What an Open Source Concept Map Shows
An open source concept map is a diagram of ideas and the links between them, shared under a license that lets anyone view, copy and adapt it. Concept maps usually place a central topic at the top and connect it to key concepts through labelled relationships. Good examples show how core ideas branch into supporting details, which makes them useful for study, teaching and planning.
- Central topic: the main question or subject the map is built around
- Key concepts: the main ideas that sit on the first branches
- Linking phrases: short labels that explain how two concepts relate
- Supporting examples: specific facts or cases attached to each concept
Use the map to review relationships before an exam, or to plan a project step by step. CogniGuide can build a personalized concept map from your own notes, so you can adapt the structure to your course.
