Concept Mapping from Memory

The strategy, as published

Why you might use it

The problem it may help with

The qualifier carries the strategy. Concept mapping with the notes open is an organising task; concept mapping from memory is retrieval, and Karpicke and Blunt found it outperformed re-reading for retention.

It also retrieves something a quiz rarely touches: the connections. Not just what students know but how the ideas relate. As the card has it, relational knowledge beats isolated facts.

What it might look like

One version of it, in a classroom

Closing a unit on ecosystems, pupils get a blank page and one instruction: map the topic from memory, ideas in boxes, relationships written on the lines between them. Books stay shut. Afterwards they compare maps in pairs and add missing links in another colour.

Try it

A way to begin

Run one from-memory map at the end of a current topic. Ask for the connecting lines to be labelled; an unlabelled line is a relationship nobody has had to retrieve.

What to notice

Reading what happens

• The links, more than the boxes. Missing ideas show gaps in knowledge; missing links show gaps in how it fits together.
• Whether maps improve across the year. Mapping is itself a skill, and early attempts will understate what pupils know.

Things to think about

Before and while you use it

• The from-memory condition is the mechanism, so resist the merciful instinct to allow a peek at the notes. Checking comes afterwards, as its own step.

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
• ✍️ Brain Dump A blank page, two minutes, no notes: write everything you remember. The imperfect attempt is the point. What students cannot recall shows precisely where teaching needs to return. 01 Retrieval Practice · The Testing Effect
• 💬 Retrieval Beyond Facts Factual retrieval builds the schema; higher-order retrieval tests whether students can use it. Secure the foundations first, then push beyond them. Retrieval is not a pub quiz. 01 Retrieval Practice · Retrieval Formats
• 🔀 Vary the Retrieval Context Retrieve the same content in different formats and settings, decontextualising knowledge so it is not tied to one context or format. Harder for students; that is precisely the point. 01 Retrieval Practice · Desirable Difficulties

The wider thinking

Where the evidence sits

Karpicke and Blunt's study is the direct source, and it belongs to the broader testing effect tradition established by Roediger and Karpicke. The card’s attribution stands as published: Karpicke & Blunt.
