This paper explores the second language, digital multimodal composing practices of 12 American undergraduates studying French abroad in Paris. Drawing on multiliteracies, multimodality, and translanguaging frameworks, this study utilizes a qualitative lens and multimodal composing timescapes to analyze how students leveraged languages and modes across 72 digital multimodal reflections and vlogs. Findings demonstrate how reflective multimodal composing developed multilingual identities by fostering metalinguistic awareness and goal-setting practices. Through their vlogs, students additionally participated in transcultural repositioning by making cross-cultural connections and sharing emotional experiences. Throughout the term students increased in traversals of modes, languages, spaces, and places as they became more comfortable with the French language, living in France, and multimodal composing. These results illustrate how digital multimodal composing can enhance learners’ linguistic and intercultural competencies while studying abroad. The article concludes with implications for multimodal composing to learn languages and calls for further research on the reflective multimodal composing practices of second language learners.
