Which of the following is designated as a key behaviour of effectiveness of teaching, as evident from research?

Teacher task-orientation is one of the key behaviours of effective teaching identified in research, keeping the class focused on academic content.

Using student ideas and contributions is a helping or catalytic behaviour, not one of the core key behaviours.

Structuring is likewise a facilitating behaviour that supports, rather than defines, effectiveness.

Teacher affect concerns emotional warmth, again a supporting behaviour rather than a key one.

Borich lists five key behaviours: lesson clarity, instructional variety, task orientation, engagement in learning and student success rate.

The catalyst behaviours include using student ideas, structuring, questioning, probing and teacher affect.
