What is meant by 'comprehensible input' in ELL instruction?

'Comprehensible input' refers to language that ELLs can understand, which exceeds their current level of proficiency, providing a challenge that helps them develop their language skills. This concept, coined by Stephen Krashen, emphasizes the importance of exposing learners to slightly advanced language structures and vocabulary in a way that remains accessible. This approach encourages growth by allowing students to make connections and deduce meaning through context while still grasping the overall message.

By ensuring the input is slightly above their proficiency level, educators create opportunities for ELLs to progress in their language acquisition, ultimately facilitating better learning outcomes. The aim is to strike a balance where the language is not so complex that it becomes incomprehensible, nor so simple that it does not promote further development. This method fosters an environment where learners can actively engage with the language and enhance their understanding in a supportive manner.
