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

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.

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

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.

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.

PERIPHERAL HARDWARE DEVICES

Peripheral hardware devices like the mouse, the keyboard, microphone and scanner are also installed in it.

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.

MULTI-MEDIA

means the use of variety of hard wares and soft wares or combination of audio video, graphic designs, animation and computer data.

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.

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.

MODEM

is the machine that interfaces several computers or network so as to communicate with each other over telephone lines.

SCANNER

photocopies images and translates them to images the computer can read.

CD PLAYER

allows the playing and retrieval of information from CD-ROM.

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.

COMPUTER ASSISTED INSTRUCTION(CAI)

soft ware that includes test and activities for individualized instruction, the performance of students are being monitored by the system.

Advantages of the Computer

in Teaching and Learning

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.

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.

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.

Disadvantages of Computer in Teaching and Learning(Lucido and Borabo, 1997)

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.

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.

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.

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.

Indeed, with the computers the gateways of personal, educational, social and even economic progress

has been widely opened.

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.

One can also access up to date information

across the world anytime by chat or

e-mail, thus enriching knowledge and

information.

• sometimes called simply "the Net," is a worldwide system of computer networks.

• instant source of information.

• is a valuable medium for communication.

In addition to educational institutions, government and non – government organizations have gone on line and many more are joining the net.

One can enjoy the benefit of an instant transaction with friends and relatives across the globe.
