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…

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…

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…

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…

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…

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…

In the climate of standards-based instruction and accountability, scaling up educational innovations is necessary to bring about system-wide improvements. As a result of fundamental tensions involving effective educational policies and practices for diverse student groups, scaling up is especially challenging in multilingual, multicultural, and…
