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…

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…
