Have you ever wondered why some classroom discussions are lively and engaging and others more like painful interrogations? Why some students always have an answer ready, but others never participate? Why everybody (or nobody) laughs at a teacher’s jokes? What role multiple languages should play in classroom talk? This course gives classroom teachers at all levels and subject areas the analytic tools to answer these and more questions about classroom communication. Each lesson introduces fundamental concepts and techniques of classroom discourse analysis, developing an analytic toolkit and promoting critical reflection on pedagogical practices over five weeks.
