Comprehensible Input for Language Learning

comprehensible input is a term. It means input you can comprehend. The base theory behind Krashen's theory is that we learn best at our level plus one. So he puts in a little formula I represents our level, so I plus one is what we learnbest at and that's a comprehensible input. But there's always been a debate out there in the language learning world at really what is plus one. And it's just meant to mean a little bit beyond your current level,. How much beyond, well, enough that you can handle it and keep learning.
