Pauses separate thoughts. They are powerful and important in effective communication. Periodical pausing allows the audience time to catch up with and absorb the meaning of what has been said. It also builds anticipation and wonder for what is to follow. Pausing after asking a question is a good technique to mentally involve the audience and make them think. An artfully cultivated ‘spontaneous pause’ helps the speaker to change direction smoothly. However, one must be careful not to pause too long to sow doubts in the audience. So, as a good classroom communicator, one needs to know one’s artful pauses well.
