Stamovlasis, Dimitrios; Tsitsipis, Georgios; Papageorgiou, George – Chemistry Education Research and Practice, 2010
This work uses the concepts and tools of complexity theory to examine the effect of logical thinking and two cognitive styles, such as, the degree of field dependence/independence and the convergent/divergent thinking on students' understanding of the structure of matter. Students were categorized according to the model they adopted for the…
