Cognitive Load Theory in MedEdMENTOR's Web Design
Thinking less so you can think more
Behind the Curtain
Here at MedEdMENTOR, we constantly work to help you apply education theories and artificial intelligence to your real-world applications.
We present a new series where you can follow along as we do the same.
I want to delve into Cognitive Load Theory and how I applied its principles to improve the Theory Database page. The goal?
To make the site more user-friendly and informationally effective.
Cognitive Load and The Theory Database Page
Let's be honest, when we launched, our visual design was probably only 10% of where we wanted to be.

The Challenge: Navigating the Information Jungle
The digital age is a paradox: Never before has so much information been so readily available, yet it's easy to feel overwhelmed. Websites are no exception.
Too often, educational platforms are cluttered with a mixture of academic jargon, complex navigation menus, and inconsistent visuals.
(That is literally still MedEdMENTOR — for now!)
What is Cognitive Load Theory?
Originating from educational psychology, Cognitive Load Theory proposes that our working memory can handle only a limited amount of information at a given time. It breaks down the load into three categories:
- Intrinsic Load: The inherent difficulty of the content.
- Extraneous Load: The cognitive load generated by anything occupying attention that isn't part of the content.
- Germane Load: The cognitive load devoted to actually processing and understanding the material.

Understanding these categories helps us design experiences that make effective use of our cognitive resources.
Application of Cognitive Load Theory to Web Design
Let's break down the above improvements and why they're better. Our goal is to eliminate extraneous load, so that the brain can better manage the intrinsic load of the content itself.
Distinct Header and Body Sections
First, a distinct header (the part that says "Theory Database") was created that clearly separated it from the body of the site. This change reduces Extraneous Load by creating high-contrast. Stark differences in appearance make it easy for the brain to process that the header is separate from the content.
Minimized Text and Consistent Formatting
The next step involved removing extraneous text and ensuring formatting consistency. By reducing the volume of text, we further reduce the Extraneous Load of each page.
With our improved version, you just don't have to think as hard when you navigate.
(Note that we cut out extraneous text, not all the text — a fine line)
Actionable Items and Affordances
Finally, actionable items were clearly highlighted. For example, actionable cards get a shadow while the header does not. This immediately tells the user where their attention is most needed, freeing up cognitive resources for deeper understanding and engagement.
Why Theory Matters
Just like in our previous discussions about using a theory-based approach to tackle problems in AI and HPE (Beyond Basic Science: Why Medical Education Theory Matters, AI in Medical Education: A Theory-Based Approach) applying Cognitive Load Theory to web design means we're not just making random changes. Each modification is backed by theoretical understanding and aims to make a genuine impact on how users engage with the platform.
Building on Theory
In implementing these changes based on Cognitive Load Theory, we are adding to the growing body of research on how this educational theory can be adapted to various platforms, including digital ones.
So the next time you find yourself effortlessly navigating MedEdMENTOR, remember—there's some serious educational theory working in the background to make your learning experience as efficient and effective as possible.
(And next time you encounter a section that's not redesigned yet, know that we're applying our intrinsic load to helping you out!)
That's all for now. Keep an eye out for future articles where we'll dive deeper into other educational theories and their practical applications. And look out for more visual design improvements!
