Cover-Copy-Compare

A three-step self-testing loop: look at the word and its definition; cover both; write them from memory on the right side of the page; compare with the original. If wrong, repeat before moving on. Five words at a time, and the learner can run the whole procedure alone at their desk, without a teacher, without a partner, without a device.

Procedure

1. Prepare a two-column sheet. Left column holds target items — the word, plus a short definition or example sentence (a list of 5–10 items per sheet is ideal).
2. Look: Learner studies the first item for 5–10 seconds, silently saying the word and its meaning.
3. Cover: Cover the left column with an index card, a folded paper strip, or a hand.
4. Copy: On the right side of the sheet, write the word and its definition from memory.
5. Compare: Uncover the original. Self-check. If the reproduction is accurate, tick the item and move on. If any element is wrong, re-study and run the cycle again for that item before continuing.
6. Work through the whole list. At the end, circle the 2–3 items that needed repetition — those become the seeds for the next session.

Why it works

Cover-Copy-Compare has one of the strongest evidence bases of any individual vocabulary technique. Joseph et al.'s (2012) meta-analysis of 18 studies across spelling, vocabulary, and content-area learning found consistent moderate-to-large effects, and the procedure has been endorsed by the NYS RtI framework as an evidence-based intervention. The mechanism combines three research-supported principles: active recall (the copy step is retrieval, not reading), immediate feedback (the compare step, which Hattie's meta-analyses rank among the most powerful influences on learning), and distributed repetition (incorrect items cycle back, correct items advance — a micro-Leitner inside a single session).

Classroom use

CCC is designed for individual self-study, which makes it an ideal ten-minute closer or homework opener. But it can be staged in class too:

• Silent CCC block: Ten minutes before a vocabulary quiz. Every learner works through their personal card set.
• Partner CCC: Pair A's list; Pair B watches the compare step to flag errors the self-checker might miss. Occasional peer oversight catches the habit of "close enough" self-marking.
• Rolling CCC notebook: The personal notebook has a two-column layout. New words accumulate in the left column over the week; the right column is always blank and always used.

Tips

• The technique is only as good as the left-column material. Garbage-in — vague definitions, unclear examples — produces garbage-out self-testing.
• Teach learners explicitly that errors are the signal, not a failure. Items that repeat are where learning is actually happening.
• Combine with Spaced Retrieval: items learners mark as "needed repetition" today go to the front of tomorrow's list, not into the general pile.
