Trying to recall from memory strengthens learning more than re-reading.

Reviewing over increasing intervals to resist forgetting.

Mixing related topics/problem types to improve discrimination and transfer.

Explaining why/how in your own words; linking new ideas to what you already know.

Effortful practice that is still solvable tends to improve long-term retention.

Practice tests improve retention more than additional study of the same material.

Producing an answer yourself improves memory more than reading the answer.

Combining words and visuals improves recall when both are meaningfully linked.

Grouping items into meaningful units reduces working-memory load.

You can hold only a few items at once; reduce load to think better.

Total mental effort; simplify presentation so effort goes to learning, not decoding.

Learning is stronger when you can apply knowledge in new contexts, not just repeat.

Practice across different contexts and examples to improve flexibility.

Fluency from re-reading feels like learning.

Fix: test yourself.

Knowing what you know (and do not) helps you choose better study strategies.

Fast feedback helps skill acquisition; delayed feedback can strengthen retention.

Making mistakes and correcting them can improve learning if feedback is clear.

Similar memories compete (proactive/retroactive). Spacing and contrast reduce it.

Memory is better when retrieval context matches learning context.

Environment cues can aid recall; vary contexts to reduce dependency.

Sleep helps stabilize and integrate memories; it is part of learning.

Extra practice after mastery can help durability, but has diminishing returns.

Explain simply; gaps in explanation reveal gaps in understanding.

Recognition (seeing the answer) is easier than recall; train recall.
