Review:
Input Hypothesis (krashen)
overall review score: 4.2
⭐⭐⭐⭐⭐
score is between 0 and 5
The Input Hypothesis, proposed by Stephen Krashen, is a theory in second language acquisition that emphasizes the importance of comprehensible input for language learning. It suggests that learners acquire language most effectively when they are exposed to language input that is slightly above their current proficiency level (i+1), allowing them to naturally develop their skills through understanding messages rather than explicit instruction.
