Video Summary
Summary
Core Theme
The Shannon-Weaver model, developed by Claude Shannon and Warren Weaver, provides a foundational framework for understanding communication as a process involving a source, encoder, message, channel, decoder, receiver, noise, and feedback, aiming to explain how messages are transmitted and potentially distorted.

communication technologies the title of
this particular video clip is the
Shannon in we've remodeled communication
is quite complex we saw in the previous
video clip that when communication
passes through technology it gets more
complicated there are several competing
explanations to this some of the causes
of misunderstandings arising from
communication have been coined several
decades ago the analysis questions for
this particular video clip are as
follows who were Shannon and Weaver what
purpose does the Shannon Weaver model of
communication surf what are the eight
variables that interplay in 1948 an
American mathematician named Claude
Shannon wrote an article he published in
the bell electrical journal the article
titled a mathematical theory of
communication proposed an explanation of
communication later on Shannon partnered
with an electronic engineer named Warren
Weaver to better apply history to
communication the to put their skills
together to create what became known as
the Shannon Weaver theory of
communication at that time communication
was understood in its simplest mode
there was a transmitter whose role was
to send a message and a receiver whose
role was to decode the message Shannon
and Weaver's objective was to explain
that concept a little bit more in depth
Shannon Weaver presented the following
model to explain the steps of
communication according to their model
there are eight variables that play on
communication there is the source the
encoder the message
the channel the decoder the receiver
noise and feedback in order to
understand this model thoroughly we need
to define each key element this model
begins with the source of a
communication this is where the origin
of the communication stands the source
can be an individual or a group that has
a reason to communicate something in
other words the communication process
begins when an individual or a group
want to give a message to another
individual or group the encoders role
comes in after the source of
communication has been decided the
encoder will transform a concept that
the source wants to send into a format
that will reach the audience who needs
to interpret it the message is the
information that is being communicated
from the transmitter to the receiver
whether or not this message has a
substance does not really matter what
matters is that a message is transmitted
the channel is a means to transmit the
message from the transmitter to the
receiver for a message to be transmitted
it is essential that a proper means of
transmission be selected it is a routes
that the message takes to reach the
receiver this route can be verbal
written electronic audio video etc as
the message travels in a channel noise
comes into play this noise is an
interference or distortion that can
modify the message being sent by the
transmitter or the sender in such a way
that it is misconstrued noise can be
physical semantics pragmatics or
rhetoric before the message reaches this
receiver it has to be decoded in a form
that the receiver understands this is
the other side of the sequence as when
the transmitter encodes the concept he
or she wants to transmit the receiver is
the recipient of the
that was set out by the transmitter or
the sender feedback is when the receiver
tells the transmitter that he or she
received a message and interpreted it
accurately Shannon and weaver put the
emphasis on this section of the model
because it is the only way for the
transmitter or the sender to know if the
communication process was effective this
is where the model becomes cyclical up
until the 1990s this model helped
explain why it was so difficult to take
distance education courses for about 1
century there were two models of
distance education one consisted of
sending a package to the student who
would read text and answer questions and
then send back the modules back for
marking the auto modelled consisted of a
teacher who would transmit a course
through radio waves in which he or she
was giving explanations about work to do
to students such as the school of the
air and remote learning in Australia at
this point you can go to course outline
and find a link to their website where
to talk about the history and how they
evolved with the technological
advancement in both cases there was only
minimal interaction as if the students
had questions they either had to write
to the teacher or call the teacher if
such service was available when the
internet came everything changed the
synthesis questions for this video clip
are as follows do you think that Shannon
Weaver's model applies to digital
communication technologies other
components of the model that apply more
than others can you identify other
problems although the noise or feedback
arising from digital communication
