Match List I (Key behaviours contributing to effective teaching) with List II (Descriptive features):

Lesson clarity (i) is direct, audible oral delivery understood by all students (d), so the presentation is plain and reaches everyone.

Instructional variety (ii) is the teacher's flexibility of delivery during the presentation of a lesson (c), using varied methods and materials.

Engagement in the learning process (iii) is the amount of time students actually devote to learning in the classroom (b).

Students' success rate (iv) is the frequency with which students understand and correctly complete exercises (a).

These are among the five key behaviours that research links to effective teaching.

Gary Borich lists lesson clarity, instructional variety, task orientation, engagement and success rate as the key teaching behaviours.
