Using a Modeling Approach To Explore Scientific Epistemology with High School Biology Students. Research Report.
This paper describes a study of high school students' participation in the construction and revision of explanatory models as they attempted to account for a variety of inheritance phenomena observed in computer-generated "fruit flies". Throughout the course students were encouraged to explore epistemological issues related to the assessment and justification of knowledge claims (explanatory models) in genetics. Findings indicate that students' conceptions of models changed during the nine-week course. Initially the majority of students equated scientific models with proof of theories but by the end of the course, most students demonstrated understanding of the conceptual nature of scientific models and the need to justify such knowledge according to both its empirical utility and its conceptual consistency.
