Computational models are increasingly being used in K-12 science classrooms to engage students in developing and testing explanations of phenomena. However, research has only begun to consider whether integrating computational models into science instruction could be particularly beneficial to students from diverse backgrounds, including a…

The Next Generation Science Standards (NGSS) have spurred renewed interest in the epistemologies that students adopt as they engage in science practices. One framework for characterizing students' epistemologies is the "epistemologies in practice" framework (Berland et al. (2016), "Journal of Research in Science Teaching,"…

As computational models are becoming more widely used with the release of "A Framework for K-12 Science Education" (NRC 2012) and the "Next Generation Science Standards" ("NGSS"; NGSS Lead States 2013), these models are reshaping the way science is practiced in increasingly diverse classrooms. For students classified…

The "Next Generation Science Standards" ("NGSS") shift what it means to teach and learn science. One significant change emerges from the central role of discourse. As the practices are language-intensive and the performance expectations explain what a student should be able to do in science, every student must learn the…

Background: Current classroom practices have largely been shaped by changing student demographics, including English language learners (ELLs), and evolving accountability policies. The teacher professional development intervention in this study takes place against this backdrop. Research Questions: This study examined change in teachers' knowledge…

This article is situated within a theoretical framework, "instructional congruence," articulating issues of student diversity with the demands of academic disciplines. In the context of a large-scale study targeting elementary school science, the article describes a research instrument that aims to combine the strengths of both quantitative and…
