Kolina explains how understanding memory improves education, focusing on two key strategies. **Spaced practice** involves distributing study over time, like reviewing material across days, which is better for long-term memory than cramming. **Retrieval practice** means actively recalling information, such as through quizzes, which is more effective for learning than just rereading. Both methods make learning feel harder at first, but research shows they significantly improve long-term retention and understanding across different subjects and ages. Teachers can combine these techniques to help students learn more effectively.
