Key idea: Strategies based on how memory works can improve it. Recalling information beats reading it again.
Ways to improve memory
Retrieval practice
Testing yourself strengthens the path back to a memory.
Spacing
Spreading study over days works better than cramming.
Context cues
Going back in mind to the place and feelings of an event helps recall.
Recall · Space · Cue
Roediger and Karpicke (2006) had students study a passage four times, or once and then recall it three times. A week later, the recall group remembered 61% against 40%.
Go further: higher-level insight: Re-reading feels easier and students expect it to work better. The feeling of learning is not the same as learning.

Key idea: Strategies based on how memory works can improve it, and some are tested in real settings.
Strengths
- Large, repeated effects
- Cheap and easy to use
- Based on memory research
Limitations
- Lab passages and staged events
- Needs effort and practice
- Some strategies raise errors
A strategy is strongest when it has been tested outside the laboratory, with the people who will use it.
Watch out: Explain why it works. Link the strategy to how memory works, not only to the result.
