Krashen’s Theory of Second Language Acquisition (Key Hypotheses)

Acquisition vs. Learning

Distinguishes between 'Acquisition' (subconscious, natural process) and 'Learning' (conscious, grammar-focused process), emphasizing the importance of natural language use.

Monitor Hypothesis

Suggests that learners use an internal grammar checker to self-correct their language use based on learned rules, impacting fluency

Natural Order Hypothesis

Proposes that language is acquired in a predictable sequence, which can inform teaching strategies and curriculum design

Input Hypothesis

Argues that learners progress when they receive comprehensible input that is slightly beyond their current level (i+1), promoting language development

Affective Filter Hypothesis

Highlights that emotional factors such as anxiety and motivation can significantly impact language acquisition, suggesting the need for supportive learning environments

Practical Implications

Understanding these hypotheses can guide educators in creating effective language learning experiences
