Our brains take in information through two main channels: visual and verbal. Dual Coding Theory, introduced by Allan Paivio, shows that when we combine images with words, learners are more likely to understand and remember what they’re learning.
Listen to Dr. Steve Truch break it down in this insightful video:
How to apply Dual Coding in practice:
- When introducing a concept, pair your words with a relevant image like a diagram, photo, icon, or flowchart.
- Encourage students to draw what they’re hearing. It doesn’t have to be perfect, just something to help make it stick.
- Use graphic organizers or annotated visuals alongside your explanations.
- For complex ideas, break things into smaller visual chunks to reduce cognitive overload.
Why it matters:
Relying on text alone can leave many learners behind. Dual coding helps engage both parts of the brain (especially helpful for struggling readers) and leads to deeper understanding. This isn’t a trend; it’s research-backed strategy.
