THE ROLES OF INPUT AND OUTPUT IN SLA
Abstract
This paper explored the roles of input and output in second language acquisition (SLA). Terms such as comprehensible input, input quantity, quality, mode, and conditions, interdependencies, output hypothesis, and Kistanova’s and Ryan’s experimental research were discussed. Stephen Krashen’s 1985 Input Hypothesis and Swain’s Output Hypothesis provided the foundation for this study. It was found that both input and output are essential components of language acquisition; input is used to expose and reinforce new language, while output allows learners to validate and reformulate language for true fluency and understanding. Additionally, it was discovered that a balance between input and output is necessary for successful language acquisition..
