1. ROLES AND FUNCTIONS
OF EDUCATIONAL
TECHNOLOGY IN THE
21ST CENTURY
EDUCATION
Prepared by: Erazon Mae C. Dolera

2. Creating a 21st century education system is about
making sure that all students are prepared to succeed in
a competitive world; a world with plenty opportunities
for highly skilled individuals and limited options for
everyone else. It’s about maximizing the impact of
technology to develop proficiency in 21st century skills,
support innovative teaching and learning, and create
robust education support systems.
Globalization has opened up the world. We blend
traditions, create unique belief systems and transmit our
values and cultures. The role of education is to prepare
students to become active, successful, and contributing
members of the society.

3. The problem now is that schools and teachers are left
trying to figure out what their roles needs to be in the
education of their 21st century students.
In order to prepare students to play their role in the
21st century society we are a part of, the following can
be considered when deciding how education will look
in our schools and classrooms.

4. 1. Instruction should be student-centered
Students need to connect the new information with the
knowledge they already have and apply it to solving the
problem at hand.
Students will need to have ‘learned how to learn’ on their
own.
The teacher would act as a facilitator for the students.
Different styles are encouraged.
Learning is about discovery, not memorization of facts.

5. 2. Education should be collaborative
Students should be encouraged to work together to discover
information, piece it together, and construct meaning.
Collaboration should be dynamic.
Students should learn how to recognize the different
strengths and talents each person can bring to a project, and
change roles depending on those attributes.
Schools should also be collaborating with other educational
institutions around the world.

6. 3. Learning should have context
The teacher provides guidance as to the skills that need to be
acquired.
The teacher can make a point of helping students to
understand how the skills they are building can be applied in
their lives.
Teachers should take a more general approach and teach
them the skills that are useful in any situation.

7. THE ROLE OF
TECHNOLOGY IN 21ST
CENTURY LEARNING
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.
1. Technology allows for 24/7 access to information
2. Constant social interaction, and
3. Easily created and shared digital content

8. It is important for our students to learn in a global
classroom, acknowledging that the classroom extends
beyond the physical walls. Our students are more
inclined to find information by accessing the Internet
through cellphones and computers or chatting with
friends on a social networking sites. If this is the case, it
is necessary to embrace this highly motivational interest
and embed it in our teaching. Teachers will begin to
utilize technology to better meet the needs and interests
of students. There is a call for action to integrate
technology as a fundamental building block into
education in three broad areas:

9. 1. Use technology comprehensively to develop
proficiency in 21st century skills.
2. Use technology comprehensively to support
innovative teaching and learning.
3. Use technology comprehensively to create
robust education support systems.

11. DIGITAL IMAGE
PROJECTION
A digital projector, also called a digital projection
display system, is a specialized computer display
that projects an enlarged image on a movie screen.
Such devices are commonly used in presentations. It
is sometimes used for a program that facilitates
three-dimensional (3D), interactive, full motion
audio-visual files on a personal computer
There are two main types of digital projection display
system.

12. Employs three transparent
liquid-crystal-display (LCD)
panels, one for each of the
primary colors (red, green,
and blue)
The light of each pixel
varies depending on the
image data received from
the computer.
The light from the lamp is
directed through the LCD
panels.
Known as Digital Light
Processing (DLP), a
proprietary technology
developed by Texas
Instruments.
Tiny mirrors are used
instead of transparent
panels.
Each mirror represents one
pixel. The light is reflected
from it.
The older, less
expensive type
The newer, more
expensive scheme

13. This is similar to a slide
projector, where the “slide”
consists of three LCD
panels placed close together
near the focal point of the
projection lens.
Efficient to use, ease of
brightness and contrast
adjustment, and high image
resolution
The mirrors move back and
forth, varying the amount
of light that reaches the
projections lens from each
pixel.
Color is obtained by passing
the light from the lamp
through a rotating wheel
with red, green and blue
filters.
Light weight, high contrast,
and lack of pixelation.

14. IMPORTANT FUNCTIONS OF
EDUCATIONAL TECHNOLOGY
1. Improvement of Teaching
Educational Technology analyses the process of teaching
thoroughly.
It tries to find out the different variables of teaching, their
interlinks and effects upon each other.
By developing theories of teaching, it helps in improving the
quality of education

15. 2. Analysis of the Teaching-Learning
Process
Educational Technology aims at analyzing the process of
teaching-learning thoroughly.
It is also concerned with various phases of teaching.
It ties to establish better relationship between teaching and
learning.
3. Improvement of Learning
Educational Technology analyses the process of learning and
the related theories.
It facilitates more and more of learning in less time.

16. 4. Enhancing Goals of Education
Educational Technology helps in finding out the right objectives.
It helps in enhancing the right objectives in the light of changed
circumstances and changed environment.
5. Training to Teachers
Right type of training to the teachers is the need of the hour.
6. Development of Curriculum
Educational Technology can do this job of developing a suitable
curriculum appropriately.

17. 7. Development of Teaching-Learning
Materials
Materials have to be in accordance with the
environment of the learners.
Only right type of materials will able to modify the
behavior of the learner suitably making him a fit
person for the society.
8. Teaching-Learning Strategies
The strategy has to be the right one, which should be
according to the right materials and is able to bring
about the effective teaching-learning.
The knowledge of those strategies is a must for every
teachers.

18. 9. Development of Audio-Visual Aids
They need to used according to the times.
10. Help in Overall Improvement
Educational Technology helps in locating the
problems in the different areas of education.
It helps in remedying the drawbacks.
It is made better through feedbacks, things are
improved thoroughly and there is better control over
the process of education.

19. 11. Identification of Needs of the
Community
Educational Technology identifies the needs of the
community.
It helps in providing equal education opportunities to
backward people, disadvantaged students and
deprived sections of the society.
