Understanding Cognitive Load Theory
How understanding cognitive load can help you design better learning experiences for yourself and others.
Dr. Emily Watson
Cognitive Load Theory, developed by John Sweller in the 1980s, provides a framework for understanding how our brains process and store information during learning.
The Three Types of Cognitive Load
Intrinsic Load: This is the inherent difficulty of the material itself. Some concepts are simply more complex than others.
Extraneous Load: This is the unnecessary cognitive effort caused by poor instructional design. Confusing layouts, irrelevant information, or unclear instructions all contribute to extraneous load.
Germane Load: This is the productive cognitive effort used to process and understand the material. This is the type of cognitive load we want to maximize.
Applying Cognitive Load Theory
Understanding these principles can help you design better learning experiences. Focus on reducing extraneous load by simplifying presentations and removing distractions, while ensuring the material is challenging enough to promote germane processing.
