A concept map is a diagram of ideas and the relationships between them. Where a list of highlights or a linear outline leaves the connections implicit, a concept map spells them out: this idea grounds that one, this concept is a kind of another, this causeleads to that effect. The labels on the lines carry as much meaning as the boxes.
It is also a plain way to test whether you understood what you read. This guide walks through what a concept map is, how it differs from a mind map, and a method for building one that you can repeat on any subject.
What Is Concept Mapping?
Concept mapping was developed by researcher Joseph Novak in the 1970s as a way to represent what students understood about a topic. The core unit is the proposition: two concepts joined by a linking phrase that forms a short, meaningful statement.
- Concepts are the nouns: the ideas, objects, or events you are studying.
- Linking phrases say how two concepts relate: "causes," "requires," "is replaced by," "grounds."
- Propositions are the sentences the two make together, read along the line.
A good concept map reads like a network of short sentences. If you can't read a clear statement off a connection, the connection isn't finished.
Concept Map vs Mind Map: What's the Difference?
People use the terms interchangeably, but they are different tools:
| Concept Map | Mind Map |
|---|---|
| A network: ideas connect in any direction | A tree: everything branches from one center |
| Links are labeled with relationships | Links are usually unlabeled branches |
| Shows how concepts relate to each other | Shows how subtopics belong to a topic |
| Best for understanding structure and cause-and-effect | Best for brainstorming and note capture |
Mind maps are good for getting ideas out of your head fast. A concept map is the better tool when you want to understand how the pieces of a system push on each other.
How to Build a Concept Map (Step by Step)
Step 1: Pick a Focus Question
A concept map should answer a specific question, like "How does inflation affect employment?" or "What makes a system self-regulate?" The question keeps the map from sprawling into everything you know.
Step 2: List the Key Concepts
Brainstorm 10 to 25 concepts relevant to the question. Keep each one to a short noun phrase. Leave them unconnected for now.
Step 3: Rank From General to Specific
Rough out a hierarchy. The broadest, most inclusive concepts go near the top or center, and the specific examples and instances sit further out. This gives the map a readable shape.
Step 4: Connect and Label
Now draw the links. This is the step that tests what you know: for every connection, write the linking phrase that makes it a statement. "Interest rates → influence → borrowing." If you cannot name the relationship, you do not understand it yet.
Step 5: Look for Cross-Links
Look for cross-links, links between different branches of the map. Novak treats cross-links as a mark of creative thinking: they show that you see how one part of the map bears on another.
Step 6: Revise as You Learn
A concept map stays open. As you read more, add concepts, re-route links, and correct the propositions that turned out to be wrong. Over time the map becomes a record of how your understanding changed.
Why Visual Concept Mapping Works
Drawing a link forces active recall: you can't connect two ideas without retrieving what you know about both. A missing or unlabeled connection is a question you haven't answered yet. Position helps too, since where things sit on the canvas becomes part of how you remember them. And the habit also carries over: once you have mapped one subject, the next one is easier to start.
Concept Mapping Software: What to Look For
You can map on paper. Software makes revision cheap, and a map you revise is a map you keep learning from. Things worth looking for:
- Connections you can label, so every link reads as a statement.
- Free spatial layout: move any card anywhere and let the structure emerge.
- Room for notes on a card, for a definition, a source, or an example.
- Export, so a finished map can go into your notes, slides, or review sheets.
- Privacy: study notes are yours and do not need to sit on someone else's server.
Concept Mapping in Redstrings
Redstrings is built around the thing concept mapping needs most: labeled relationships between cards. A string between two cards takes a label, and the label sits on the line, so the map reads as a set of propositions.
- Artifact, Process, and Event cards hold concepts, mechanisms, and the things that happen between them. Note cards are for side comments; their strings carry no label, so do not use them for concepts. Pro adds custom card types if you want one named Concept.
- Named strings capture the relationship: "grounds," "is replaced by," "leads to."
- A free canvas lets you arrange general to specific and spot cross-links.
- PNG export turns a finished map into an image for your notes or a study group.
- Local by default. Boards are files on your machine. Optional AI analysis in Pro sends the board and your Gemini key to Google.
