Perspectives on concept mapping and its benefits to students in the learning of scientific concepts are presented in this paper. A concept map is defined as a two-dimensional heirarchical representation of concepts which indicates the relationship between the selected concepts. Aspects of concept mapping addressed in this review include: (1) its structure (consisting of a sample map); (2) construction of a map (specifying the steps involved in mapping); (3) applications (indicating uses in curriculum development, instruction, and evaluation); (4) classroom use (suggesting ways for introducing concept mapping to students); (5) research studies (reviewing one study's findings); and (6) a conclusion (re-emphasizing the instructional value of concept mapping).
