This article describes a strategy employed on a teacher training course in Hong Kong involving the use of lesson transcriptions. Transcriptions from two course participants' English lessons were used to arouse greater classroom language awareness and promote reflection in one of the teachers, who was initially very reluctant to accept comments and suggestions on her teaching and interactive decision making in the classroom. Her attitude underwent a transformation following her exposure to lesson transcriptions taken from another teacher working in a different school but who was teaching the same subject content as she was. The article will document the changes in this experienced ELT teacher and will also show how emphasis upon lesson transcriptions as an alternative to the more conventional video-recording can promote self-reflection and raise awareness of classroom interaction, and exert a powerful influence on teaching and learning.
