Cognitive Load Theory — Designing Training That Sticks

In this episode of the JuvoHub Podcast, host Jonathan Saar continues his Learning Theory Series by breaking down cognitive load theory—a major framework that helps educators understand how much information learners can reasonably process at once. He explores intrinsic, extraneous, and germane load, and discusses how instructional designers can transform complex “brain dumps” from subject matter experts into learner-friendly training.

Some main highlights include why clarity, structure, and real-world application matter far more than simply presenting information. Jonathan also shares questions educators should ask themselves when evaluating whether a course is overwhelming learners and how to refine material for stronger retention.

Whether you design online courses, teach live classes, or guide teams, this discussion offers practical insights to improve training effectiveness.

👉 TLDR: Cognitive Load Theory teaches that simplifying, clarifying, and sequencing information leads to better learning—and “less is more” when it comes to instructional design.

The Core Takeaway: Why Simplifying Content Strengthens Learning

Cognitive Load Theory reinforces an essential principle for educators: training isn’t about delivering everything you know—it’s about designing information in a way that learners can process, connect, and retain. By reducing unnecessary complexity and focusing on clarity and application, educators create training that truly supports long-term understanding. As you move forward in your teaching or instructional design work, remember that impactful learning often comes from simplifying, not adding more.
