Final answer:
Krashen and Vygotsky both believe that interaction is key in the Second Language Acquisition (SLA). While Krashen sees language acquisition as a mostly subconscious process, Vygotsky believes conscious learning plays a more prominent role.
Step-by-step explanation:
Both Krashen and Vygotsky have significantly influenced the theory and practice of Second Language Acquisition (SLA). They share a common perception that SLA is strongly influenced by social interactions and context. Krashen's Input Hypothesis posits that understanding language input just beyond our current competence is key to language learning. Vygotsky, in his Sociocultural Theory, emphasized that social interactions play a fundamental role in the process of cognitive development and SLA. Both believe that the interactions in the target language are crucial for SLA. However, while Krashen views SLA as a subconscious process, Vygotsky attaches more importance to conscious processes in learning. So, in essence, Krashen and Vygotsky are similar in their focus on interaction, though different in their emphasis on conscious versus subconscious learning processes.
