How to Teach Vocabulary in Spanish Class with Comprehensible Input

Have you ever wondered if there’s a solid stance on comprehensible input on how to teach vocabulary in Spanish class? Well, there are many ways, but they all have these core principles in common: context, meaning, and repetition. Read on to see how these examples can play out in your Spanish classroom.

Welcome back to the Practical Proficiency Podcast, the place where we make the transition to proficiency-oriented instruction in your classroom in a way that actually works for you—your unique context, your teaching style, and (most importantly) your well-being.

I’m your host, Devon Gunning, and today I am honored to dive into a listener question from Winchester, Virginia. If you’re in Virginia, holler out! Our friend from Winchester asks:

“I struggle with how to teach vocabulary consistently. I rotate between slides and images, stories, etc., but would like to be more consistent. Do you have any suggestions?”

This is a juicy one. If I could ask a follow-up, it would be: are you feeling like you should have introduced words for longer before asking students to use them? Or are you just looking for a routine that makes planning easier on you? Either way, I’ve got the roadmap to help you move away from “presentation” and toward facilitating acquisition.

Let’s get into how to teach vocabulary in Spanish class using the principles of SLA and comprehensible input as our main source of language fuel.

Listen to the podcast episode here:

1. Why Lists Don’t Work: The Science of “Binding”

Before we get to the how to teach vocabulary in Spanish class, we have to talk about the “what to teach”. In 2026, we’ve moved far away from the old-school 50-word list. Why? Because of a Second Language Acquisition (SLA) concept called Binding.

Binding is the process where a learner interacts with a new structure and it actually “sticks” in their brain’s language processor.

• The Research: Binding works best when a learner sees a word in a context where they need to understand it to follow a story or solve a problem.
• The Visual Advantage: Binding happens faster with an image than with a translated word.

Think of a list of English words on one side and French on the other. That isn’t a teaching tool; it’s a to-do list for the brain. It has almost zero acquisition capacity. Instead, we want social interaction and context.

YOUR PRACTICAL TAKEAWAY:

1. evaluate the new terms for your lesson. Are they more than 15? How can you break them up into context-based segments?
2. Even better, how many terms can you eliminate?
3. How many terms can you replace with a personalized list, based on what your individual students will need?

For example, you don’t ever need to cover ALL of the words from a topic. If you’re teaching hobbies, you only need everyone to know the most common 10-15. But for every other hobby or activity, let kids in your class be the experts! Let them look up and learn their own specific hobbies, and share those words with the class in conversation and activities. This is way more personal and way more realistic to real life conversation.

2. The Lizard Brain Loves a Story

Have you ever wondered why we find movies so addicting? It’s because our “lizard brains” are wired for storytelling. Stories are how humans have passed down information since our primordial days around the fire.

“We didn’t tell kids ‘bears and crocodiles are dangerous’ by showing them a list of nearby predators. We told them a story about the kid who wandered into the forest and got eaten. That’s how the information sticks. We’ve evolved and survived through crucial info passed down by stories.”

When you use a story to introduce sports vocabulary, for example, the words aren’t just definitions—they are tools the student needs to understand if the main character makes the basketball team or brings the wrong ball to practice.

3. The Vocabulary Life Cycle: A 3-Stage Continuum

Consistency doesn’t mean doing the same activity every day; it means following the same sequence for every new set of words. Think of the life cycle of a word as a window: at first, it’s foggy and blurry. Your job is to keep “wiping away the fog” until the word is sharp and clear in the student’s subconscious language processor.

If you see your kids three times a week, this is usually a 3-day cycle. Day 1 is the story (Intro). Day 2 is a game like “Four Corners” (Recognize). Day 3 is a discussion about who likes which sport (Produce).

4. The 10–15 Word Rule: Don’t Clog the Processor

One reason teachers feel “inconsistent” is that they try to de-blur too many words at once. If you try to sharpen 30 words in a single unit, the language processor gets clogged. Some words move to Stage 2, but most get stuck in Stage 1 forever.

• The Sweet Spot: 10 to 15 new terms at a time.
• The Result: You can move that entire set through the continuum smoothly.
• The Trap: Avoid the “Quiz Day Panic” where you assign flashcards because the kids don’t know the words yet. Flashcards put words into the Declarative Memory (short-term facts), but they don’t help the student actually use the language in a conversation.

5. 2026 Tech Hacks: AI & Low-Prep Visuals

You don’t need fancy, ready-to-use slideshows to be consistent.

• AI as Your Writer: Don’t write stories yourself! Use Gemini or ChatGPT.
  • Prompt: “I am a Level 1 French teacher. I need a 7-sentence story with these 10 vocab terms. Make it repetitive, simple, and interesting for 13-year-olds using Comprehensible Input principles.”
• Drawing on the Board: If you’re pressed for time, just draw. I spent a whole year drawing on the board while students filled out reusable vocab sheets. They actually paid more attention because they were following my hand as I drew the “ball” or the “basket.”
• Canva: If you need images, just pull up a blank Canva presentation and search for “basketball” or “tennis” live in class. It’s faster and more dynamic than a static slide deck.

The Upward Spiral

Consistency is simply the “upward staircase spiral” that ACTFL recommends. You start with 10 words, move them through the three stages, and then start a new set while recycling the old ones. Eventually, that spiral becomes wide enough that your students are communicating at a superior level.

To our friend in Winchester: keep rotating those stories and images! You aren’t being inconsistent—you are providing the variety the brain needs to stay engaged. Just make sure you are moving from Introduce to Recognize to Produce every single time.
