The Impact of AI‐Assisted L2 Learning on Learners’ Emotions: A Meta‐Analysis
International Journal of Applied Linguistics, EarlyView.ABSTRACT The scope of research on AI‐assisted second/foreign language (L2/FL) learning has expanded beyond learning outcomes to focus on learners’ emotional experiences. Despite their proliferation, existing empirical findings are inconsistent, and few studies have systematically synthesized the impacts of AI‐assisted L2 learning on learners’ emotional

Off‐Task Talk to Manage Relationship Work During Student Group Work in Second Language Classrooms
International Journal of Applied Linguistics, EarlyView.ABSTRACT This paper presents a conversation analytic study on student relationship work in off‐task talk (OTT) during group work in foreign language classrooms. Often seen as disengagement from tasks, OTT's social and relational functions in student classroom group interaction and formation remain underexplored.
