Role-playing is an unrehearsed dramatisation in which students improvise behaviours to illustrate how they think their assigned character would speak and act in a realistic or hypothetical situation. I have been using role play in my classroom management sessions. Students are found deeply involved in thinking about how they would react in real-world situations. However I have experienced that one of the pitfalls of using role-plays is that they can become ‘entertaining ends in themselves’, rather than vehicles for learning. So I would suggest that you keep the learning outcomes in mind before using them.
