2. “The roles and
functions of
Educational
technology in the 21st
century Education”

3.  Here we are to talk about technology
and the role it plays in 21st century
education .Technology is by far the most
popular topic concerning 21st century
learning and education and many of the
videos on YouTube are about just that.
Although some of these videos cover
other ideas, technology still seems to be
the central focus. So the purpose of this
article is two-fold: One is to address
some of the misconceptions out there
about technology and also is about how
to implement technology effectively and
use in practical pragmatic way.

4.  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.
The place of technology in
pedagogy is based on various factors
and questions of effectiveness, time
saving, increased outcomes etc.

5.  Another issue up with technology
at the moment is the poor
investment in such technology
without the support and
consultation of EdTech staff.
Schools are spending money on
technology but they don’t know
what it's for how to use it. And
because they spent so much
money on the technology they lack
in spending more on training
teachers properly on how to use it.
So the end result of this is that
things such as interactive
whiteboards end up being glorified
TV sets in the classroom or simply
used as regular whiteboards.

6.  When schools cut corners in terms of
spending on technology the result of this is
that the things that they do buy are already
outdated before they have bought them. For
technology to be relevant, constant
investment has to be made in that
technology, its replacement and updating. I
think that any investment in technology has to
be made very consciously of the reasons why
and how it's going to be implemented within
the school, otherwise its money down the
drain. Here is where role of edtech
professionals comes into play.

7. Current Trends in Teaching
and Learning in the future.
 Student-Centered Learning
 Teaching Higher Cognitive and Non-Cognitive
Skills
 The Spread of New Information Technology

8. Student-Centered Learning
- also known as learner-centered education,
broadly encompasses methods of teaching that
shift the focus of instruction from the teacher to
the student.
 The student-centered techniques will not replace
completely the teacher institution-centered
approach but there will be a slow and steady
increase in the use of student-centered learning within
the traditional system.
 To become competent and people must continue
studying.
 New forms of education delivery such as open
university.

9. Teaching Higher Cognitive
and Non-Cognitive Skills
 Increasing emphasis on group learning activities
 Group learning activities has given further
impetus by the development of science and
technology based games, simulation and case
studies.
 Decision-making, communications, and
interpretation skills are now regarded as the
essential part of a properly rounded education.

10. The Spread of New
Information Technology
 IT in all various forms and manifestations is
making an increasing impact on education.
 IT is now becoming the current trend in
equipping quality education.
 IT equipments are rapidly becoming cheap.

12. Overhead Projector in Education
 A device that projects an enlarged image of a transparency placed on
it onto a wall or screen by means of an overhead mirror.
The Overhead Projector, or “OHP” is one of the most frequently used
(and misused) tools in education and training today. It may be facing a
challenge from the data projector, but it is still more flexible and useful
for all except uninterrupted, rehearsed presentations.
NOTES TO USE:
 The use of the OHP or data projector sends a message: “This has
been prepared.” This is in contrast to using the whiteboard or flip
chart, which sends “This is spontaneous,” or, "I am reacting to you".
There is a case for both kinds of message, of course, under
different circumstances.

13. OHP vs. Data Projector
Data projectors are becoming increasingly popular and more
frequently built in to classrooms. If you have to choose, consider
these factors:
OPH
• Not much to go wrong: and if
it does, you can often fix it
yourself
• Restricted in the range of
media it can use: OHTs and a
few transparent or silhouetted
objects
• Can easily take OHTs out of
sequence, to re-cap or jump
ahead to respond to a
question.
DATA PROJECTOR
• Requires a computer as well, and
a link: there's a lot of
temperamental hardware.
• Can use static or animated
graphics, sound and even movie
clips, with a sufficiently powerful
machine
• Needs a dual-monitor set up, if
students are not to see the nuts
and bolts of the set-up when you
want to select a slide out of order
(learn to blank the screen while
you do it)

14. OPH
• OHTs are bulky and rather
fragile
• Temptation to use badly-
designed OHTs: pages of books
copied onto transparencies, for
example.
• You can write on and otherwise
amend OHTs on the fly.
• Students can use write-on OHTs
for reporting back from groups,
etc.
DATA PROJECTOR
• You can put an entire lecture
sequence's material on one
floppy—your entire teaching
career's output on CD or DVD.
• Your presentation package
makes it harder to produce a
bad show than a good one.
• On the whole you are stuck with
what you have prepared.
• Not really practicable, except
with a smart-board

15. Tips for use:
 It's sucking eggs time again! Get the OHP set up for optimum image size,
focused, etc. before the class starts. Make sure everyone can see.
Once you are sure of the above, you have no need to look at the screen. You can
concentrate on the class. Needless (?) to say, don't get in their way.
So do not point to material on the screen itself. Use a pen or other pointer on the
stage of the OHP. If your hand is at all shaky, lay the pointer down on the OHP
stage. Standing in front of the screen to point out salient topics:
- means that you are tempted to talk to the screen and not the class
- means that some of the image is projected onto you, and there is a
large obscuring shadow on the screen
The only exception is when you are projecting onto a whiteboard, and
writing/drawing on the board to elaborate on the image. (This is also the only
occasion when you should project onto a whiteboard, which will also reflect back
the light source, and may well form a "hot-spot" obscuring the image for some
students.) Even this can usually be dealt with more effectively by writing on an
overlaid transparency on the OHP stage.
Do not leave an old OHT showing when you have moved on to talk about
something else. Switch off between OHTs, or at least between sequences.

16. Advantage and Disadvantage of
Overhead Projector in Education.
ADVANTAGES
 Lecture can use it in the same
way.
 Lecture can always face the
class.
 Lecture can use it again and
again.
 OHP serves both as an
outward non-verbal
communication channel for
the teacher and as a means
of obtaining feed back form
the class on how a session is
going.
DISADVANTAGES
 It requires power supply.
 It need a suitable flat surface
on which to project its image.
 Unless the surface is inclined
forward at the correct angle, the
image will probably suffering
from key stoning.
 It requires certain amount of
routine maintenance.

17. ADVANTAGES
 OHP can be used to show pre-
prepared material. The material
projected can be changed easily
and quickly, shapes can be
presented and compared, colors
may be included and exposure
can be controlled.
 OHP does not need room to
blackout. It can be used in well
lighted room.
 Users friendly and does not
require any technical skill or
knowledge.
DISADVANTAGES
 Liable to break down
occasionally.
 It is always advisable to have
a spare bulb.
 Some lectures find glare from
OHP immediately as soon as
the lamp is switched off.
