    The Role of i+1 in Second Language Acquisition: Making Input Just Challenging Enough
    (Kyiv, Ukraine, 2025-06-02) Leshchenko, Anzhelika
    One of the key questions in language teaching is: How can we help learners move from what they already know to the next level?

The “i” in i+1 stands for the learner’s current level of language knowledge-what they already understand and can use. The “+1” represents new language – vocabulary, grammar, or structure – that is just slightly beyond that level. According to Krashen, this slightly more advanced input should still be comprehensible. Learners do not need to understand every word, but they should be able to grasp the main idea with the help of context, visuals, tone, or prior knowledge
