In this paper, we attempt to investigate the pedagogical value of visual social media platforms, specifically Instagram, for the development of the online social presence of language classes. Students in intermediate university-level French and Italian classes used Instagram for a six-week period to reply to a series of questions prompted by the instructor as a way to engage in interaction with their own classmates. This research examines how students establish a community of inquiry (CoI) and investigates the development of social presence in students' posts. Using a mixed methods approach, we performed a content analysis of the transcripts of Instagram posts, coding for social presence. Given the visual nature of Instagram, we also conducted a visual analysis of representative posts to investigate the multimodal projection of social presence. Additionally, we administered voluntary pre-questionnaires to capture demographic data and students' experience with Instagram. We analyzed the data using the social presence density calculation and performed basic statistical analyses. Findings indicate that students did build online social presence, which can promote the development of a CoI. Both language groups performed in similar ways, which may be a result of the tool rather than the language and context. This finding is consistent with the general use of visual social media as a tool for self-expression, self-identity, and community building.
