The Visual Brain: Teaching That Clicks
“Writing could get into corners that other teaching tools couldn’t reach.”
— William Zinsser
I still remember one particular lesson years ago. I was explaining a concept with all the words I could think of—clear, logical, step by step. My students nodded politely, but I could tell from their eyes: nothing was sticking.
Then, almost instinctively, I drew a quick sketch on the board. The moment the image appeared, the room changed. Hands shot up, conversations sparked, and suddenly the concept wasn’t just understood—it was remembered. That day, I learned something powerful: sometimes one picture can do what a thousand words cannot.
IMAGES TRUMP WORDS
The brain processes visuals 60,000 times faster than text. Images aren’t just decorations on a slide—they’re shortcuts to understanding. They connect with emotions, trigger memory, and make abstract concepts concrete.
Long before humans wrote words, we told stories through drawings on cave walls. That hasn’t changed. Images reach the emotional part of the brain faster than text ever could.
A single image can inspire curiosity, stir empathy, or anchor a lesson in memory. Think of how a photo of a seed sprouting can spark more wonder than a paragraph describing growth.
Quick Tip: Swap one chunk of text in your next lesson for an image or visual metaphor. Let students interpret it before you explain. You’ll see how images invite imagination first, and understanding follows.
WRITING TRUMPS READING
Reading is passive. Writing, on the other hand, requires the brain to process, reflect, and reframe information in one’s own words. That act of producing rather than consuming turns knowledge into something learners own.
For example, instead of assigning a reading and moving on, ask learners to jot down three takeaways, sketch a quick diagram, or write one question they still have. Those small acts of writing deepen comprehension far more than silent reading ever could.
Quick Tip:
After sharing new content, pause and invite learners to write for just 60 seconds. Whether it’s a summary, a doodle, or a question, the act of writing helps them transfer knowledge from short-term to long-term memory.
When we lean on images and writing, we move from simply delivering information to shaping experiences that stay with learners long after the lesson ends. Words alone may fade, but a vivid picture lingers. Silent reading may pass quickly, but the act of writing roots ideas deeply in memory.
Teaching from the back of the room is really about trusting the brain’s natural design—leveraging what’s already wired into us: to see, to imagine, to create. When we honor this, our classrooms become places where learning doesn’t just happen—it sticks.
Do you want us to bring the Positive Discipline in the Classroom or Teaching from the Back of the Room training directly to your school or organization.
From leadership teams to full faculty, we offer customized workshops that equip educators to integrate SEL and Educational Neuroscience seamlessly into everyday teaching.
