The Effects of Gen‐AI on Situated and Future‐Driven Academic Writing Motivation
International Journal of Applied Linguistics, EarlyView.ABSTRACT Despite the increasing use of Generative Artificial Intelligence (Gen‐AI) in education, there is still a significant gap in understanding its effects on the situated‐ and future‐driven motivation in academic writing. This longitudinal design‐based research sought to explore variations in academic writing motivation of 110 Chinese university ...

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.
