Abstract
Although educational research and practice has found many benefits of long-term and complex design activities, an issue of growing concern is that students might lose sight of science learning while diverting their attention to design aesthetics, collabo- rative management, and technology. A question is whether or not science is actually separate from these aspects; it may be that science permeates the design environment and is thus contexted within these other activities. To investigate this possibility we followed a classroom of 33 students, divided into 7 teams, and we examined their sci- ence discussions as they planned for creating instructional software designs. Spe - cifically, we investigated which conversational contexts gave rise to science talk. We found that a focus on the fine-grained details of the instructional science designs themselves and the contributions of more design-experienced students played an im- portant role in the sophistication of the science content in the planning discussions. In examining less productive contexts for science talk, we found that a conversational focus in planning discussions on collaboration and software issues, as well as the sci - ence focus of the software designs, impacted the quality of science integration. In our discussion, we address the issue of which design contexts afford opportunities for richer discourse and the implications for other project-based design activities.
