consider when deciding how education will in our
schools and classrooms :
 Instruction should be student-centered
 Education should be collaborative
 Learning should have context

4. Technology is a tool, a way
for fact- based learning and
allows students to do a lot of
the research using the
internet and various tools.

5. The Role of Technology in The 21st
Century Education
1.)Technology allows for 24/7 access to
information
-You can use it every time and
everywhere you want. It also help you to be
updated every time.
2.)Constant social interaction

6. 3.) Easily created and shared digital
content
-You can create your work easily

research it in the internet, you can share
also your work to others and others can
also shared their data with you.

7. SLIDE PROJECTOR
A slide projector is a specialized projector
which has been designed to be used with
slides. Slides are small transparencies
mounted in sturdy frames which are ideally
suited to magnification and projection,
since they have a very high resolution and
a resulting high image quality. The use of
slide projectors is in decline, as other
projection methods have become more
popular.

8. A projector has four main elements:
 Electric incandescent light bulb or other light source (usually fan-
cooled)
 Reflector and “condensing” lens to direct the light to the slide
 Slide holder
 Focusing lens
The rack for slides is surrounded by a light source and focusing
lenses which ensure that the light passes through the slide, and
allows for focusing so that the slides will appear crisply on the
projection screen. Slide projectors can be adjusted to project at a
variety of distances, with the use of focusing tools. The device also
classically includes a fan to ensure that the workings of the slide
projector do not get too hot, as heat can damage the slides.

10. Functions of Educational
Technology
1.) Improvement of teaching
-Educational technology analyses the
process of teaching thoroughly. It tries to
find out the different techniques, the
phases of teaching principles of teaching
and effects upon each other. If your
technique and principles is well-
developed it will help you improving the
quality of education

11. 2.) Analyses of Teaching-Learning Process
-It tries to find out the different variables
of teaching their interlinks effects upon each
other, relationships. It tries to establish better
relationship between teaching and learning.
3.)Improvement of Learning
-It facilitates more and more of learning
in less time. It takes the help of various
established generalizations from psychology,
sociology, physical sciences, engineering and
many others.

12. 4.)Enhancing Goals of Education

according to the materials and is to be able to bring about
effective teaching learning. The strategies are being involved
by educational technology. The knowledge of those
strategies is a must for every teacher.

14. 9.)Development of Audio-Visuals
-Audio-visuals have always played an
important role in teaching-learning process. They
need be used according to times. The software
aids, the hardware aids, the computer and other
such appliances and equipment have to be used
in the present type of teaching-learning
environment.
