CONCEPT OF EDUCATIONAL TECHNOLOGY

7. MEANING OF EDUCATIONAL TECHNOLOGY
There are two meaning of educational technology . They are
1. Technology in education
2. Technology of education
1.Technology in education
Technology in education refers to the use of the technological
advancement in terms of various equipment , materials and
machines for educational purposes . It involves the use of audio-
visual equipments, electronic devices like projectors ,films ,radio
,T.V , teaching machines , computers etc.,
Technology in educational serve the following purposes.
 It provides the needed equipments for the realization of different
functions of education.

of equipments.
 Develop a positive actitude towards these appliances.

8. 2.Technology of education
It is the application of phychology of
learning theories , principle of instruction ,
curriculam and learning to the process of
education .Technology of education is the
techniques and methodologies of the
teaching learning process.
There fore educational technology
accept in its fold both technology of
education as well as technology in
education.

9. 1. According to Leith (1967) educational
technology is the application of scientific
knowledge about learning and the
conditions of learning to improve the
effectiveness and efficiency of teaching and
learning.
2. Educational technology is the development
, application and evaluation of the system
techniques and aids to improve the process
of human learning(National Council of
Educational Technology-UK)

11. Eric Ashley (1967) talks of 4 revolutions in education
1. Revolution of shifting the task of educating the once from parent
to teachers and home to school. (oral teaching)
2. Revolution of adaption of the written word as a tool of
education.(invention of writing)
3. Revolution as a result of invension of printing and wild
availability of books and other teaching learning
material.(invention of printing)
4. The fourth revolution is the development in electronics ,notably
those involving the Radio, T.V, cassette recorder and computer
and development of systems consernt that is the fourth revolution
is the educational technology it self.
