ICT Revolution

The Revolution:Information and communication Technology

  At the centre of that ‘revolution’ is communication technologies.

Some are long ago established like radio, TV and phones, optical fibber cable, microcomputers and video recording, tape or video disc etc., Others such as mobile-phones, laptops, palmtops, iPods, satellites are quite new.

Among the older ones, radio and TV broadcasting have been improved, adapted, put to new uses or linked with newer communication technologies. 

Satellite and optical fiber cable help faster communication among computers. The development of microchip technology to store lots of information. As computers are everywhere now the rates have also come down.

Computers in Education:

The age of computer is dawning in schools.

 It is taking over the world swiftly and surely.

 It is quite a jump from traditional teaching – reliance on textbooks – to the computer use.

The computers serve a dual purpose.

They expose students to modern technology while inculcating in them anew scientific approach to learning. 

Commonly used terms for the use of computers in Education are:

CAI   Computer Assisted Instruction

CAL   Computer Assisted Learning

CAT   Computer Assisted Training

CBT   Computer Based Training

CMI   Computer Managed Instruction

CML   Computer Managed Learning

Virtual Class room

Computer mediated Communication

Online

Web based

Mobile learning

Laptop, CD

Educational Implications of Computers:

 Computers may aid the leaning process in the following ways:

 By providing information and instructions ;

 By asking questions;

 By being tirelessly repetitive;

 By stimulating processes;

 By selecting the right speed for providing information for             Individual learners;

By providing opportunities to try different things;

By displaying data dynamically;

By taking away tedious calculations;

By proving information from a large store;

By checking up how well a learner understands a topic Through questions.
