Learning how to learn: Methods that really work

In short: Active recall, spaced repetition and understanding instead of re-reading are the best-supported ways to retain knowledge permanently.

In more detail: Many people learn by highlighting, copying out and re-reading. This feels productive but achieves less than expected. Learning research names more effective strategies that can be used without great effort at school, vocational school and exam preparation.

In Depth

Active recall (retrieval practice)

Instead of re-reading the material, test yourself: close the book, write down or say aloud what you know, then compare. Flashcards, practice questions and mock exams use this testing effect: remembering itself strengthens memory more than taking it in again.

Spaced repetition

Several short sessions spread over days and weeks are better than one long night before the exam. Review just before forgetting: after 1 day, 3 days, 1 week, 2 weeks. Flashcard software (Anki) and platforms with a review schedule plan the intervals automatically.

Understanding and connecting

• Explain: explain the material in your own words (Feynman method), even to an imaginary person or a rubber duck.
• Examples and application: solve problems, build a small program, apply what you learned in practice.
• Connect: draw mind maps, look for connections to what you already know.
• Interleaved practice: mix task types instead of block by block.

Organisation and habits

• Short sessions: 25 to 45 minutes focused, then a break (Pomodoro).
• Switch off distractions, keep the phone out of reach.
• Sleep consolidates what you learned; exercise and water help concentration.
• A fixed study plan with goals per week.
• Difficult things first when you are fresh. What works less: pure highlighting, re-reading several times, multitasking while learning and the feeling “I already know this”.
