The computer is widely used in education，and some people think teachers do not play important roles 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.
