The Role of Social Media in Enhancing Incidental Language Learning

Abstract

This paper focuses on the role of social media platforms in incidental language learning, or language acquisition as a by-product to doing non-pedagogical communicative acts, and that social media platforms can be used as a significant affordance to vocabulary development, pragmatic competence, multimodal literacy, and motivation. Basing on cognitive and sociocultural theories of second-language acquisition, synthesising data of the empirical and conceptual research, the paper recognises the mechanisms of how social media promotes incidental learning (ubiquitous exposure, repetition of retrieval opportunity, contextualised input, and peer interaction), features of different platforms to particular learning processes, and pedagogical implications. The article also identifies limitations (noise and distraction, shallow processing, unequal access, and privacy concern), design ideas to teacher-mediated use, and future research directions to help us learn more about the influences of social media patterns, affordances, and algorithms on learner attributes to determine how they proactively generate incidental language findings. The conclusion has implications to the classroom practitioners, instructional designers and policymakers interested in utilizing social media ecologies in a responsible manner in an effort to supplement formal instruction of language.
