"Concept-mapping–or mind-mapping, idea-mapping, or some other variation that makes sense to you–is the practice of demonstrating the relationship between ideas in a map-like form.
Concept-mapping allows creators to articulate nuance, context, and interdependence between ideas in a very user-centered way. This makes them especially useful in education, whether you use them for pre-writing, research notes, or “back-mapping” a unit or unit assessment. They encourage macro-thinking, can provide a bridge to struggling writers who have trouble turning their thinking into prose, and are a powerful tool for visual learning."
