John Sweller

John Sweller is an educational psychologist best known for his work on Cognitive Load Theory. This theory suggests that our brains have a limited capacity for processing information, and learning is most effective when this load is managed carefully. Sweller argues that instructional design should consider the mental effort required to understand new information, minimizing unnecessary complexity to enhance learning. By structuring materials in a way that supports cognitive load management, educators can help students learn more efficiently, fostering deeper understanding and retention of knowledge. His research has significant implications for teaching methods and curriculum development.
