Two university English seminars were video-recorded to provide data for a pilot project investigating how English is produced or "actualized" in teaching and learning encounters. The project is positioned within three contexts: national policy about higher education teaching; current research about higher education pedagogy; and, the history and politics of university English. The main aim of the article is to explicate a methodology that takes as its data actual moments of teaching, captured on video tape, and the teachers' commentary on them. It analyses these records with reference to theories about rhetoric. (Contains 2 notes.)
