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,"…

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…

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…

In this paper, we critically examine the way in which scholars have traditionally defined and problematized attrition. Through a series of examples of large-scale intervention impact studies, we share insights about the sources and consequences of attrition that expand our notion of how and why attrition occurs. We also discuss potential steps 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…

The latest content standards in U.S. K-12 education are academically rigorous for all students, including a fast-growing population of English learners (ELs). Because these standards are different from previous standards in terms of not only their rigor but also their theoretical underpinnings, enacting instruction aligned to the standards will…

Engineering has led the way in responding to the COVID-19 pandemic, including developing masks that reduce transmission, digital tools that allow contact tracing, and vaccines that show promise to put an end to the pandemic and allow a more normal way of life. Society is not only "following the science," but is also applying principles…

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…

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…

Research on TESOL materials development has focused primarily on instructional materials for contexts in which students are learning English separate from academic content (e.g., science, mathematics). This research could benefit from expansion given the increasing number of contexts in which students are learning content and English language…

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…

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…

According to the vision of the "Next Generation Science Standards" (NGSS), science and engineering are language intensive and offer both opportunities and challenges for all students, especially English learners (ELs), who are developing language and disciplinary knowledge and practices simultaneously. To support ELs of varying levels of…

Teacher knowledge of science content is an important but under-studied construct. A curricular and professional development intervention consisting of a fifth grade science curriculum, teacher workshops, and school site support was studied to determine its effect on teachers' science content knowledge as measured by a science knowledge test,…

As the Common Core State Standards (CCSS) for English language arts (ELA)/literacy and the Next Generation Science Standards (NGSS) highlight connections across subject areas, convergences and discrepancies come into view. As a prominent example, this article focuses on how the CCSS and the NGSS treat "argument," especially in Grades…
