If you’ve ever wondered why some language learners seem to pick up Portuguese effortlessly, or why reading and listening can feel more powerful than memorising lists of words, this is the page for you. Here, we dig into the theory behind the method I use in my lessons and stories.
Where this all began: Krashen’s Input Hypothesis
In the 1970s and 80s, linguist Stephen Krashen developed the Input Hypothesis, a theory that still shapes language teaching today. Krashen’s key idea? Language acquisition happens best when learners are exposed to input they can understand, slightly above their current level. This is the foundation of Comprehensible Input (CI).
Input vs Output: Why speaking isn’t enough
Some learners think: “If I speak and write a lot, I’ll acquire the language.” But research suggests otherwise. Linguist Merrill Swain proposed the Comprehensible Output Hypothesis, which says output (speaking and writing) is valuable, but it’s not the main driver of acquisition. Rather, output is an effect of having had enough comprehensible input. In other words, you can’t “force” acquisition by speaking alone – your brain needs exposure first.
What is TPRS?
Firstly, TPRS (Teaching Proficiency through Reading and Storytelling) is a dynamic language teaching strategy that joins the art of storytelling with the power of reading. The beauty of TPRS lies in its simplicity and effectiveness. Here’s a quick breakdown of its core principles:
- Comprehensible Input: Ensuring that the language is understandable to the learner.
- Personalisation: Making the content relatable and interesting to the students.
- Repetition: Using frequent repetition to help students internalize vocabulary and structures.
- Storytelling: Crafting engaging stories that incorporate new language elements.
- Reading: Reinforcing spoken language through reading activities.
Circling: the secret behind CI lessons
One of the tools used in TPRS (Teaching Proficiency through Reading and Storytelling) is circling. This is a structured way of asking questions about a story or sentence multiple times, in slightly different ways. The brain hears the same language repeatedly but in a way that’s engaging, so connections are formed naturally, without memorisation.
Lesson structure in CI
Comprehensible Input lessons follow a simple pattern:
- Introduce new vocabulary and phrases in context.
- Circling questions to reinforce understanding.
- Use the vocabulary repeatedly in stories or dialogues.
- Check comprehension in fun, low-pressure ways.
This repetition is key: the brain learns by exposure, not by memorising rules or translations.
Why translation can slow you down
Translation interrupts the natural process of acquiring meaning. When your brain relies on first-language equivalents, it spends energy decoding instead of absorbing language patterns. In CI lessons, we aim to understand directly from context – this speeds up acquisition and builds intuition for Portuguese.
