Highlights

• Andrew introduces the CI Immersion podcast and explains his long-term goal: to publish the complete, classroom-ready CI Immersion system for teachers.
• Core premise: language is acquired when learners process meaning in the target language, not simply by spending time in class.
• A simple model of comprehension: sound waves become electrical signals, which the brain matches against a growing mental model of the language.
• Clarifying terms: input is the language learners hear or read, and comprehensible input is input that carries a clear, understandable message.
• Instructional stance: grammar can play a supporting role, but explicit instruction has limited impact compared to large amounts of meaningful, comprehensible repetition.
• Growth principle: aim for i+1 input, language that is just beyond the learner’s current ability. Too easy leads to stagnation; too hard turns into noise.
• Memorable analogies: magnets pulling at the right distance, learning to swim in the shallow end with support, and the brain filtering background noise.
• Practical emphasis: acquisition is a numbers game. More true processing hours leads directly to greater proficiency gains.
• Motivation loop: visible progress creates confidence and momentum, which encourages learners to keep showing up for more reps.
• What’s next: future episodes will focus on concrete implementation steps, and the show will also appear on the Listen, Read, Interact feed.
