Technology refers to the application of scientific knowledge for practical purposes. Educational technology uses engineering, information science, and behavioral sciences to promote efficient education. It has three meanings: 1) using mechanical tools for instruction, 2) applying psychological learning principles, and 3) incorporating both through systematically planning, implementing, and evaluating educational systems according to scientific principles to achieve objectives. Educational technology aims to build community, encourage critical thinking, reward risk-taking, focus on all learners, value diversity, nurture all learners, pursue innovation, and break down walls. It utilizes all educational resources in an integrated way for optimized learning.

2. • The word technology is derived from the Greek
word ‘Technic’ meaning Art or Skill and ‘Logia’
meaning Science or Study. Thus Technology is the
Science of study of an art or skill.
• Tech is the set of instruments and skills which
areused to satisfy the needs of the community.
• Tech is the application of scientific knowledge to a
practical purpose.

3. EDUCATIONAL TECHNOLOGY
• It is a branch of study in which the results of
engineering techniques, information science,
natural sciences, behavioural sciences and
human technology are to be used to promote
the efficiency of education.

4. Meaning of Educational
Technology
The term educational technology has three broad
connotations:
Educational Technology 1 (ET 1)
Refers to the application of physical science and
engineering technology to provide mechanical or
electro-mechanical tools, instrumentation or 'hardware'
which can be used for instructional purposes.

5. • Educational Technology 2 (ET 2)
• Refers to the application of scientific principles to
instruction
• Includes psychological principles of learning

6. • Educational Technology 3 (ET 3)
• Incorporates both ET1 and ET2
• Educational technology, according to this view,
implies planning, implementing and evaluating a
system in education according to scientific
principles so as to best achieve the educational
objectives.

9. PRINCIPLES OF EDUCATION
TECHNOLOGY
• Build Community
• Encourages Critical Thinking
• Reward Risk Taking
• Focus on all Learners
• Value Diversity
• Nurture all learners
• Pursue Innovation
• Break down the walls

11. OBJECTIVES OF EDUCATIONAL
TECHNOLOGY

12. SCOPE OF EDUCATION
TECHNOLOGY

13. CONCLUSION
• Educational Technology is as wide as Education
itself. Educational Technology implies the use of all
educational resources –Men, Materials, Methods
and Techniques, Means and Media in an integrated
and systematic manner for optimized learning.
Educational technology can be considered either as
a design science or as a collection of different
research interests addressing fundamental issues of
learning, teaching and social organization.
