The document discusses three models of communication: 1. The Shannon-Weaver model depicts communication as a linear process with five elements: a source, transmitter, channel, receiver, and destination. 2. The transactional communication model illustrates how senders and receivers take turns conveying and receiving messages. Frank Dance's helix model emphasizes how communication is influenced by past experiences and expands one's knowledge base over time. 3. The interactive communication model emphasizes that the source must encode a message and the receiver must decode it, and both are affected by their various life experiences during the communication process.

2. SHANNON-WEAVER MODEL
• Known as the mother of all communication
models, the shannon-weaver model (1949)
depicts communication as A linear or one-way
process consisting of five elements: A source
(producer of message); A transmitter (encoder of
message into signals); A channel (signals adapted
for transmission); A receiver (decoder of message
from the signal); and A destination.

5. TRANSACTIONAL COMMUNICATION MODEL
The transactional model of
communication illustrates how the
sender and receiver take turns in
conveying and receiving messages and
are called as “communicators.”

7. TRANSACTIONAL COMMUNICATION MODEL
Frank dance (1967) introduced the helix
model that best illustrates the
transactional model by showing how the
development of communication is based
on previous experiences or behaviors as
well as how the knowledge-base of a
person deepens and expands

8. TRANSACTIONAL COMMUNICATION MODEL
He emphasized, “that communication
while moving forward is at the same
time coming back to itself and being
affected by its past behavior…” dance’s
model also shows how the external and
internal factors that are learned
throughout life influence the person’s

11. •The characteristics of transactional
model
1. Communication evolves from the
very first day (origin) until the
existing moment.
2. Communication is largely
dependent on its past.
3. Concept of time.
4. Communication process is the

12. So to put it in simple terms,
transactional model of communication
involves three principles:
1. People send messages continuously
and simultaneously
2. Communication events that have a
past, present, and future, and;
3. Participants play certain roles in the
conversation.

14. INTERACTIVE COMMUNICATION MODEL
Wilbur Schramm introduced the interactive
communication model where he emphasized
the need for the source to encode the
message as well as for the receiver to decode
the message. These messages will always be
affected by the “field of experience” from
various factors namely; social, cultural,
psychological, situational experiences or
