The Roles of Language Input and Output in Second Language Acquisition – Discussions and Pedagogical Implications for EFL Teachers

ABSTRACT: Extensive input and output practice is significantly crucial in language learning. This can facilitate language learners in terms of mastering the target language effectively and sufficiently. Learning a second or foreign language is as similar as acquiring the first language, so the amount of input and output is adequately required. The article first presents key notions of these two principles and how they have been employed in the classroom context. Specifically, this paper then suggests the application of these principles to not only receptive skills but also productive skills to help Vietnamese learners acquire the linguistic competence of the target language.
