Look, Cover, Write, Check (LCWC) is a four-step study technique widely taught in UK primary schools for learning spellings — but it is just as effective at secondary level for memorising key terms, definitions, formulae, vocabulary in modern foreign languages, and precise scientific language. Its power comes from the "Write" step, which forces active retrieval rather than passive recognition.
What is the Look, Cover, Write, Check technique?
The four steps are:
- Look: Study the term or piece of information carefully. Do not just glance — take ten to fifteen seconds, read it aloud, note any tricky parts or patterns.
- Cover: Hide the original completely. Use your hand, a piece of card, or fold the page.
- Write: Without looking, write the term, definition, or information from memory. Do not lift the cover to check — produce what you can retrieve unaided.
- Check: Reveal the original and compare it letter by letter, word by word. Mark what you got right. Note precisely what you got wrong — a missing word, a misspelling, a gap in the definition.
Repeat the cycle immediately for anything you got wrong, and return to the whole set again after 24 hours.
Why does this technique work?
The key is the Cover → Write sequence, which is a form of retrieval practice. When you cover the information and attempt to recall it, you are exercising exactly the same cognitive process as in an exam — retrieving from memory under conditions where you cannot see the answer. This is fundamentally different from re-reading or highlighting, where you can recognise the information without truly remembering it.
The Education Endowment Foundation consistently identifies retrieval practice as one of the highest-impact, lowest-cost study strategies available. LCWC applies retrieval practice in a structured, manageable format that works for small, discrete pieces of information.
What can I use Look, Cover, Write, Check for beyond spellings?
| Subject | What to LCWC | Example |
|---|---|---|
| Biology | Key term definitions | Look: "Osmosis — the net movement of water molecules from a region of higher water potential to a region of lower water potential through a partially permeable membrane." Cover, Write, Check. |
| Chemistry | Equations and formulae | Look: "Photosynthesis: 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂." Cover, Write, Check. |
| French / Spanish / German | Vocabulary lists | Look: "se souvenir = to remember." Cover, Write, Check. |
| History | Key dates and events | Look: "1066 — Battle of Hastings, William the Conqueror defeats Harold II." |
| Geography | Key terms | Look: "Urbanisation — the increase in the proportion of people living in towns and cities." |
| Maths | Formulae | Look: "Area of a circle = πr²." Cover, Write, Check. |
| English Literature | Quotations | Look at the quotation; cover it; write it from memory; check every word. |
How do I run a productive LCWC session?
- Prepare a list of the items you want to learn. Write each item clearly on the left half of a page, leaving the right half blank for the "Write" step.
- Work through the list once, completing all four steps for each item in turn. Do not skip the "Check" step.
- Mark your errors precisely. Do not just mark a whole item as wrong — identify exactly which word or part of the definition you missed.
- Run a second cycle immediately for every item you got wrong. Repeat until you get it right once.
- Return to the full list the next day for a spaced review.
An LCWC session for twenty key terms in biology takes roughly fifteen to twenty minutes for the first cycle, and ten minutes for items you need to repeat.
How does LCWC differ from a flashcard?
Flashcards and LCWC both use retrieval practice, but they work slightly differently:
- Flashcards test in a question–answer format (front = prompt, back = answer) and work best with the Leitner or spaced repetition system to schedule reviews.
- LCWC is ideal for verbatim recall — spellings, formulae, precise definitions, exact vocabulary — where you need to reproduce the information word for word, not just recognise the concept.
For a definition where precision matters (as in GCSE science mark schemes, which often require specific terms), LCWC's word-by-word checking enforces a standard that flashcard "self-grading" sometimes lets slip.
Frequently asked questions
How often should I repeat Look, Cover, Write, Check for the same item?
Repeat a specific item until you can write it correctly three times in a row without errors. Consecutive successes are a better indicator of learning than total attempts. After three consecutive correct recalls, space your next review by two to three days, then a week, and so on.
Can I use LCWC for long exam quotations?
Yes, with a modified approach. Break the quotation into chunks of five to eight words and master one chunk before moving to the next. Then practise running the chunks together as a complete quote. Trying to memorise a twelve-word quotation in one go is much harder than building it in three segments. This is the same chunking principle used to memorise long phone numbers.
Is LCWC worth using if I already do flashcards?
Yes — they complement each other. Use flashcards (with spaced repetition) for your main revision across all topics. Switch to LCWC specifically for items where you need verbatim accuracy: the exact wording of a science definition, the chemical formula, the precise spelling of a technical term that costs marks when misspelled in an exam.
Should I use LCWC on paper or could I do it on a screen?
Paper works better. When you write by hand, the physical act of forming each letter is a separate cognitive decision, which means errors are immediately obvious in a way that typing does not always reveal. Many students also find that handwritten practice is closer to the pen-on-paper experience of an exam itself.
