Research-oriented Presentation (30-minutes) Teacher and Professional Development Room 504

Speaker

Matthew W. Turner (Tokyo University of Science)

Description

This presentation explores teachers’ use of podcasting for professional development, focusing on dialogic co-construction of knowledge. A thematic analysis of 24 episodes spanning seven years identified prevalent interactive features, including knowledge activation, problematising, and strategising. Findings reveal how teachers balance performative and reflective speech and engage listeners through summarisation and intertextual referencing. This presentation seeks to validate podcasting as a learning tool for educators, contribute language-led insights, and encourage the audience to consider such activities.
