Abstract
Goldsmith et al.’s closeness measure, developed for evaluating structural representation of knowledge, has been applied to assess concept maps and the effectiveness has been positively affirmed. The measure quantifies the configural similarity between two networks by examining the degree to which the same node in two graphs is surrounded by a similar neighborhood of nodes. Once it is applied to concept map scoring, it would neglect the meaning relationship between concepts. Considering a proposition is the basic unit of meaning in a concept map, this study proposed that a concept map be transformed into a proposition-based map before applying the closeness measure. To validate the approach, 197 students’ concept maps were collected and scored. The scores derived by the closeness measure on the original concept maps and the transformed proposition based maps were compared with the scores by Novak and Gowin’s scoring scheme (criterion). The statistical analyses showed that the correlation between the scores from proposition based closeness measure and the criterion scores (r = .888, p < .01) was significantly higher than that between concept based closeness measure and the criterion scores (r = .712, p < .01).
