Episode notes
Why Learning Can Be Effortful
- Learning is hard because our working memory has limited capacity for new info, but no limit for mastered knowledge.
- Evolution predisposes us to learn some skills naturally, while others require effortful learning due to novelty.
Three Types of Cognitive Load
- Cognitive load theory divides cognitive demand into intrinsic, extraneous, and germane loads.
- Germane load, while effortful, enhances learning by deepening memory and is beneficial when capacity allows.
Power of Worked Examples
- Worked examples help learners avoid the extraneous load of problem-solving and better grasp general solutions.
- Practice without solutions is suitable only once patterns are well understood and facilitates retrieval effort.
