The purpose of this study is to investigate narratives of personal experience produced in the classroom, focusing on this discursive practice as a locus for the process of social construction of pedagogic knowledge. The theoretical architecture built in this research is based on the social-cultural theory (Wertsch, [1995]2006, 2002; Daniels, 2001; Wells & Claxton, 2002) developed from Vygotsky’s principles ([1984]1998, 2001); the systemic-functional approach (Halliday & Hasan, 1989; Halliday & Matthiessen, 1999; Eggins, 2004), which considers language as a semiotic mediating tool in the (co)construction of pedagogic knowledge; and the social constructionist notion of narrative as social practice (Bruner, 1994, 2002; Moita Lopes, 2001b; Bastos, 2004, 2008). Six aspects are considered to classify narrative discourse: spontaneity, unconsciousness, integration with pedagogic discourse, narrative time, evaluation, and reportability. Evaluation is examined under two theoretical paradigms: sociolinguistics (Labov & Waletzky, 1967; Labov, 1972; Linde, 1997); and appraisal theory (Martin, 2001, 2006; Martin & White, 2005). Fragments of postgraduate Pragmatics lessons offered at a university in Rio de Janeiro were selected as instantiations of narrative practice. One professor, nine master’s and eight doctoral students, including the researcher herself, took part in this study as narrative interlocutors. The analysis follows a qualitative methodology based on a social-historical approach (Freitas, 2002; André, 2001). The selected extracts were analyzed concerning their connection to pedagogic discourse, Labov’s (1972) narrative structure, and evaluative aspects, which turned out to be highly relevant in the process of meaning negotiation. Results of the analysis also show the multifunctional nature of narrative practices in the pedagogic setting, as well as specific features of classroom narratives, which act as a two-way route in the process of social construction of pedagogic knowledge. Through the telling of experiences in personal stories, formal (educational/pedagogic) knowledge is constructed and, in return, it helps the narrator understand the lived experience, joining the individual to the collective.
