Concept mapping is a visual representation of knowledge that identifies relationships between concepts using nodes and links. It shows how an individual organizes their understanding of a topic. Nodes represent concepts, and labeled links show relationships. Concept mapping aids learning by integrating new and old knowledge. It helps teachers assess student understanding, identify misunderstandings, and select appropriate instructional materials. Students can use concept mapping to plan projects and develop understanding across subjects like language arts, social studies, and math.
