Stephen Krashen

Stephen Krashen is a linguist known for his work on language acquisition. He proposed that people learn languages naturally through exposure and meaningful communication rather than just formal studying. His "Input Hypothesis" suggests that learners acquire language best when they encounter "comprehensible input"—information just a bit beyond their current level delivered in a relaxed context. Krashen also emphasizes the importance of motivation, low anxiety, and a supportive environment for effective language learning. His ideas have influenced how languages are taught worldwide, promoting more immersive and communicative approaches over rote memorization.
