Interleaved Practice
Mix related topics or problem types to improve transfer.
Explanation
Most people practice by focusing on one skill at a time (blocking) because it feels more organized and shows immediate improvement. But interleaving—mixing different types of problems or skills within the same session—creates deeper learning. It forces your brain to constantly distinguish between different situations and choose the right approach.
Real-World Example
Math: Instead of 20 algebra problems, then 20 geometry, mix them. Students score 43% higher on tests. Baseball: Hitting random pitches improved batting average more than predictable ones. Musicians: Mixing pieces improves performance more than perfecting one at a time.
How to Apply
Don't complete one topic before moving to next. Mix related skills in same session. Change up every 10-15 minutes. Random is better than predictable. Yes, it feels harder—that's the point. Harder practice = easier performance.
