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,"…

In the United States, "A Framework for K-12 Science Education" (National Research Council, 2012) and Next Generation Science Standards (NGSS) offer a vision of rigorous science standards for all students across K-12 classrooms. As science and engineering practices (e.g., develop models, argue from evidence, construct explanations) are…

While there is consensus in the science education community on the importance of crosscutting concepts (CCCs) for all students, teachers have been given limited guidance on how to integrate CCCs into science instruction. In this article, the authors propose that teachers view CCCs as resources that students use in their everyday lives to make…

A "Framework for K-12 Science Education and the Next Generation Science Standards" ("NGSS") are intended for all students, hence "all standards, all students" (NGSS Lead States 2013). To make this vision a reality, the "NGSS" highlight three key instructional shifts: (1) explain phenomena or design solutions…

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") call for a high level of classroom discourse (Lee, Quinn, and Valdés 2013). To engage all students, including English learners (ELs), in this form of discourse, educators have turned to talk moves (e.g., "Say more about that"), defined as general-purpose tools for…

The adoption of "A Framework for K-12 Science Education" and the Next Generation Science Standards (NGSS) across the U.S. requires that the field of science education develops high-quality instructional materials. This need is particularly urgent as schools and districts are expected to design or adapt instructional materials for an…

While student demographics continue to change nationwide, science achievement gaps persist, as measured by the National Assessment of Educational Progress (NCES 2012). As traditional racial and ethnic minority students have become the numeric majority (NCES 2013), teaching science for all increasingly means addressing diverse student populations.…

The authors evaluated the effects of P-SELL, a science curricular and professional development intervention for fifth-grade students with a focus on English language learners (ELLs). Using a randomized controlled trial design with 33 treatment and 33 control schools across three school districts in one state, we found significant and meaningfully…

The "Next Generation Science Standards" ("NGSS") push students to have "a deeper understanding of content" (NGSS Lead States 2013, Appendix A, p. 4). However, with the reality of high-stakes assessments that rely primarily on multiple-choice questions, how can a science teacher analyze students' written responses…
