Flashcards are the most studied learning tool there is, and the reason they work is not repetition — it is retrieval. Being asked a question and having to pull the answer out of your head does more than reading the same fact five times.
Which means the card has to ask something. A card that shows you the answer alongside the question has quietly become a reading exercise.
1. Write the front text
The Front text field takes your items, one per line. What goes on the front is the prompt; the back holds what the learner is trying to recall.
The most common mistake is putting too much on the front. A card asking 'the French Revolution: causes, key dates and outcomes' is not a flashcard, it is an essay question. Split it into four.
| Weak card | Better |
|---|---|
| Photosynthesis | What gas do plants take in during photosynthesis? |
| 1789 | What began in France in 1789? |
| Le chien — the dog | le chien → ? |
The pattern is the same each time: a question with one answer, not a topic.
2. Set the border
The Border setting draws the cut line. Turn it on for anything you will cut by hand — a visible line is the difference between a stack of neat cards and a stack of slightly wonky ones.
If you are cutting with a guillotine, a border is optional. If children are cutting them out, make it heavy.
3. Print and cut
Two practical notes that save a reprint:
- Print on the heaviest paper your printer takes. Thin paper shows the answer through the card, which defeats the purpose entirely.
- Print one page, cut one card, and check it before printing thirty.
That first one catches people out constantly. Hold a printed card up to a window before committing to a set.
4. How to use them so they work
The technique that makes the difference is spacing: review a card, and if you get it right, do not review it again tomorrow — review it in three days, then a week, then a fortnight. Cards you get wrong come back the next day.
Three boxes and a rubber band does this well enough. The point is that easy cards stop taking up time, which is what lets a deck grow past fifty without becoming a chore.
For vocabulary specifically, cards test recall but not spelling. Pair them with a missing letters sheet if writing the word correctly matters — the two exercises train different things.
