What duffspin is designed to fix
Duffspin is a short retrieval routine for vocabulary that has already been introduced, not a first-teach activity. It targets the gap between recognising a word on a page and producing it under mild time pressure. In a typical GCSE French class, ten to twelve minutes once a week is enough to expose which words are stable and which have quietly dropped away.
Why the routine uses mixed recall rather than single-word lists
The core mechanism is interleaving: students move between French to English, English to French, and a short sentence completion in one cycle. That prevents the common false confidence that comes from reading a list in the same order every week. A student who can translate “brouillard” in isolation but cannot place it in “Il y a du brouillard ce matin” has a recognition habit, not a usable word.
How to run a 12-minute duffspin session
- Set the pool. Choose 20–24 items from the last three weeks, not the whole term. Include nouns, verbs and one or two connectives so the recall is not grammatically flat.
- Do three fast passes. Pass one is French to English; pass two is English to French; pass three is a cloze sentence with the target word removed. Keep each pass to three minutes.
- Mark only errors and hesitations. A correct answer produced after six seconds is not the same as an instant one. Students mark hesitations with a dot and errors with a cross.
- Re-test the marked items immediately. The final three minutes are spent only on the dotted and crossed items, spoken aloud in pairs. This closes the loop before the lesson ends.
For a clear model of the routine, this duffspin guide from Dragon Tutors sets out the teach-test-correct-repeat cycle in plain terms; it is useful for departments that want a consistent script rather than another worksheet.
What to adjust after four weeks
- If hesitation dots cluster on verbs, add a tense cue to the English prompt, such as “to go — future” rather than just “to go”.
- If errors are spread evenly, reduce the pool to 16 items and increase the final re-test to four minutes. Duffspin works through repetition of the missed set, not through volume.
- If students finish early, add a spoken extension: one student gives a sentence with the target word and the partner identifies the word. This adds production without lengthening the written cycle.
How to judge whether duffspin is working
The useful signal is a falling hesitation rate on the same item across two weeks, not a rising score on a one-off test. Keep the marked duffspin sheet and compare the dotted items. If a word is still dotted after three exposures, it needs a different prompt — a collocation, a picture or a pronunciation cue — rather than a fourth identical drill.
