The Nature of Educational Technology

This helps in understanding the nature of educational technology,

1. Evolution of the concept of educational technology.

2. Existing position and latest concept.

3. Distinction from other related concepts.

4.Evolution of the Concept of Educational Technology

It may be discuss as follows:

• The earliest concept of educational technology was link with the use of audio visual aids like charts, models, maps, specimen and concrete material. In this sense, the term educational technology was use as a synonym to audio-visual aids meant for direct teaching and learning.

With the emergence of physical science and electronic revolution there came an era of sophisticated hardware and software. Like  (gadgets and mechanical devices) like projectors, tape-recorders, radio and television. Educational technology takes in terms of these sophisticate instruments and equipment’s use for presenting instructional material.

The advent of mass media. It led to a massive communication revolution for instructional purposes.
