What is a concept map? Make the arrows say something

Three small handwritten cards connect a plant with its roots and leaves — AI-generated photorealistic illustration created for BrainiLab; an imagined editorial scene.

The links carry the meaning

A concept map shows concepts and the relationships between them. Words on the connecting lines explain how the ideas fit together.

Joseph Novak and Alberto Cañas describe this structure in their IHMC guide. The arrows are doing more than decorating the page.

Three boxes are enough

Try the question “What does a plant need?” Put plant in one box, light in another and water in a third. Label each connecting line “needs”.

Now you can read two statements: a plant needs light; a plant needs water. An unlabelled line would leave the relationship for someone else to guess.

Find the awkward link

Start with a question rather than every fact you can remember. The IHMC guide calls it a focus question. Add detail when it helps answer that question.

If a connection is difficult to label, pause and ask what you mean. That small hesitation can be more useful than another colour. For a different way to organise information, explore chunking.
