TV, computers have fully integrated into urban life in many spheres like education, entertainment, and commerce, and therefore, some people consider that the technology such as multimedia teaching would replace teachers in class. I would say this does not sound very convincing because the superiority of the teachers are obvious. The first and most apparent advantage that face-to-face conversation is a vital ability for the environment of the social working is clear.
Teachers give students direction to have a good grasp to work in the team or respect each other. It is possible for one to have a video communication with teacher to achieve that, however, the meaning of much of what we say depends on our body language and tone of voice which can not be transmitted by the computers. The interaction between teachers arid students is the core of teaching process. Additionally, it is generally thought that multimedia always connects with Internet which is a double-edged sword.
The Internet with innumerable news sources about curriculum let us make the paradox of choice. For instance, we downland a mass of materials for TOEFL tests but do not know which one to start. Teachers play significant roles to guide our study, and they can tell us where we begin with, what we should do, and which reference we should choose, hence their proposal always make a huge difference especially in a brand new discipline. As a facilitator ,teacher can make us learn efficiency.
Whats more, students,with low self-control, also easier to indulge in bad or rather faulty information and act on it. Teachers also play significant roles in supervising students. In conclusion, the computer has been widely used in class,it cannot replace the role of teachers who impersonated an essential part of modern education. Nevertheless,multimedia teaching facilitates our education like PPT teaching which can avoid the chalk dust. Teachers can use this trait to mend and consummate our education.
