It
is
witnessed
that
computer
technology
hasbrought
human
beings
uncountable
benefits
and
aneducational
revolution seemingly can be expected hence a substitution of
teachers in theclassroom. As to discuss this controversial issue,
opinions vary from person to person.
On the one hand, the teacher plays an important role as a
supervisor
as
well
as
aconductor
in
the
classroom
(topic
sentence).It
is
commonly
believed
that
adolescents
are
tooyoung to distinguish the good from the bad and they need
correct
guidance
from
decentadults;
otherwise,
they
might
stray
from
the
right
way.
Children
are
always
easy
to
becomeaddicted
to
computer
games,
which
have
too
much
violent and pornographic t teachers'
guidance,
most
children
would
spend
hours
playing
fascinating
games
oncomputers
instead
of
studying
useful
knowledge
during
school
times.
Moreover,
a
teacher
in
theclassroom may organize a discussion on a complicated or
1

logical
question
and
finallyconclude
with
a
sensible
answer,
but computers can never do so.
On the other hand, in some way, computers can replace
teachers
in
language
learning(topic
sentence).
In
many
countries,
particularly
in
China,
most
English
teachers
have
incorrectpronunciation
in
English.
It
is
not
unusual
that
Chinese
students
have
a
hard
time
tocommunicate
with
English native speakers due to an inaccurate sound producing
methodwhich they have imitated from their Chinese teachers.
However,
if
you
go
online
to
learn
spokenEnglish
with
foreigners,
you
will
be
astonished
to
find
that
thousands
of
native Englishspeakers are available on Internet every day and
they
are
willing
to
help
you
improve
yourEnglish
speaking
skills. Through net-voice-chat, you are bound to speak good
English
with
anassistance
that
you
can
never
expect
to
be
attached by Chinese teachers.
From
above
discussion,
we
can
see
that
computers
and
teachers
play
different
roles
ineducation.
We
cannot
just
arbitrarily
assert
that
teachers
are
not
needed;
on
the
contrary,we ought to take advantage of this teaching resource
despite the application of computers ineducation.

Computers are now essential in many areas of life;modern
banking,
retail
and
informationexchange
among
others.
However,
this
is
not
true
for
education.
At
a
simple
level
somesubjects may be better
taught
using
computers,
but
to
explain
important
concepts
a
humanteacher
is
still
indispensable.
There are some subjects in which a computer can be used
successfully
to
teach.
Elementarymathematics,
elementary
language
leaning,
any
area
which
requires
a
student
to
memorizebasic
facts
through
repetition
is
well
suited
to
computer
learning.
The
computer
can
beprogrammed
to
provide
an
endless
number
of
simple
questions,
and
as
the
student
answersthese
questions
the
facts
are
learned
and
reinforced.
However,
in
the
learning
and
practice
of
more
complex
ideas, the computer is notadequate. A computer can evaluate
an
answer
as
right
or
wrong,
but
it
cannot
determinewhy.
It
cannot find out why a student is making mistakes, and then
re- present
importantconcepts
in
a
different
way
so
the
student will understand. It cannot determine at what stagein a
mathematics
problem
the
student
has
made
an
error,
it
can
only
indicate
that
the
finalanswer
is
wrong.
