Lesson 9: Computer as Information and communication technology

          In educational technology course 1 the role of computer in education was well discussed. It was pointed out that the advent of the computer is recognized as the third revolution in education. The first was the invention of the printing press; the second, the introduction of libraries and the third the invention of the computer, especially so with the advent of the microcomputer in 1975. Thus emerged computer technology in education
          Through the technology, educators saw the amplification of learning literacy. Much like reading, the modern student can now interact with computer messages; even respond to question or to computer commands. Again like writing, the learner can form messages using computer language or programs.
          Soon 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. The novelty of CAI has not waned to this offered by computer-equipped private schools. 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.

FIGURE 6 – USES OF THE COMPUTER AS ICT IN EDUCATION
THE PERSONAL COMPUTER (PC) 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 enhance and enrich the teaching-learning process. Examples are the blackboard, photo, film, and video

                On the other hand, educational communication media comprise the media communication to audiences including learners using the print, film radio, and 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 as distinction merged owing to the advent of the microprocessor also known as the personal computer (PC). 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.

                To illustrate, let’s examine the programs (capabilities) normally installed in an ordinary modern PC:

v  Microsoft Office- program for composing text, graphics, photos into letters, articles, reports etc.

v  Power-point- for preparing lecture presentations

v  Excel- for spreadsheet and similar graphic sheets

v  Internet access to the internet



v  Yahoo or Google- websites; email, chat rooms, Blog sites, news service (print/video) educational software etc.



v  Adobe reader- Graph/photo composition and editing

v  MSN- mail/chat messaging



v  Cyber link power- DVD player



v  Windows media player- Editing film/video



v  Game house- video games
