“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.
