From the list of effective teaching behaviours, identify those which are called key behaviours.

Direct audible delivery to all students, varying the modes of presentation and preventing misbehaviour with minimum disruption are Rosenshine's key behaviours, so statements 1, 4 and 5 are the answer.

Key behaviours are the essential teaching acts that most directly cause student achievement.

Clear, audible delivery ensures every learner receives the instruction accurately.

Varying presentation sustains attention and suits different learning styles.

Managing behaviour with minimal disruption preserves academic learning time.

Encouraging elaboration, warm relationships and organising-summarising are helping behaviours that support the key ones.
