Computers have been favoured by more and more educators and teachers as a key component of a perfect educational environment, its role in a traditional classroom is
nevertheless
a subject of debate, with myriad arguments being advanced both in support of and against its impact on the role of a
teacher
.
One of the major drawbacks of the
computer
is lack of flexibility. Due to its programmatic limitations, its teaching is uniform, repetitive, standardised and
therefore
unsuited to the specific needs of a student.
For example
, it can only answer to questions which have been programmed into
fails to answer any unusual, non-standard and unprecedented question.
By contrast
, a human
teacher
is able to respond flexibility
giving well-tailored, persuasive and inspiring answers. For
this
reason, a
computer
hard functions as effectively as a human
teacher
does.
Another disadvantage of the
computer
, which makes it unaligned with the philosophy of the contemporary education, is its failure to interact with students. Out of technical constraints, the
computer
is interested in eliciting the desired response only. Students’ unexpected performance, potentially exceptional and distinguished, is not recognised by the
computer
. It is fair to say that computers achieve nothing but make all education into an uncritical type of vocational training. Students are conditioned to absorb information without questioning and given no chance to express their personal opinions.
There are some other problems inherent in the
computer
-based teaching,
such
as inability to discipline students and failing to attend to students’ emotional needs, making
this
model of teaching not as competent as the traditional style.
However
, the contribution of the
computer
as a teaching aid can never be underrated. It not only assists teachers to present educational materials in diversified
also
provides repetitive drills to improve the students’ command of knowledge. With the
computer
, the
teacher
can spend less time on
paper workwork that involves handling papers: forms or letters or reports etc.
and concentrate more on the development of a student in other aspects,
such
as creativity and teamwork skills. It is essential to advancing rounded education.
Taking into consideration those above-mentioned characteristics of
computer
-based teaching, one can conclude that the
computer
can only serve as a teaching aid, facilitating students’ interest in a topic and assisting them to take in information faster, rather than taking the place of the
teacher
.
