Zorg SpaceDoes testing yourself work better than rereading?
Short answer
Yes. Retrieving information from memory — testing yourself — strengthens it more than reading it again, even when the test feels harder and you get some answers wrong. Rereading creates a comfortable feeling of familiarity that is easy to mistake for knowing. Testing reveals what you actually know, and the act of recalling makes it easier to recall next time.
This is one of the best-documented findings in learning research, often called the testing effect or retrieval practice.
The research in brief
In a widely cited study, Roediger and Karpicke (2006) asked students to learn short prose passages. Some reread the passages; others read them once and then practised recalling them. On a test five minutes later, the rereading group did slightly better. But on tests two days and one week later, the group that had practised recall remembered substantially more.
The pattern — rereading wins in the short term, testing wins in the long term — explains why rereading is so popular: it looks better right after studying, which is exactly when learners judge their own progress.
A large review of study techniques (Dunlosky and colleagues, 2013) rated practice testing as one of the two most effective techniques, alongside spacing.
Why rereading feels so good
When you reread a text or a word list, everything looks familiar — and familiarity feels like knowledge. But recognising something on the page is much easier than producing it without the page. Researchers call this an illusion of competence. Self-testing removes the illusion: either the answer comes, or it does not.
Ways to test yourself in a language
| Method | How |
|---|---|
| Cover the translation | read the target word, say the meaning; then the other way round |
| Flashcards | recall before flipping; rate honestly |
| Blurting | after a grammar lesson, close it and write down everything you remember |
| Back-translation | translate a short text into your language, then back into the target language, and compare |
| Gap-fill | delete key words from a text you studied and fill them in the next day |
| Explain the rule | explain a grammar rule out loud as if teaching someone, with your own examples |
| Dictation | listen to a sentence and write it down; check against the text |
| Retelling | after reading or listening, retell the content without looking |
Feedback matters
Testing works best when you check your answers. Recalling something wrong and never correcting it can strengthen the error. Always look at the correct answer after trying — especially for the items you got wrong.
Combine testing with spacing
Testing and spacing reinforce each other. Test yourself today, again in a few days, then in a week or two. Each successful recall after a gap strengthens the memory more than a recall straight after studying.
How to change your study habits
- After every lesson, spend the last five minutes recalling it without looking.
- Replace “read through my notes” with “write down what I remember, then check”.
- Turn new vocabulary into cards with the meaning on the front at least some of the time.
- Accept that testing feels harder — that difficulty is part of why it works.
In short
- Self-testing strengthens memory more than rereading in the long run.
- Rereading feels better because familiarity looks like knowledge.
- Test in many ways — cards, blurting, gap-fills, retelling, dictation — and always check the answers.
- Combine testing with spacing for the strongest effect.
