI is limited. Some sorts of course, such as basic education al course( 想想什么课程用电脑教不好), are not necessarily to be expressed by the computer to reach productive effect.
Finally, communications and interactions with teacher and computer are quite diff erent. The latter is too impersonal, which ruins the pleasure of emotional exchan ges. Sometimes gazing at the cold flickering screen is a disinteresting and tirin g experience.
Admittedly, though computer may help teacher to provide student with a richer and more effective learning environment, yet they can not substitute the position of teacher, not only today, but the future.

ad of teachers become a controversial issue. From my point, I don’t think computers can take the place of teachers.
First and foremost, computer cannot communicate with students. Every human being has feeling. Teachers are not only teaching students knowledge but also showing their loves to students when they are teaching. How to have a conversation with others and how to take care of others can be learned from teachers. For example, teacher can take you to the hospital when you are sick. In comparison, computers cannot likely to it.
Secondly, computers cannot help students when the get confused. Asking teachers is the best way to do when students get any quires. However, computers do not have this function. Study is a two-way process, teachers can excite students’ imaginations and fire their creations.
Last but not least, computers cannot organize teaching activities instead of teachers. Take England as an example, students need to do a lot of practical experiments, especially in physics and chemistry. When they do these experiments, students usually work together as a group and discuss with teachers. Team work is a very important part to shape students’ personalities.
From what has been discussed above, we might safely say that computers can never take the place of teachers. We should always remember that human beings are the host of technology and computer is a machine no matter how clever it is!

The computer is widely used in education and some people think teachers are not playing an important role in the classroom. To what extend do you agree or disagree?
With more and more extensive use of computers in education, some people claim that the importance attached to teachers has been jeopardized. Therefore, computers will replace teachers in the classroom. However, it seems quite clear to me that learning from teachers is the most important way that cannot be substituted for students. Naturally, some people maintain that computer should instead of the old way of education. They hold that the strong function of the computer offers a new mode of education, which is more interesting, more vivid and more acceptable by children. The students will not face to the serious teachers and calm classes any more, which are replaced by a brand-new world offered by the Internet. In addition, this can decrease the investment on the foundational education and save the human resources and material resources.
As an assistant, computers do help teachers with their work, but they can never replace the important role of a real teacher. The main functions of any computer are storage and calculation. It cannot think on its own anyway. All the teaching data stored in computers are the essence of teaching experience generalized by many teachers during their work. Hence, to assist education, what a computer can do is just to repeat the contents summarized by real teachers.
In addition, each student has different talents and different defects, and accordingly, they may come across various problems during their study. Computer programmer designing the software, however, cannot predict these problems. Therefore, a single computer can never solve these problems without a teacher’s guidance
Furthermore, if the significance of teacher has been weakened, the number of teachers may be decreased, that is to say, many teachers may be laid-off. If such a case comes to reality, series of social problems will break out, such as the drop of working opportunity which will surely make the burden of whole society become heavier and heavier.

as the most important invention in the 21 century,computers have windspread in the world,and the use of it has become the necessity of various spheres both in our work and in our daily life. although computers are also greatly utilized in the education field,teachers are still playing a crucial part on the platform. personally,i believe that teachers should not be replaced by computers due to the following reasons.
being the architect of humanbeings' moral, teachers shoulder the responsibilities of passing knowledge to students as well as shaping them to be real men with good qualities. students may learn some certain knowledge from computers which are cold and senseless, but good qualities can only be taught by teachers.
at the same time,computers might not give detailed and understandable elaboration of complicated theories. after judging whether the answers are right or wrong computers fail to tell them why they make such mistakes. the problems can only be dealt with by teachers.
in addition,some elementary academic exchanges,such as discussion and association,cannot be organised by computers.nevertheless, teachers make up the deficiendy.by this means,students' learning enthusiasm is greatly activated.
above all,computers bring about many significant revolutions in the education field,but teachers are still the hosts of the classroom.we should always bear in mind that men are the owner of technology and no matter how intelligent the computers are,they are merely man-made machines.

Along with the mass use of computer technology in education circles, we are delighted to witness the uncountable conveniences be brought by computer. Some people even argue that teacher will not be important in classroom any more. Is this reasonable? Personal speaking, I oppose holding such a ridiculous conclusion.
In the first place, the feature of teaching defines teachers as an essential part in education. It is well known that teaching is a process of mutual-communication: firstly, teachers impart/initiate knowledge or ideas to students, then students should promptly transfer their feedback to teachers, moreover, teachers will give students the final interpretation according to their specific requirement. Besides, teachers also can (teach students in accordance of their aptitude). In contrast, what computers can do is merely to display materials which have already stored in their EMS memory or mechanically execute operator’s commands. We actually can not image what our education will being if computers substitute teachers totally.
As to another reason, it seems that teacher’s role as a supervisor is more and more overt. Computer is indeed a controversy, it not only can be an efficient education assistant, but also can become an addiction which includes too much violent and (pornographic propaganda). Youngsters do not mature fully in psychology, therefore, without teachers' supervision, many children would spend hours playing computer games or surfing unhealthy websites, which are regarded as a waste of valuable time and intelligence, instead of trying to have a good command of knowledge and skills.
We never deny that computers are absolutely an available education implements, furthermore, the combination of teacher and computer technology will greatly improve our education quality. However, from all of the grounds of argument mentioned above, we can safely draw a conclusion that teacher will not be replaced by computer in the classroom.
