Evolving Explanations in High School Biology.
Sandoval, William A.; Reiser, Brian J.
Building explanations is fundamentally what science is about. Students require support both for constructing their own explanations about the surrounding world, and for reflecting on those explanations in ways that help them to assess the quality of their explanations and the strategies they use to build them. This paper describes the development of a high school biology curriculum which integrates technological supports for explanation construction with scaffolded classroom discussion activities to support students' reflections upon their explanations as scientific artifacts. The goals of the integrated curriculum include developing students' ideas about the nature of scientific knowledge, their skills in conducting scientific investigations, and their understanding of core theories of biology. Data collected for the study of this project consisted of the students' explanations as they worked through problems. The explanations are examined on two broad dimensions: (1) the causal coherence of their explanations; and (2) how they use data to support their explanations. Contains 16 references. (DDR)
