Background: In the context of recent research in science education and continued struggles to understand how best to support science teachers, epistemological frames, made up of sets of epistemological resources teachers activate, have emerged as an important focus of research. However, at the time of this writing no research was available to…

Understanding the nature of science (NOS) has emerged as a core curricular goal since at least the 1960s. While science education reforms around the world have shed light on various epistemic and social underpinnings of science, how science curriculum documents portray the nature of other related disciplines such as mathematics and engineering has…

With school populations across the country becoming increasingly representative of students from diverse cultural and linguistic backgrounds, new considerations must be made to promote equitable and engaged science learning for all students (National Academy of Science, National Academy of Engineering, & Institute of Medicine [NAEEM], 2011).…

The Next Generation Science Standards (NGSS) emphasize engaging students in science practices through which students can develop content, procedural, and epistemic knowledge of science. To accomplish this goal, science teachers must embed science content in authentic science practice. Successfully integrating content and practice will require…

We report on one teachers' efforts to re-design an entire instructional unit as a coherent storyline about forces and motion as a part of a multiyear professional development (PD) project around the NGSS. Designing coherent storylines demands that teachers create opportunities for students to meaningfully engage in science practices in order to…
