Concept maps for A-level revision: links, not lists
Meta-analytic evidence that node–link diagrams support retention and transfer
Concept maps are diagrams: concepts as nodes, relationships as labelled links. Building them forces you to decide how ideas connect — deeper processing than copying bullet points. They work across sciences, psychology, and other A-level subjects where topics aren’t isolated.
Evidence
Nesbit & Adesope (2006) meta-analysed dozens of studies (thousands of learners): use of concept and knowledge maps was associated with gains in knowledge retention and transfer, with effect sizes varying by how maps were used (constructing often beats only viewing).

How to build one that earns marks
- Start from the exam question’s theme, not the textbook’s order
- Use link labels: causes, limits, compares to, requires evidence from…
- Colour-code AO1 vs AO3 chains if that helps you see depth
- Rebuild the map from a blank page weekly — the construction is the learning
A beautiful poster you copy from a textbook is decoration. A messy map you build from memory is revision.
