2. defination of a model
• A model refers to a graphical
representation that is designed to explain
how an object, system or a concept work.
• Models are used to give a summerized
breakdown of a complex concept for easy
learning.
• When used during instruction, they help
improve interaction and used as quick
point of reference.

3. The four models of
communication
• Linear models also called Actional models
• Interactive models
• Transactional models
• Ecological model

4. Linear or actional models
• These are one way communications that do not
require feedback. Example in a radio and
television communication.
• The receiver only receives the message without
replying.
• Examples : >Aristotle model.
>Lasswell model.(1948)
>The transmission model by
Shannon & Weaver(1949)
>The Berlow's model.

5. The Interactive model or
Convergence models
These models involves the exchange of
concepts and messages taking place in to
parties, from the sender to the receiver and
from the receiver to the sender.
The models allow the interaction between
the sender and the receiver as there is
feedback expectation.
 Examples of interactive model is
> Schramm model.(1954) ,(1997)
> Osgood's model(1959)

6. The Transactional model
• These are models that involve exchange
of information between communicators in
an ongoing, continously changing process
in a disorganized way.
• The communicators react to each other as
per social, cultural and relation orientation.
• Examples of transctional models
>Barnlund's model
>Helical model
>Becker's mosaic model

7. The Ecological models
• This models involves the creator(sender)
and the consumer (receiver)
communicating with each other in their
social network , both face to face and
using a variety of media and
communication technologies (language
and devices).

8. • Examples of ecological modelis the new
Foulger's model (2004) ,which is an
advancement of Lasswell's model of 1948.
