Concept Maps
 Concept maps are tools for organizing and representing knowledge1
 Concept maps include “concepts” which are connected by lines to form “propositions”. The
lines are labeled to specify the relationship between the concepts.
 They are typically represented in a hierarchical fashion, with more general concepts at the
top / center, and more specific, less general ones at the the bottom or extremities.
 The hierarchy depends on some context in which the knowledge is applied, such as with
respect to a specific question.
 Cross links may connect concepts that are at different geographical locations of the map.
Such links represent the multidisciplinary nature of the topic and the creative thinking
ability of the person preparing the map.
 Creating concept maps is not very easy, and requires some amount of familiarity with the
technique as well as the context. No concept map is ever final, as it can be continually
improved. One should be careful however, against frivilously creating concepts and/or links
between them (which result in invalid propositions).
 Concept maps provide a very powerful mechanism for presenting the relationships between
concepts as well as the preparer level of understanding of these concepts.
