Ryoo, Hye-Kyung. 2017. “Discourse Analysis of Microteaching: Dynamic Identities and Situational Frames”. The Sociolinguistic Journal of Korea 25(2), 165~196. The present paper is based on a discourse analysis of Microteaching speech events of Korean pre-service training students taking a teacher training course in college. The purpose of this study is to look closely into what really is going on in the discourse of microteaching events in terms of the participants' identity enactment and framing of situations. Fifteen pre-service training students' microteaching lessons were video-taped and transcribed to examine detailed discourse features. The results of the qualitative analysis of the discourse revealed frequent dynamic shifting and enactments of identities in momentary situational frames. The participants in the present study were able to act on diverse situational frames by orienting to locally-managed situated identities.
