The Effects of Definition and Instance Presentation on Concept Acquisition.
Osguthorpe, Russell T.; And Others
A 4 x 4 factorial experiment was conducted with 152 college age volunteers to investigate the effects of different forms of mathemagenic information (algorithms, heuristics, attribute elaboration, and attribute isolation) on concept acquisition. Results showed that both definition and instance presentation had a significant effect on students' ability to correctly classify novel instances and their confidence in their responses. It was shown that heuristic definitions produce patterns of confidence that differ from those of other definition types. It can be concluded that: (1) definition and instance presentation both play an important role in concept acquisition, (2) students can benefit both affectively and instructionally from the expository presentation of classification algorithms and heuristics and (3) confidence is more closely related to definition than to inquisitory instance presentation.
