Examined the problem-solving performances of novices (11 undergraduates) and experts (9 graduate students and instructors), comparing them in terms of background expertise and problem-solving success. Also examined problem-solving behaviors reported in other domains and determined whether or not genetics is a fruitful area for problem-solving…

This paper is a progress report of the first phase of a project which essentially seeks to replicate previous studies using the successful/unsuccessful design in an attempt to: (1) corroborate the surface/deep structure conclusion which has become an essential component of an understanding of problem-solving; (2) examine more closely the nature of…

Nine undergraduate science and non-science majors (novices) who had recently completed their first college classroom study of genetics and seven genetics graduate students and biology instructors (experts) were videotaped as they attempted to solve a selected group of seven moderately complex classifical genetics problems and three Piagetian tasks…

The mental representations used by experts and novices for organizing their knowledge of a discipline have been studied by observing the categorization schemes these subjects produce when presented with a diverse group of problems. In this study, seven biology faculty, eight certified genetic counselors, and 26 students were asked to organize a…

Compares 7 biology faculty members, 9 genetic counselors, and 26 undergraduate students according to both expertise and problem-solving success within the domain of genetics. Findings are consistent with the hypothesis that as expertise is attained, the individual restructures knowledge into a framework based upon the critical dimensions which…
