This study aims to investigate the mode-divergent practices of pre-service teachers in an online context. Firstly, 16 h of classroom interaction is analyzed via Conversation Analysis utilizing the Classroom Interactional Competence framework. Then, the translanguaging pedagogy perspective complements this analysis by focusing on linguistic, social, and psychological aspects. The conversation-analytical findings demonstrate the failures in constructive alignment, and an inordinate amount of wasted time with no satisfying results has been observed. It is shown that translanguaging pedagogy may support the creative, critical, and strategic utilization of bilingual students' entire repertoires in classroom practices. Overall, the analysis demonstrates how translanguaging pedagogies can inform mode-divergent practices in classrooms by which teachers’ interactional competence may be improved.
