Technology in Education embraces the use of audio-visual media, 

information and communication technology and educational data 

processing and tele-communication. This dimension of educational 

technology involves the use of equipment of hardware machine (audiocassette player, video cassette player, overhead/slide/film strip projector 

and other projectors) and materials or software (audio-cassette, videocassette, transparencies, slides, filmstrips) in education and training. Every 

teacher and student in every part of the world should be familiar with such 

traditional technology in education like the chalkboard, charts, pictures, 

portable board and models in the classroom. Such instructional devices 

have been commonly referred to as “teaching aids” or “audio-visual aids”. 

In the field of educational technology the work and “aid(s)” is not 

commonly used. With modern technology, virtually all of these older 

instructional media have been greatly improved, and new ones have been 

developed and introduced into the classroom. There are now instructional 

devices that teachers use to facilitate their teaching and those that can even 

stand in for teachers. The two types of instructional materials are now 

called educational media. Thus, today’s technology in education includes 

the following educational media.
