Revision Cards vs Mind Maps for KS3: Which Works Better?

Revision cards and mind maps are both useful KS3 revision tools, but they do different jobs. Revision cards train active recall through self-testing; mind maps build an overview of a topic. Used together in the right order, they are more powerful than either used alone.

What are revision cards and why do they work?

A revision card — also called a flashcard — has a question or prompt on one side and the answer on the other. The key is what happens when you use them: you try to recall the answer before flipping the card. That act of retrieval, rather than re-reading, is what makes them effective.

This technique is called active recall or retrieval practice. The Education Endowment Foundation (EEF) — an independent charity that reviews what the evidence says about learning — rates retrieval practice as having high evidence of impact for improving long-term memory. Put simply, every time you successfully pull a fact from memory, you make it easier to recall next time.

Revision cards are particularly effective for:

Vocabulary and definitions (e.g. key terms in science or geography)

Dates and events in history

Mathematical formulae and rules

Foreign language vocabulary

Quotations in English literature

Making the cards is itself a revision activity, because writing out a question and answer forces you to think about what matters most.

What are mind maps and when do they help?

A mind map is a visual diagram that starts with a central topic in the middle of the page, then branches outwards into subtopics, and branches again into supporting details. The structure mirrors the way ideas connect rather than listing them in a linear order.

Mind maps are most useful for subjects where ideas link to each other in complex ways — biology (body systems connect), history (causes lead to events lead to consequences), geography (human and physical factors interact). Drawing a mind map helps a student see the shape of a topic and understand how pieces fit together before trying to memorise individual facts.

What mind maps are less good at is testing memory. You can look at a completed mind map and feel like you know the content — but feeling familiar is not the same as being able to recall it independently. That is why mind maps work best as a starting point, not a finishing point.

How do the two techniques compare?

Feature | Revision Cards (Flashcards) | Mind Maps
What they involve | Question on one side, answer on the other | Central topic with branching subtopics
Best for | Facts, definitions, formulae, vocabulary | Overview, connections, structure
Type of thinking | Active recall — testing yourself | Organising and linking ideas
Evidence base | High (EEF rates retrieval practice as strong) | Moderate — useful for overview; weak alone
Good for exams? | Very good — mirrors the challenge of answering questions | Helpful early in revision; less so close to exams
Making them is revision? | Yes — writing forces prioritisation | Yes — drawing forces organisation
Easy to do without resources? | Yes — paper or free apps | Yes — paper or digital tools
Best subjects | Maths, science, languages, history (dates) | Biology, history, geography, English themes

What does the research say?

The EEF's Teaching and Learning Toolkit rates retrieval practice — the technique that revision cards rely on — as having high impact on learning, based on strong evidence across a wide range of studies. Spacing out retrieval practice over time (returning to cards you got wrong, leaving correct ones for longer) amplifies the effect further. This is called spaced practice and is also rated highly by the EEF.

Mind maps on their own feature in many schools as a revision tool, but the research suggests they are most effective when used as an organisational tool before retrieval practice, rather than as a standalone strategy. Passive re-reading of a mind map — just looking at it — is a much weaker strategy than self-testing.

The takeaway for KS3 students and their parents: mind maps are a useful first step. Revision cards are the engine room.

What is the best way to use both together?

The most effective revision approach for KS3 combines both tools in a sensible order:

Start with a mind map at the beginning of a revision session for a topic. Draw it from memory — do not copy from your notes. Identify the gaps (blank branches) — those are the things you need to learn.

Fill in the gaps by returning to your notes, textbook, or BBC Bitesize for the missing information.

Make revision cards for the specific facts you need to memorise from that topic — dates, definitions, formulae, key terms.

Test yourself using the revision cards over the following days. Get someone at home to quiz you, or go through them alone.

Space it out — revisit the same cards a few days later, then again after a week. Each time you successfully recall an answer, you strengthen that memory.

This approach means you understand the bigger picture (mind map) and can recall the specific details under pressure (revision cards), which is exactly what KS3 and GCSE assessments test.

Frequently asked questions

Are revision cards better than mind maps for KS3?

For building memory and preparing for tests, yes — revision cards (flashcards) are generally more effective because they use active recall. Mind maps are excellent for organising your thinking and understanding how ideas connect, but they do not directly train you to retrieve information under exam conditions. Use mind maps first, then make cards and test yourself.

How many revision cards should a KS3 student make per topic?

There is no perfect number, but between 10 and 30 cards per topic is a sensible target for most KS3 subjects. Focus on cards for facts your child finds difficult to remember — not everything needs a card. If a card is consistently answered correctly, set it aside and focus on the ones that still cause hesitation.

Can my child use apps instead of paper cards?

Yes — apps such as Anki or Quizlet let students make digital flashcards and use spaced repetition algorithms to show cards at the right intervals automatically. BBC Bitesize also has built-in quiz tools for many KS3 subjects. Whether paper or digital works better depends on the student; the important thing is that they are actively testing themselves, not just reading through notes.

Do mind maps count as active revision?

Drawing a mind map from memory — starting with a blank page and trying to recall the structure of a topic — is active revision and is more effective than copying a mind map from a textbook. However, simply re-reading a completed mind map is passive and relatively weak as a revision technique. Encourage your child to test themselves by redrawing mind maps from scratch, then checking for gaps.
