2010年雅思考试参考范文:电脑替代老师(6)
The computer is widely used in education，and some people think teachers donot play important roles in the classroom. To what extend do you agree or
disagree?
“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 computer, whose ever-accelerated updating brings about tremendous changes in
our school lives. A typical application is Computer Assisted Instruction (CAI),
which aids teacher to impart knowledge to student more efficiently by it’s
multimedia characters. 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 instructor requires not just these factors but a wealth of experience
and interpret new experiences using that information. The computer after all are
man-made machine.
Secondly, the progress of instruction is complicated and complex, and the
educational achievement of CAI is limited. Some sorts of course, such as basic
educational 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 different. The latter is too impersonal, which ruins the pleasure of
emotional exchanges. Sometimes gazing at the cold flickering screen is a
disinteresting and tiring 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.
