Recent national reforms focus on learning disciplinary core ideas through engaging in science and engineering practices. These reforms also call for students and teachers to use crosscutting concepts (CCCs), or analytical lenses, that support scientific sensemaking and connections across disciplines. The "Framework for K-12 Science…

Virtual reality (VR) in science classrooms has the potential to enhance students' learning by bridging the knowledge in the learners' communities with science instruction. When virtual environments reflect students' culture, it has the potential to influence their attitudes toward the value of science in their community. This qualitative study…

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…

Project-based learning (PBL) is a long-standing curricular model that has been argued to support equity-based goals in science learning. Yet, little is known about how PBL can be implemented effectively and equitably in the context of virtual instruction. This comparative case study follows two elementary science teachers as they transition to…

There is growing recognition of the prevalence of "within school churn", a phenomenon in which teachers remain within a school but are assigned a new grade level or course. In this study we examine the consequences of within-school churn for the pedagogical content knowledge of elementary teacher participants in an NSF-funded science PD…

With the growing adoption of the Next Generation Science Standards across the United States, elementary teachers are being called upon to incorporate engineering into their science instruction, creating a need for ways to help elementary teachers better understand what engineering is and how to accurately communicate it to students. The present…

Engineering design activities are a common way for teachers to incorporate engineering into their science classrooms, as called for by current science policy documents in the United States. However, little is known about how teachers prioritize different learning objectives during engineering design lessons. Understanding teachers' thinking on…

The Next Generation Science Standards call for changes in not only what is taught in elementary science but also how students engage in the learning experience to develop understanding of core disciplinary ideas. In this study we examined 5th-grade teachers' pedagogical content knowledge (PCK) for 1 particular core idea: the small particle model…

Elementary school teachers' perceptions of school resources (i.e., material, human, and social) for teaching science to diverse student groups were examined across three school districts from one state. As part of a 3-year curricular and professional development intervention, we examined the effect on teachers' perceptions after their first year…

This study explored the nature of the relationship between a fifth-grade teacher and an informal science educator as they planned and implemented a life science unit in the classroom, and sought to define this relationship in order to gain insight into the roles of each educator. In addition, student learning as a result of instruction was…

Anecdotal accounts from science educators suggest that few teachers are teaching science as inquiry. However, there is little empirical evidence to support this claim. This study aimed to provide evidence-based documentation of the state-of-use of inquiry-based instruction and explicit instruction about nature of science (NOS). We examined the…
