The rate at which a lesson progresses. This is not about the speed with which the teacher can get through the lesson plan, but rather the sense of engagement and purpose engendered in the learners by the sequencing and length of each activity. The teacher should aim to pace the lesson according to the learners' needs. If it is too hurried, some learners may get left behind; if too leisurely, some may become bored. The pace of the lesson, therefore, calls for a careful balance and, in some cases, differentiation of activity for individuals or groups.
