Brain Dump

The strategy, as published

Why you might use it

The problem it may help with

Most revision defaults to putting information back in front of pupils: re-reading, highlighting, copying notes. The research in this guide points the other way. Retrieval, getting knowledge out, does more for long term memory than another pass over the page.

A brain dump is the simplest possible version of that. It needs no preparation, no question writing and no technology, and it gives you something a quiz cannot: a picture of what pupils reach for unprompted, and in what order.

What it might look like

One version of it, in a classroom

Two lessons into a new topic, a class gets a blank page and two minutes: write everything you remember about last lesson. No notes, no talking. Afterwards, pupils open their books and check what they missed. The teacher asks for one thing that did not come back, and the answers shape the start of the next lesson.

Try it

A way to begin

End one lesson this week with it. Two minutes, blank page, everything you remember from today. Keep it out of any book you mark; the point is the retrieval, not the record.

What to notice

Reading what happens

• What most of the class could not recall. The card says it plainly: that is precisely where teaching needs to return.
• Who writes steadily and who freezes at the blank page. Freezing is information too, and cued recall is a gentler step back.
• Whether what comes back is what you would have predicted. It often is not.

Things to think about

Before and while you use it

• There has to be something to retrieve. If the material was only met once, a brain dump measures the teaching more than the pupils.
• The imperfect attempt is the point, so resist tidying it into a marked task. The moment it carries stakes, pupils play safe and you lose the honest picture.

Where this connects

• 📄 Closed-Book Reconstruction Students reconstruct key ideas from memory, then open notes and correct in a different colour. Karpicke and Blunt found this outperforms re-reading. The corrections are the data. 01 Retrieval Practice · The Testing Effect
• 🔔 Cued Recall Tulving and Thomson showed retrieval depends on available cues. A heading, a keyword, labels removed: each triggers retrieval without doing the work. Builds confidence before unaided retrieval. 01 Retrieval Practice · Retrieval Formats
• 🧠 Retrieval Beats Re-reading Replace re-reading with retrieval. Instead of reviewing notes, ask students to write down everything they remember, then check. The testing is the learning, not the preparation for it. 01 Retrieval Practice · The Testing Effect
• 🌧️ The Muddiest Point At lesson close, each student anonymously writes the one thing they are least clear about. The teacher addresses the most common muddy points publicly at the start of the next lesson. Two minutes; high value. 02 Formative Assessment · Students as Owners of Their Learning

Technology second

Where technology fits

Paper does this job perfectly well. Where the approved shared document or whiteboard tool in your setting adds something is speed of reading: thirty attempts visible at once, skimmable for the gaps, without collecting a single book. The retrieval effort is the important part, not the admin around it.

The wider thinking

Where the evidence sits

This sits squarely in the testing effect tradition: Roediger and Karpicke showed that the act of retrieving is itself a learning event, not just a measure of one. The card’s attribution stands as published: Roediger; Karpicke; Agarwal.
