How students restructured their scientific ideas in response to contradictions was studied with 166 male and female students (aged 12 to 14 years) who tested their predictions about water displacement by experiment. Conceptual change varied; all subjects tended to hold onto old ideas, even when presented with conflicting information. (SLD)
