Medium (pl.
Media) – means through which information is
shared among people participating in any form of interaction. It can be verbal,
non-verbal, written and/or online conversations. Examples of media are such as
language, newspaper, radio, television, magazine, internet, drums, horns,
bells, computers, filers, just to mention a few.

Technology can also be defined as both a process
and a product:-

These are all ancient mean locally produced and

and learning in classroom. Examples are such as drums, language, signs, songs,
dances, pictures, paints, models and simple machines. They are in fact the base
for recent development to modern media.

These are more recent media that appear to be
new or modern in a society. They are either locally made or imported. They may
include electronic technology or equipment such as computer, photocopy, video

Reasons to use educational media
The rapid expansion of education worldwide, more
content diversity, more students in the classroom necessitated the need for
teaching/learning arrangements and materials to meet these diversified needs.

Introduction of
hardware in education (1920-1955). According to skinner (1968), during this
period, educationists began to design and use hardware in classroom. Eg.
Machine designed by Sydney press in 1926 was used in classroom in 1954 at the
University of Pittsburgh. This was due to large number of students in
classroom.

Behaviour perspectives
This belief is held by behaviorists’ school of
thought which stresses on stimulus-response (S-R). The school of thought
believes that, the behavioral change is direct result of the response from a
stimulus. That is, communication involves stimulus (message), originating from
one source and response coming from the other source.

Transitional perspectives

Using this perspective, communication is linear

that communication is in a straight line.

The theory maintains that, communication depends
on existence of institutionalized social practices, that is, actions that are

simplified by drawing the graphs/diagrams which tell by themselves what would
be expected in any communication process.

From the source of information, teachers obtain
what to teach in classroom. This knowledge that teacher gathers becomes the

teacher to be equipped and to be confident before entering the class.

in such situations needs to decide what approaches can make learners pay
attention to the lesson. Some approaches are interactive while others are

According
to this model, for the message to be properly encoded and decoded, the
communication skills of both the source and the receiver should be at best. The
communication will be at its best only if the two points are skilled.

Communication Skills
Communication Skills
An
individual must possess excellent communication skills to make his
communication effective and create an impact among the listeners. The speaker
must know where to take pauses, where to repeat the sentences, how to speak a
particular sentence, how to pronounce a word and so on. The speaker must not go
on and on. He should also make a point to cross check with the recipients and
listen to their queries as well. An individual must take care of his accent
while communicating. A bad accent leads to a boring conversation.

Attitude
Attitude
It
is rightly said that if one has the right attitude, the whole world is at his
feet. There is actually no stopping for the person if he has the right
attitude. A person might be a very good speaker but if he doesn’t have the
right attitude, he would never emerge as a winner. The sender must have the
right attitude to create a long lasting impression on the listeners. An
individual must be an MBA from a reputed institute, but he would be lost in the
crowd without the right attitude.
is rightly said that if one has the right attitude, the whole world is at his
feet. There is actually no stopping for the person if he has the right
attitude. A person might be a very good speaker but if he doesn’t have the
right attitude, he would never emerge as a winner. The sender must have the
right attitude to create a long lasting impression on the listeners. An
individual must be an MBA from a reputed institute, but he would be lost in the
crowd without the right attitude.

Knowledge
Knowledge
Here
knowledge is not related to the educational qualification of the speaker or the
number of degrees he has in his portfolio. Knowledge is actually the clarity of
the information which the speaker wants to convey to the second party. One must
be thorough in what he is speaking with complete in-depth knowledge of the
subject. Remember questions can pop up anytime and you have to be ready with
your answers. You need to be totally familiar with what you are speaking.
Before delivering any speech, read as much you can and prepare the subject
completely without ignoring even the smallest detail.

Social System
Imagine
a politician delivering a speech where he proposes to construct a temple in a
Muslim dominated area. What would be the reaction of the listeners ? They would
obviously be not interested. Was there any problem in the communication skills
of the leader or he didn’t have the right attitude ? The displeasure of the
listeners was simply because the speaker ignored the social set up of the place
where he was communicating. He forgot the sentiments, cultural beliefs,
religious feelings of the second party. Had it been a Hindu dominated society,
his speech would have been very impressive.

It
has been observed that speech alone cannot bring a difference in the
communication. Keep on constantly speaking and the listeners will definitely
lose interest after some time. The speech must be coupled with lots of hand
movements, gestures, postures, facial expressions, body movements to capture
the attention of the listeners and make the speech impressive. Hand movements,
gestures, postures, facial expressions, body movements, gestures all come under
the elements of the message.

If a boss wants to fire any of his employees, he has to be authoritative and
can’t express his message in a casual way. This is referred to as the treatment
of the message. One must understand how to present his message so that the

Schramm’s communication model
Schramm
and Osgood attempted to criticize and modify previous linear models. They
argued that the models were misleading to think of communication process being
a linear process starting from somewhere and ending somewhere.
