The i+1 concept is associated with which approach?

• A. The Natural Approach
• B. The Communicative Approach
• C. The Silent Way
• D. The Direct Method

Answer: (A)

The i+1 concept comes from Krashen’s idea that language is acquired best when learners receive input that is just beyond their current level, in other words, slightly above what they can produce. The Natural Approach centers on this idea by providing abundant, comprehensible input in a low-anxiety, meaning-focused environment, helping learners gradually acquire language without being pushed into production too soon. The other approaches emphasize different mechanisms—interaction and function in the Communicative Approach, discovery through structure in the Silent Way, and immersion without explicit focus on graded input in the Direct Method—so they don’t anchor the i+1 idea as clearly.
