This doctoral research examines the identity construction of adult plurilingual learnersthrough their literacy practices in a French as a Second Language class in a FrenchUniversity. This ethno-sociolinguistic study intersects the research fields of secondlanguage didactics and academic literacy in multilingual contexts. It analyzes howlearners create and express their multiple identities through their literacy practices.Learners are considered as social actors using their plurilingual resources to reveal theirmultiple identities. Identities are treated as fluid and ambivalent, changing over time,space and situations, and on what learners want to communicate about themselves. Thestudy is based on classroom interactions recorded over two university terms, textscreated by students and follow-up interviews. We use the tools of discourse analysis, oncontent and form, to show learners' representations on plurilingualism and languagelearning, and their writing process as a way to express their identities. The conclusionoffers a pedagogical discussion for teachers.
