Even the best written lesson plan will sometimes need redirecting, and it is at that moment an experienced teacher can demonstrate their flexibility and responsiveness by adjusting their lesson midstream. There are three main causes for teachers to demonstrate flexibility and responsiveness: 1 when an instructional activity is not working, 2 a spontaneous event provides an opportunity for learning (we often call this the teachable moment), and 3 when students display difficulties during the lesson, a teacher presents the material in an alternative fashion. However, to make any change during a lesson, whether small or large, it takes large amounts of courage and confidence which come from experience.
