|Abstract:||We present two case studies of scientific inquiry with Embedded Phenomena, where two middle school science classes participate in whole-class investigations of phenomena that are embedded within their classroom. Students share observational data with their peers using networked handheld devices. Student-contributed data is collected, aggregated and re/presented in coherent visualizations, designed to guide students in their investigations. We examine the forms of these collective representations with a view towards understanding their efficacy in scaffolding learners and resolving their driving inquiry questions. We analyze the patterns of discourse and of use surrounding these aggregate visualizations during teacher-led, whole class discussions. For each case, we report three trends based on a visual analysis of the coded discourse, followed by a discussion of the patterns of use surrounding the display of aggregate screens. We conclude with a synthesizing discussion of the two cases.|
