Which of the following are essential for successful classroom communication?

Successful classroom communication rests on defining the purpose, using humour that carries no risk of offence, and repeating speech-tags so key ideas anchor for learners.

Statement 1, defining the purpose, gives the talk direction so both teacher and class know what the session is meant to achieve.

Statement 3, un-risky humour, warms the room and holds attention without alienating anyone or derailing the lesson.

Statement 5, repeating speech-tags, reinforces signposts so students track the structure and retain the thread.

Opting for pretensions works against this, since a false front erodes the trust that classroom exchange needs.

Avoiding rehearsals also fails, because preparation and practice are what make delivery clear and confident.
