This exploratory Australian study tested a novel mobile-based language learning service intervention (via WhatsApp) called 'Chatloop' with 31 newly arrived migrants. This intervention was offered in tandem with the traditional Adult Migrant English Program (AMEP) classroom curriculum. A mixed methods approach was employed to trial the intervention of Chatloop with AMEP students at two Queensland TAFE campuses. Quantitative data were gathered to measure changes in participants' English proficiency, and qualitative interviews gathered narratives about the experience of using Chatloop. Chatloop intervention group participants perceived it to be an interactive learning service that significantly improved their reading and writing skills, acculturation, and enhanced social connections. Being able to access Chatloop on their mobile device 24/7 was deemed to be an added advantage as compared to traditional classroom learning; it provided an opportunity to learn more about Australian culture and communication patterns, at their convenience. These findings suggest that such mobile interventions can be a valuable means of enhancing migrant's English language learning and warrants future research.
