How the concept map approach works

The concept map approach asks you to place key concepts in nodes and connect them with short labeled phrases, so each link reads as a statement like causes or is part of. Developed by Joseph Novak at Cornell in the 1970s, it shows structure that a plain list of terms hides.

  • Start with five to ten core concepts before adding detail.
  • Keep each node to a few words and each linking phrase short.
  • Add at least a few cross-links between branches.
  • Treat the first map as a draft and revise it after each study session.
Example concept map approach components
Core parts of a concept mapConcept nodes · Linking phrases · Hierarchy from general to specific · Cross-links between branches
Linking phrasesShort verbs or prepositions · Examples include causes, requires, is part of · Turns two nodes into a testable statement
Hierarchy in a concept mapMost general concept at the top · Specific examples below · Shows the structure of a topic at a glance
Cross-linksConnect ideas across branches · Show relationships a list would hide · Often where new understanding appears
Common concept mapping mistakesToo many words per node · Missing linking phrases · Treating the first draft as the final answer

Labeled connections

Every link between two ideas gets a short phrase, so the map states relationships instead of just grouping topics.

Editable branches

Move nodes, rename concepts, and add cross-links yourself. The first draft is a starting point, not a final answer.

Explore at your own pace

Expand and collapse branches to focus on one section of a chapter, then zoom out to see how the whole topic fits together.

How it works

Upload your material

Add a PDF, DOCX, PPTX, plain text notes, or a photo of a page. Images are read with text recognition.

Review the draft map

Check the main concepts and linking phrases against your source, then rename or reorganize anything that does not match.

Study the connections

Explore each branch, quiz yourself on the relationships, and export when you are on a paid plan.

Most good maps put the broadest idea at the top and move toward specific examples below. Cross-links between distant branches are often where the real understanding shows up, because they reveal how one topic depends on another.

DeckOwl applies the same logic to your own notes: it proposes concepts and relationships, and you refine them until the map matches what your course actually teaches.

Frequently asked questions

How many concepts should a concept map have?

There is no fixed number, but starting with five to ten core concepts keeps the map readable. Add detail only where your notes show a clear relationship.

What makes a link in a concept map useful?

A useful link uses a specific linking phrase, such as requires or leads to, that makes the relationship testable. Vague links like related to are hard to check later.

Can I export my mind map?

Exporting is a paid feature. The free plan lets you study in the browser, while Plus includes PDF, DOCX, Anki, and CSV export.

Is there a free way to try it?

Yes. The free plan includes 3 generations per month, and you do not need a credit card to start.
