The Next Generation Science Standards call for the adoption of many aspects of scientific inquiry in the classroom. The ways in which classroom talk and classroom environment change as students and teachers learn to utilize inquiry approaches are underexplored. This study examines the frequency with which linguistic markers related to access and power appear in student and teacher speech in the elementary science classroom. As teachers begin to implement argument-based inquiry methods, teacher and student use of these markers changes significantly. These changes indicate that students whose teachers utilize argument-based inquiry have greater access and power in the science classroom. In this paper, the mechanisms by which teachers afford their students access and power are explored from a quantitative perspective. C 2015 Wiley Periodicals, Inc. Sci Ed 99:238-259,

ClubProgram piloted a no-conflict approach to free, informal science activities focused on climate change or evolution, holding 64 community events at two sites over the course of 15 months, engaging with more than 70,000 participants. In the participating communities science literacy increased over time as did community engagement as measured by local financial support, requests for programming, and event attendance.
