Dual Coding

What is Dual Coding?

Ever spend hours reading or studying, only to forget most of it the next day? Dual coding can help.

This study strategy uses two forms of input — verbal (text or speech) and visual (images, diagrams, charts) — to help you understand and remember information more effectively.

By engaging both the verbal and visual processing channels, you create two memory pathways for the same concept. This makes it easier to store and recall information later. Research shows dual coding improves comprehension, retention, and recall.

Why It Works

• Activates multiple areas of your brain
• Creates stronger connections between ideas
• Encourages deeper understanding
• Speeds up transfer to long-term memory

How to Use Dual Coding

1. Turn Notes into Visuals

• Convert notes into mind maps, diagrams, flowcharts, timelines, or concept maps
• Add visual cues like arrows, color coding, or icons to show relationships

2. Pair Text with Visuals

• Sketch concepts as you learn
• Find or create diagrams that match the material
• Annotate visuals with short explanations
• Use flashcards with imagesFind or create diagrams that match the material
• Annotate visuals with short explanations
• Use flashcards with images

3. Practice Active Recall

• Recreate diagrams from memory
• Cover text and explain visuals out loud
• Teach a friend using drawings or whiteboards

Pro Tips

• Make sure visuals and text are closely connected, not random or redundant
• Create visuals yourself for the biggest learning boost
