“Get up, boy, it is time to go to school.”
“I dislike having get up early. I can take an on-line lesson at anytime I like.”
It is a completely ordinary dialogue occurring in modern life. Yes, it is the com puter, whose ever-accelerated updating brings about tremendous changes in our sch
ool lives. A typical application is Computer Assisted Instruction (CAI), which ai ds teacher to impart knowledge to student more efficiently by it?s multimedia ch aracters. However, a vigorous debate over the issue whether or not teacher are by no means important in pedagogy field has intrigued the public. In my submission, the computer can be great help of teacher but they can never replace or surpass the position of teacher. I will offer the following reasons.
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.
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.
