This study focuses on a secondary English classroom in an East London school, and the multimodal nature of the students' construction of the literary heritage text Macbeth, specifically in their dramatic reinterpretation of Act 1, Scene 7, where Lady Macbeth persuades "Macbeth" to pursue his ambitions and kill the current king, Duncan. From this classroom event, this study goes on to explore how a social semiotic reading can reveal insights into school students' learning and recreation of this text.
