Samarapungavan, Ala; Bryan, Lynn; Wills, Jamison – Journal of Research in Science Teaching, 2017
In this paper, we present a study of second graders' learning about the nature of matter in the context of content-rich, model-based inquiry instruction. The goal of instruction was to help students learn to use simple particle models to explain states of matter and phase changes. We examined changes in students' ideas about matter, the coherence…

Grotzer, Tina A.; Solis, S. Lynneth – Journal of Research in Science Teaching, 2015
Spatial discontinuity between causes and effects is a feature of many scientific concepts, particularly those in the environmental and ecological sciences. Causes can be spatially separated from their effects by great distances. Action at a distance, the idea that causes and effects can be separated in physical space, is a well-studied concept in…

Varelas, Maria; Pappas, Christine C.; Tucker-Raymond, Eli; Kane, Justine; Hankes, Jennifer; Ortiz, Ibett; Keblawe-Shamah, Neveen – Journal of Research in Science Teaching, 2010
In this study we explored how dramatic enactments of scientific phenomena and concepts mediate children's learning of scientific meanings along material, social, and representational dimensions. These drama activities were part of two integrated science-literacy units, "Matter" and "Forest," which we developed and implemented…
