Differences in Knowledge Networks about Acids and Bases of Year-12, Undergraduate and Postgraduate Chemistry Students.
Wilson, Janice M.
Research in Science Education, v28 n4 p429-46 1998
Differences in the status of ontological categories on the concept maps of secondary-, undergraduate- and graduate-level chemistry students were analyzed with the "Pathfinder" scaling algorithm and multidimensional scaling. Results indicate differences among groups in the structural significance of abstract process-related nodes and matter-related nodes on the topic of acid-base equilibria. Discusses implications for theories of conceptual change. Contains 48 references. (Author/WRM)
