Lesson 9: Computer as Information and Communication Technology

Introduction 

    Three revolutions in education  

1) Invention of the printing press 

2) The introduction of libraries 

3) The invention of the computer 

  Computer-assisted instruction (CAI) was introduced using the principle of individualized learning through a positive climate that includes realism and appeal with drill exercise that uses color, music and animation. But the evolving pace of innovation in today's information Age is so dynamic that within the first decade of the 21st century, computer technology in education has matured to transform into an educative Information and Communication Technology (ICT) in education.

The Rise of Personal Computer (PC) with a computer in the classroom 

The teacher must: 

1) Demonstrate new lesson, present new material  

2) Illustrate how to use new programs 

3) Show new websites
 

           

The Personal Computer as ICT      

    Until the nineties, it was still possible to distinguish between instructional media and the educational communication media. Instructional media consist of audio-visual aids that served to learning process.Examples are the blackboard, photo, film and video. 

    On the other hand, educational communication media comprise the media of communication to audiences including learners using the print, film, radio, television, or satellite means of communication. For example, distance learning were implemented using correspondence , radio, television, or the computer satellite system.   

   Close to the turn of the 21st century, however, such a distinction merged owning to the advert of the microprocessor, also known as the personal computer .

   This is due to the fact that the PC user at home, office and school has before him a tool for both audio-visual creations and media communication.
