Explanation : Communication is effective only when
the message is completely understood by
the receiver. For complete understanding,
barriers to communication must be removed
or minimised Semantic noise or hindrance to
understanding caused by pedantic vocabulary
or regional colloquialisms, illegible verbal
cues, etc., is one such barrier which can
be minimised by the teacher adapting the
message to the learners' cognitive, affective
and psychomotor skill/aptitude for learning.
