“…Despite its considerable learning potential, informal mobile language learning (IMLL) remains largely uncharted territory (Godwin- Jones, 2019). The limited research on IMLL often adopts a variable-centered approach, viewing learners' IMLL experiences, their linguistic and educational background, motivation and emotion, as well as learning outcomes as separate variables, and examining the association and interaction between them (e.g., Lai & Zheng, 2018;Ma, 2017). In the wake of an increasingly accepted view that recognizes language learning as a dynamic process in which learner-internal and -external variables are concurrently at play (e.g., de Bot, Lowie & Verspoor, 2007), a shift of paradigm from variable-centredness to person-centredness is occurring.…”
