This document discusses applying the Sinclair and Coulthard model of discourse analysis to analyze a student-centered English language classroom. It begins by introducing the Sinclair and Coulthard model and noting that it was originally designed to analyze more structured primary school classrooms. The document then examines the model in more detail, exploring the hierarchy of ranks and identifying exchanges, moves, and acts. Finally, it presents sample classroom data and plans to analyze it using the Sinclair and Coulthard model, with modifications if needed to suit the more communicative student-centered context.
