The blurting method: how to do it, and when it beats flashcards

The blurting method is a revision technique where you read a section, close it, and write down everything you can remember on a blank page as fast as you can. Then you open the source, check what you wrote, and fill the gaps in a different colour. It works because writing from memory is retrieval practice, one of the two study techniques with the strongest evidence behind them. This guide covers how to blurt, how long to spend, whether it beats flashcards, the mistakes that turn it into copying, and how to run it on a board where the source sits next to your page.

What the blurting method is

Blurting is a staple of UK GCSE and A-level revision, and the name describes it: you blurt the topic onto paper. You choose a chunk small enough to hold in your head, such as one textbook subsection, one lecture or one page of a spec. You read it once with attention. Then you put it away and write: definitions, steps, diagrams, the example the teacher used, the word you half remember. Nothing has to be neat or in order.

The second half matters as much as the first. You open the source again and compare it line by line with your page. What you got right stays in black. What you missed or got wrong goes in a second colour. That coloured ink is your revision list, and the next blurt on the same topic should have less of it.

Is blurting a good way to study?

Yes, and the reason has a name. Psychologists call writing down what you remember from a text "free recall", and it is one of the standard ways of doing retrieval practice. Roediger and Karpicke had students either reread a prose passage or write out what they could recall from it. A week later, the students who had practised recall remembered 61 percent of the passage. The students who had reread it remembered 40 percent [1].

Karpicke and Blunt then set free recall against a technique that feels more thorough: building a concept map with the text open. A week later the free-recall group scored higher on both fact questions and inference questions, even though the map-builders rated their own learning higher [2]. Dunlosky and colleagues' review of ten study techniques rated practice testing as one of only two with high utility, and rated rereading and highlighting low [3]. A blurt is a practice test you write yourself.

Blurting only counts as retrieval if the source stays shut while you write. The moment you glance at it, you are copying, and copying feels productive for the same reason rereading does.

How to do blurting, step by step

1. Pick one chunkOne subsection, one lecture or one spec point. If you cannot read it in fifteen minutes, it is two chunks. Write the chunk's title at the top of a blank page so you know what you are trying to recall.
2. Read it once, properlyRead for understanding, not for memorising. Work out why each step follows from the last. If a sentence makes no sense, fix that now, because you cannot recall what you never understood.
3. Close it and blurtSource shut, phone away. Write everything you can remember, in any order: keywords, a rough diagram, the formula, the example. Keep going past the point where it feels empty, because the second wave of recall is where the effort pays. Stop when nothing new has come for a minute.
4. Check it in a second colourOpen the source and go through it line by line. Tick what you had. Add what you missed and correct what you got wrong in a different colour. Be strict: a vague phrase that would lose the mark in an exam counts as missed.
5. Blurt again, laterCome back to the same chunk in a day or two and blurt onto a fresh page without looking at the first one. The coloured gaps from last time are the test. When a chunk comes out clean twice on different days, move on and return to it a week later.

Most people skip the second blurt, and it does the most work. Study spread over separate sessions lasts longer than the same amount of study in one sitting: Cepeda and colleagues' synthesis of 254 studies found spacing ahead in nearly every condition they looked at [4].

How long should you blurt for?

For one chunk, about ten minutes of writing and ten of checking. If your page fills in two minutes, the chunk was too small or you blurted straight after reading, which tests your short-term memory more than your learning. If you are still writing after twenty minutes, split the chunk.

A useful rhythm for a revision session is read, wait, blurt: read a chunk, do something else for ten or fifteen minutes (another chunk, or a break), then blurt the first one. The delay makes recall harder, and effortful recall is what builds the memory.

Mistakes that make blurting useless

• Peeking. Even one glance turns the rest of the page into copying. If you are stuck, write a question mark and move on.
• Blurting straight after reading. Everything is still in your head for a few minutes, so the page looks great and you learn little. Put something in between.
• Skipping the check. An unchecked blurt can lock in the mistakes you made. The coloured corrections are half the method.
• Making it pretty. Blurts are rough by design. Time spent on headings and highlighters is time not spent remembering.
• Blurting the whole module at once. Ten pages of half-remembered keywords tell you nothing about where the gaps are. Keep the chunk small.

Blurting on a board

Paper works, and you need nothing else to start. A board helps with the two steps students find tedious: having the source to check against, and keeping every attempt.

In Bord, blurt into the notebook: type, sketch the diagram with the pen, or both, on a blank patch of an infinite board. For the check, you need the source beside your page. Drop your slides or chapter onto the same board as a source (that needs a free account), or ask Ask to lay out the topic in a section next to yours. Ask cites your file to the page, so every gap you mark points straight at where to reread. Scroll the reference out of view while you write, bring it back to check.

Next time, blurt on a fresh patch beside the old one, so you can see which gaps closed. When the same few facts keep turning up in your second colour, select them and ask Flashcards for a deck; misses come back in about ten minutes and the cards you know get spaced out. For the parts that need explaining, ask Quizbook for written questions, which it grades on the reasoning.
