A technique for visualizing the relationships between different concepts. A concept map is a diagram showing the relationships between concepts. Concepts are connected with labelled arrows, in a downward-branching hierarchical structure. The relationship between concepts is articulated in linking phrases, e.g., "gives rise to", "results in", "is required by," or "contributes to". Concept mapping serves several purposes. One, which takes place via knowledge elicitation, is to represent the mental models, i.e., the cognitive map of individuals, teams and organizations. Another, which takes place by knowledge capture, is to represent the structure of knowledge gleaned from written documents. The addition of knowledge resources, e.g., diagrams, reports, other concept maps, spreadsheets, etc., to the concept nodes (attached during or after construction) has been found to significantly improve the level of meaningful learning of the concept mapper. Educators are increasingly realising the utility of such maps and have started using them in classroom.
