Tobin, Roger G.; Lacy, Sara J.; Crissman, Sally; Haddad, Nick – Journal of Research in Science Teaching, 2018
We report a case study of model-based reasoning in which a small group of fourth-grade students analyzes the energy flow when a solar panel is used to power an electric motor that spins a propeller. In developing their explanation of energy flow, the students draw on a general model of energy developed collectively by their class in the course of…

Varelas, Maria; Pieper, Lynne; Arsenault, Amy; Pappas, Christine C.; Keblawe-Shamah, Neveen – Journal of Research in Science Teaching, 2014
In this study, we examined opportunities for reasoning and meaning making that read-alouds of children's literature science information books and related hands-on explorations offered to young Latina/o students in an urban public school. Using a qualitative, interpretative framework, we analyzed classroom discourse and children's writing…
