Role play is a great way to get students talking through the key issues relating to a topic, especially if they can take rival viewpoints. In order to get students more engaged with this, I often use group work role cards or get them to make masks.
Another technique is to get students to design a sock puppet for their character as well as working with the other people in the team to construct a dialogue. Then, film the results. In this way, students are able to refer to their script as they ‘perform’ without feeling that they are spoiling the effect.
