Teaching
The Advent of Computers in Educational
Technology
•greatly revolutionized teaching
methodologies and strategies
•teachers are no longer viewed as the
prime source of information
3. Computers as Aids to
Teaching
The Advent of Computers in
Educational Technology
•there is a chain of changes:
@ in the role of teachers;
@in the modes of learning among
students;
@ in the curricular offerings; and
@ in the content in all the three levels
of education
4. Today most jobs including teaching
require that at least the applicants
should possess the basic computer
literacy skills in order to be hired.
Thus it is imperative that computer
applications be a part of the
preparation of the students in teacher
education.

7. A computer is a system. It is a
combination of related parts
performing a unified job of receiving
inputs, processing the information and
transforming them into a new kind of
result.
A computer is made up of hardware
and software
COMPUTER
8.
9. HARD WARE
is the physical part of the machine like
the central processing unit (CPU),
monitor, keyboard, mouse, scanner,
CD player, LCD panel, modem, printer,
disc drive. Simply it is the part of the
computer that one sees and touches.
HARD WAREHARD WARE
13. CPU
The CPU is the brain of the computer
system which holds the computer’s
random access memory (RAM) and its
main storage device or the hard disk.
There is usually a floppy drive and a
CD-ROM or a DVD drive built into CPU.
CPU
18. SOFT WARES
are the programs that make the hardware
function. These are stored in CD ROMS,
video discs, floppy discs, hard drives,
audio tapes and video tapes.
21. MULTI-MEDIA
means the use of variety of hard wares
and soft wares or combination of
audio video, graphic designs,
animation and computer data.
22. INTERNET
is a wide network of computers, its
scope is throughout the world. It is an
international electronic network to
connect schools, universities,
government agencies and various
establishments, offices and
organizations. The internet is the main
connector of all sub networks.
23. ELECTRONIC MAIL (e-mail)
are sent via telephone line networks
from the computer to another, or
through modems which are directed
to a computer address or e-mail
address.
24. MODEM
is the machine
that interfaces
several
computers or
network so as to
communicate
with each other
over telephone
lines.
26. CD PLAYER
allows the playing
and retrieval of
information from
CD-ROM.
27. COMPACT DISC READ ONLY
MEMORY (CD-ROM)
small disc which can incorporate sound,
motion, and video information on specific
topics. It is played in the CD player.
28. COMPUTER ASSISTED
INSTRUCTION(CAI)
soft ware that includes test and activities
for individualized instruction, the
performance of students are being
monitored by the system.
30. Lucido and Borabo (1997) gave the following
advantages of using the computer:
1. It allows students to learn at their own pace by
having control over the rate and sequence of
learning.
2. Learning is reinforced by way of
high speed personalized
response.
31. 3. There is a positive affective climate for learning
especially for slow learners.
4. Color, music, and animated graphics add
realism and appeal to drill exercises,
laboratory activities, simulations and others.
5. Progress in learning is easily monitored with
the record keeping ability
of the computers.
32. 6. Massive information is put at disposal of the
teacher; information which he can control as he
keeps contacts with the learner.
7. Other benefits relating to: motivated work,
improves efficiency, broader memory capacity,
time savings compared with conventional
modes of learning.
34. Disadvantages of the Computer in
Teaching and Learning
1.Computerized instruction is
relatively expensive. The cost and
benefits must be assessed to
ensure optimal gains.
35. Disadvantages of the Computer in
Teaching and Learning
2. There is some lag in the
production and design of
computers for instruction. High
quality direct instruction materials
are not readily available and may
require compatibility due to
exclusiveness of some educational
programs or soft ware.
36. Disadvantages of the Computer in
Teaching and Learning
3.Creativity may be stifled if creative
original responses are ignored by
the linear, lock-step control
learning process in the case of
run-of-the mill computer instruction
materials.
37. Disadvantages of the Computer in
Teaching and Learning
4.The novelty effect associated with
CAI may decrease as computers
are made more easily available at
home and in the workplace.
38. Indeed, with the computers the
gateways of personal, educational,
social and even economic progress
has been widely opened.
39. With computers we can do most
everything. In educational
parlance, teachers and
students as well only need to
lift a finger to do research and
to present illustrations, pictures
and graphics by way of
animation to make teaching
and learning more impressive,
more interesting and
permanent.
40. One can also access up
to date information
across the world anytime
by chat or
e-mail, thus enriching
knowledge and
information.

42. • sometimes called simply "the Net," is a
worldwide system of computer networks.
• instant source of information.
• is a valuable medium for communication.

43. In addition to educational institutions,
government and non – government
organizations have gone on line and many
more are joining the net.
44. One can enjoy the benefit of an
instant transaction with friends and
relatives across the globe.
