Sweller, John

John Sweller is an educational psychologist best known for developing Cognitive Load Theory. This theory focuses on how the human brain processes and learns information. Sweller argues that our working memory has limited capacity, so learning is most effective when we manage cognitive load—essentially, the amount of information we take in at one time. He emphasizes the importance of structured learning and instructional design that considers these cognitive limits, helping educators create environments that enhance understanding and retention of complex concepts. This approach has significant implications for teaching methods and educational materials.
