Explanation : Linear model of communication is a one-
way communication process which does
not include feedback, or the feedback is
quite delayed. Since there is no feedback,
the level of cognition is unperceivable
and the only result expected is semantic
accuracy from the encoder/teacher.
Psychological disruption and high level of
obstruction are not applicable as it is one-
way communication; removal of physical
noise cannot be ensured as it is teacher-
centric and learners are not involved.
