Computer has really played a very significant role in educational technology and the most indispensable tool for ICT revolution. Computer-assisted Instruction (CAI) was introduced as an approach which promotes individualize learning. Information technology is so dynamic that computers used as computing devices are now used in the educative process. It serves two major functions: communication media and audiovisual media.
Communication media – Computers serve as communication tool. Internet has paved the way for this to happen. Email, chat rooms, blog sites, news services, and movies /music/television room are just some of the avenue for communication.
Audiovisual media - Computers served as media for multimedia applications for better teaching inside the classroom, such multimedia are text, sound, graphics, chart, photos, and PowerPoint presentation. Educational websites where learners could log into and learned has also emerged. Not only that it helped improved teaching and learning process but also other institutional functioning such as accounting.
What is the difference between instructional media and educational communication media? The audio-visual aids that served to enhance and enrich the teaching and learning process are referred as instructional media. Examples are blackboard, photo, film, and video. On the other hand educational communication media is comprised of media of communication, such as prints, films, radio, television or satellites. These two upon the advent of the microprocessor which also known as personal computer, merged. This is because with personal computers, any learner can use it as tool for both audio-visual creations and media communication.
The following are some of the programs installed in a personal computer:
· Microsoft Office – Program for composing text, graphics, etc.
· PowerPoint – For presentation
· Excel – Spreadsheet application
· Internet explorer – Access to Internet
· Yahoo or Google – Websites for researching, chatting, blogging etc.
· Adobe Reader – Graphics/photo composing and editing
· MSN – Mailing/chatting/messaging
· Windows Media Player – CD/VCD player, video playing
· Gamehouse – gaming
REFLECTION:
It is important to note that computer is more than just a computing device; in education, it is so much more than just that. It is important for a teacher to be knowledgeable of the different applications of computer. With the knowledge of it, the teacher can extend the wings of teaching and learning process. There are more gates of learning that can be open. Avenues of skill development are made available through computers so it is important for teachers to employ CAI.
APPLICATION:
In my teaching , I will employ CAI. I will exert an effort in learning more about computers so that better assist and facilitate in the learning of my students. Even if I am going to teach science (most likely), I believe that the Internet can provide what’s lacking in my teaching. I will try to deviate from the traditional mode of teaching and employ student-centered approaches with the help of computers; I can makes use of Inquiry-based approach to stimulate and initiate learning in my students.
