Picture of Serge Bibauw

I am an assistant professor of French language teaching at the University of Louvain (UCLouvain), in Louvain-la-Neuve, Belgium. I am affiliated with the Institute for the Analysis of Change in Contemporary and Historical Societies (IACCHOS) and with Girsef. I collaborate intensely with researchers at CENTALCECL and TeAMM research groups. I am also an associated professor at ITEC, an imec research group at KU Leuven. I was previously a professor and a French and English teacher trainer at Universidad Central del Ecuador.

I study conversational AI for language learning, or dialogue-based CALL, more precisely task-oriented chatbots (or dialogue systems) for language learning, at the intersection of task-based language teaching (TBLT), computer-assisted language learning and natural language processing (NLP). My research focuses on the instructional design and the evaluation of the effectiveness of conversational AI for L2 proficiency development, particularly L2 vocabulary size, spoken and written L2 fluency, and longitudinal assessment of L2 proficiency in various instructed SLA contexts.

Fréquence, formules et fixation : quelques mots sur le vocabulaire en FLE

Le vocabulaire est souvent oublié dans l’apprentissage du FLE, ou relégué à l’apprentissage de listes de mots de fin de manuel. Pourtant, il est essentiel à la communication et la recherche a apporté des éclairages précieux sur les meilleures manières de l’apprendre. Nous en explorerons trois : (1) Comment cibler les mots les plus fréquents et pertinents ? (2) Dépasser le mot pour viser les expressions polylexicales, notamment « formulaïques ». (3) Combiner apprentissage contextuel, notamment par l’exposition, et apprentissage ciblé, notamment par la répétition espacée.
