KRASHEN LANGUAGE ACQUISITION INPUT HYPOTHESIS THEORY

Stephen Krashen's Language Acquisition Theory

  • Significant framework in second language acquisition (SLA).

  • Emphasizes the natural process of language learning similar to first language acquisition.

Key Concepts

Acquisition vs. Learning

  • Acquisition: Subconscious process through meaningful interaction; akin to first language learning.

  • Learning: Conscious process involving formal instruction; not as effective as acquisition.

The Input Hypothesis

  • A fundamental component of Krashen's theory.

  • Principle: Language acquisition occurs when learners are exposed to input just above their current level (i+1).

    • "i" = current level of the learner.

    • "+1" = next level of complexity.

Key Components of the Input Hypothesis

  1. Comprehensible Input:

    • Must be understandable with contextual clues, visuals, and prior knowledge.

  2. Natural Communication:

    • Meaningful communication (conversations, storytelling) enhances acquisition.

  3. Emotional Factors:

    • Motivation, anxiety, and self-confidence impact language acquisition.

    • Supportive, low-anxiety environments promote better learning.

Implications for Language Teaching

  • Focus on Communication: Prioritize meaningful communication over memorization of grammar.

  • Rich Input: Provide ample comprehensible and engaging input (stories, multimedia).

  • Encouragement of Interaction: Create opportunities for interaction with fluent speakers and peers.

  • Creating a Supportive Environment: Reduce anxiety and foster motivation for effective acquisition.

Conclusion

  • Krashen's theory and Input Hypothesis shape language teaching approaches.

  • Advocates for intuitive, context-rich learning experiences, mirroring first language acquisition.
