This qualitative study investigates the ways that five secondary teachers developed and presented personae. The researcher collected and analyzed data using a theoretical frame based in social psychology, including Goffman's Presentation of Self in Everyday Life (1959), and Miles and Huberman's (1994) three-step approach to qualitative data analysis. Findings indicate that teachers drew on three major realms--the physical, psychological, and social--when constructing classroom personae. Implications include increased opportunities for teacher reflection on persona and its effects. (Contains 2 figures and 1 table.)
