Concept Maps  Concept maps are tools for organizing and representing knowledge 1  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. 1.
