“…Shifts of this nature were already under way during the 1990s, as seen in publications which drew on sociocultural theory (SCT) to account for collaborative activity within tasks, including Swain's influential contributions (e.g., 1995). This trend has continued into the present era, with a number of approaches to SLA shedding light on various aspects of learning through tasks, including further contributions based on Vygotskian perspectives (e.g., Storch, ), as well as conversation analysis (e.g., Hellermann, ; Seedhouse & Almutairi, ), complex systems theory (e.g., Dörnyei, ; Poupore, ), language socialization (e.g., Duff & Kobayashi, ), and systemic functional linguistics (e.g., Byrnes, ). Importantly, the new directions in which this theoretical expansion are leading can no longer be aptly described in terms of an incommensurable cognitive versus social divide; rather, the emerging visions for the wider SLA field are those of complementarity, integrativeness, and transdisciplinarity (e.g., Atkinson, ; Cadierno & Eskildsen, ; Douglas Fir Group, ; Ortega, ).…”
