“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 #pletely ordinary dialogue occurring in modern life. Yes, it is the #
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 #puter 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 #puter after all are man-made machi
ne.
Secondly, the progress of instruction is #plicated and #plex, 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
#puter to reach productive effect.
Finally, #munications and interactions with teacher and #puter 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 #puter 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.
