The Development of Expertise in Science Investigation Skills.

This paper reports on a study that compares the performance of school students, university students and expert research scientists on a practical, laboratory-based, science investigation task. Data reveal limitations in the work of the school students and provide insights into the development and nature of expertise in science investigation skills. Recommendations are made for modification of school and university laboratory work to more effectively develop expertise in those investigation skills given high priority in the National Science Statement and the Mayer report.
