This document discusses a study on implementing dialogic teaching principles in lower secondary classrooms through action research. It describes dialogic teaching as more collaborative between students and teachers, compared to authoritative teaching which is controlled by the teacher. The study involved teacher training seminars, video recordings of classroom lessons before and after training, and student questionnaires. Data analysis looked at changes in teacher and student discourse patterns based on codes for question/reply openness and cognitive demand. The results showed teachers asked more open-ended questions and students gave longer, more cognitively complex responses after the dialogic teaching intervention.
