Cold-Calling is a teaching strategy that can significantly enhance student engagement and participation. It involves selecting a student to answer a question or contribute to the discussion, whether they have volunteered to do so or not. Within an education setting, Wait Time is the time between a teacher asking a question and calling out to get a response from a student. But why do Wait Times matter? And how can we use Wait Times properly? These resources have been designed to provide you with an in-depth understanding of Cold-Calling techniques and strategies as well as to emphasise the importance of managing your Wait Times when you Cold-Call in your classroom.
