Effects of an Environmental Education-Related STS Approach Instruction on Cognitive Structures of Preservice Science Teachers.
McClure, John R.; Bell, Paul E.
Concept maps provided a measure of subjects' cognitive structures before and after completion of an environmental education course. Concept maps were constructed from expressions taken from the issue "global climate." Expressions were assigned to one of three domains: science, technology or society. Maps were analyzed by constituent propositions, which were categorized by various characteristics including the domains of the expressions connected, the relationship expressed and the strength, determined by a protocol developed for this study. Significant differences were found in the frequencies of occurrence for various proposition characteristics and these were correlated with previous academic experiences. Some proposition characteristics were also correlated with the results of a final examination. Comparison of concept maps prepared before and after an environmental education course showed some changes in proposition characteristics. A brief description of the course, the expressions used in the concept mapping activity, a description of "networking" symbols and a sample map, the protocol used to evaluate the concept maps, and the results of the statistical analysis are appended.
