Tag: Input Hypothesis

The Input Hypothesis, developed by Stephen Krashen, argues that people acquire a language when they understand meaningful input that is slightly beyond their current level. This article explains the role of comprehensible input, the idea of “i+1,” the difference between acquisition and learning, and the lasting influence of the theory on language teaching and second language acquisition research.

Stephen Krashen, a leading figure in second language acquisition (SLA), transformed the way we understand language learning. Best known for his Input Hypothesis and the Monitor Model, Krashen emphasized the importance of comprehensible input, free voluntary reading, and low-stress environments in mastering a new language. His research has shaped modern teaching methodologies, bilingual education, and language acquisition theories worldwide.
