Dual Coding

Shrink Definition

Dual coding is the principle that we learn and remember better when information is presented in both words and images rather than words alone. Verbal and visual channels store information in different ways, so combining them gives two routes to recall. Good diagrams paired with clear explanation outperform either alone. It's a practical rule for studying and teaching.

Plain language

We learn better when information comes as both words and images.

Shrink Insight

Two channels, verbal and visual, remember more than one.

Why it matters

It improves studying and teaching by combining words and visuals. It gives a simple, evidence-based way to strengthen learning.

Common misunderstanding

People think reading or hearing words is enough to learn well. Adding relevant visuals to words improves understanding and recall.

Shrink Perspective

Show it and say it, and it sticks better.

Shrink Reflection

What idea would stick better if I drew it?

Shrink Step

Pair a concept you're learning with a simple diagram or image.

Shrink Takeaway

Words plus pictures beat words alone.
