Educational Technology
in 21st Century
By: Milette Baliber

2. Change is constant and in order to
educate in the 21st century, teachers and
administrators need to cultivate and maintain the
student's interest in the material by showing how
this knowledge applies in the real world. They must
also try to increase their student's curiosity, which
will help them become lifelong learners. Next they
should be flexible with how they teach and give
learners the resources to continue learning outside
of school.

3. 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 of opportunities for
highly skilled individuals and limited
options for everyone.

4. Instruction should be
student-centered

5. It is no longer about listening
to the teacher talk and absorbing the
information. Students will need to be able
to acquire new information as problems
arise. Then, they will need to connect the
new information with the knowledge they
already have and apply it to solving the
problem at hand. They will be able to have
‘learned how to learn’ on their own.

6. Education
should be
collaborative

7. Students must learn how to
collaborative with others. Learners should be
encouraged to work together to discover
information, piece it together, and construct
meaning. They should learn how to recognize
the different strengths and talents each
person can bring to a project, and change roles
depending on those attributes.

8. Learning should have context

9. All learning must be placed in the
learners context if it is to have meaning. While
students are encouraged to learn in different
ways, the teacher still provides guidance as to
the skills that need to be acquired. There is
actually no such thing as "new" knowledge. In
order to acquire new information, the brain
must place it in the context of something that is
already known. You can’t learn what you don’t
already know.

14. Projected
Media

15. Projected visuals are defined as
media formats in which text and still
images are enlarged and displayed on an
illuminated screen. The text and images
are usually printed on a transparent film
such as an overhead transparency or a
slide. The printed material is projected
onto a screen or wall by passing a strong
light through the film and magnifying this
onto a light coloured screen (whiteboard
or white wall).

16. Overhead Projections
These are transparencies or slides
that are prepared from copy and are
shown on a screen. An overhead
projector is a device, which throws a
transparency image on a screen.

17. Here are some tips and rules to be
aware of in using the Overhead
Projector:
1. Practice giving your presentation using your
visual aids
2. Stand off to one side of the overhead projector
while you face the audience
3. Do not face the ”projected” image on the screen

18. 4. Cover the transparency when you are done
using it
5. Bring a spare bulb!
6. Place the overhead to your RIGHT if you are
right handed and to your LEFT if you are left
handed
7. Place your overhead projector on a table

19. 8. Place your screen on a diagonal instead of
directly behind you.
9. Tape the power chord to the floor – to protect
you or someone else from tripping.
10. Store your overhead transparencies in a
sturdy box or container so they will stay clean
and protected for the next time you need
them.

20. Technology is not the solution to 21st
century education, technology is simply a
tool to aid education and learning, also
technology should not be told as a separate
schools subject, but as a tool, technology
should be used in all classrooms. Any
learning concerning technology should be
based around the theme and objectives of
the class.
