Learning is not a single-channel experience. The brain thrives when multiple systems are activated at once. When students listen, write, draw, and organize information spatially, they engage more than just verbal processing. They build multisensory networks.
Sketchnoting naturally supports multisensory learning because it combines:

• Auditory input (listening to instruction or discussion)
• Linguistic processing (selecting and recording key words)
• Visual representation (drawing symbols, diagrams, layout)
• Kinesthetic movement (physically sketching and organizing)

This layered engagement strengthens understanding. Instead of passively receiving information, students interact with it. They transform it.
Multisensory learning is particularly powerful for diverse learners. Students who struggle with long passages of text often thrive when given visual entry points. Neurodivergent learners, multilingual learners, and students with varied processing strengths benefit from flexible ways to represent knowledge.
Sketchnoting does not replace traditional notes—it expands them. A student might write a definition, then draw a quick icon beside it. They might map relationships using arrows or containers. They might visually chunk a lecture into sections using spatial layout. Each of these moves activates additional cognitive systems.
If you’d like to see how this connects to the research behind Dual Coding Theory, see this blog post. 
Try it with a short lesson. Give students permission to sketch as they listen. Compare recall and discussion depth afterward. The difference is often immediate.

We’ve all experienced it: you remember the layout of a page, a chart from a slide deck, or a diagram from a textbook long after you’ve forgotten the paragraph that explained it. That isn’t accidental. The brain is wired to process images differently than text.
While written language is processed sequentially—one word at a time—images are processed simultaneously. In a single glance, the brain can take in relationships, hierarchy, contrast, and spatial organization. That speed and integration matter when students are trying to make sense of new information.
Visual learning strengthens memory because it builds connections. When students pair a word with a symbol, a concept with a diagram, or a process with arrows and layout, they create anchors. Those anchors give the brain additional retrieval cues. Instead of searching for one verbal pathway, learners can access the idea through imagery, structure, and association.
This is one of the reasons sketchnoting works so effectively in the classroom. When students represent ideas visually—rather than simply copying them—they must decide what matters most. They simplify. They organize. They translate. That cognitive effort strengthens encoding.
Visual learning also supports conceptual understanding. A labeled paragraph about the water cycle is helpful. A diagram that shows evaporation rising, condensation forming, and precipitation falling creates a mental model. That model stays.
If you’re just beginning with visual strategies, you may want to explore the foundational tools in the first chapter or browse the full overview of Sketchnoting in the Classroom.
Even small shifts—adding icons, using containers, drawing arrows between ideas—can significantly increase retention. The goal isn’t artistic perfection. The goal is deeper processing.

If you’ve ever wondered why sketchnoting works so well for retention, the answer lives in cognitive science—specifically in something called Dual Coding Theory.
Dual Coding Theory suggests that we process and store information in two distinct systems: one verbal and one visual. When learners encounter information in both words and images, they create two pathways for remembering it. Those dual pathways increase the likelihood of recall and deepen understanding.
In classrooms, we often rely heavily on verbal input—lecture, reading, discussion, written notes. But when students pair a concept with a simple sketch, symbol, or diagram, they activate additional neural systems. Instead of recording information in a single channel, they build layered connections.
That’s where sketchnoting becomes more than “cute notes.” It becomes a research-aligned learning strategy.
Sketchnoting encourages students to translate ideas into visual representations. That translation process forces them to make meaning. They aren’t copying—they’re processing. And that processing strengthens memory, organization, and conceptual understanding.
This brain-based approach aligns directly with what we know about multisensory learning. When students listen, write, draw, and connect ideas simultaneously, they create richer cognitive networks. Even students who take strong traditional notes benefit from diagramming, symbolizing, or visually organizing the same content.
Below is a simple example of how Dual Coding Theory can look in action through sketchnoting.

To help you bring Dual Coding Theory into your classroom right away, I’ve created companion materials:

• A downloadable sketchnote infographic explaining Dual Coding Theory
• A ready-to-use template comparing verbal and visual learning strategies
• A visual vocabulary builder to help students sketch what they learn

These tools are designed to help you move from theory to practice—without overwhelming your planning time. Download the template, try it with your students, and see what happens when ideas move from words to images.
