Expertise and the Organization of Knowledge: Unexpected Differences among Genetic Counselors, Faculty, and Students on Problem Categorization Tasks.
Peer reviewed Peer reviewed
Smith, Mike U. – Journal of Research in Science Teaching, 1992
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…

A Comparison of the Classroom Dynamics of a Problem-Solving and Traditional Laboratory Model of Instruction Using Path Analysis.
Peer reviewed Peer reviewed
Pizzini, Edward L.; Shepardson, Daniel P. – Journal of Research in Science Teaching, 1992
Compares models of the classroom dynamics for a traditional laboratory setting and a problem-solving-centered environment, both at the eighth grade science level. Descriptive data indicate no differences in the models, whereas path analyses suggest that, in the problem-solving model, student behaviors significantly correlate to lesson structure,…
