2013年雅思考試寫作范文20
“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( 想想什么課程用電腦教不好), 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.
