Reforms such as the Next Generation Science Standards (NGSS) call for substantial change in teacher practice such as instruction that is more phenomenon-based, three-dimensional, supportive of student epistemic agency, and coherent from the student perspective. Such change requires ongoing support in the form of aligned curricular materials and…

The adoption of the Next Generation Science Standards (NGSS) requires many teachers to drastically change their classroom instruction. Curricular materials offer a tool to support this transition, but there are questions about the degree to which available curricula truly reflect the shifts required by the NGSS. This study proposes a framework of…

Recent reforms in science education advocate for a vision of learning where students "figure out" science ideas through engagement in science practices. Consequently, there have been significant efforts to engage K-12 students in the science practices. However, less research attention has been given to understand how this…

Background: Teachers need to make sense of curricular materials and design instruction to ensure students will be positioned to pursue their own arc of inquiry in curriculum enactment. Whole-group discussions are crucial opportunities for curricular sensemaking, yet planning and enactment can be challenging. Methods: We used a single, revelatory…

We present lessons learned from an ongoing attempt to conceptualize, develop, and refine a way for teachers to gather formative assessment evidence about classroom argumentation as it happens. The system--named DiALoG (Diagnosing Argumentation Levels of Groups)--includes a digital scoring tool that allows teachers to assess oral classroom…

A key goal of recent reforms in science education has been to support students' collective sensemaking, in which they work together to understand a natural phenomenon. This work is often done during class discussions, but facilitating those discussions is challenging. In this study, we used a framework of three discussion types to investigate how…

Teacher attrition rates are high in urban schools, particularly for new science teachers. Little research has addressed how science teachers can be prepared to effectively bridge the divide between preparation and urban teaching. We utilized the theoretical frameworks of social justice, identity, and structure-agency to investigate this…

Purpose: In U.S. public schools, principals must implement reforms that require instructional leadership across subjects, though little is known about subject-specific supervision. Methods: Through interviews with 26 K-8 principals, we examine instructional leadership for science. Findings: Our findings showed that science supervision occurred…

Research and reform efforts frequently identify evidence as an essential component of science classroom instruction to actively engage students in science practices. Despite this agreement on the primacy of evidence, there is a lack of consensus around what counts as "evidence" in k-12 classrooms (e.g., ages 5-18): scholarship and…

Recent reform efforts in science education include a focus on science practices. Teachers require support in integrating these practices into instruction. Multimedia educative curriculum materials (MECMs), digital materials explicitly designed to support teacher learning, offer one potential resource for this critical need. Consequently, the…

School principals play a key role as instructional leaders in reform efforts, yet little is known about their knowledge of science. A key focus in recent reform efforts is the inclusion of science practices, which are potentially a significant challenge for schools. Consequently, we investigated K-8 principals' views of good science instruction…

Fidelity of implementation (FOI) has received attention in calls for funding and research; however, there are numerous ways of conceptualising and measuring this construct. We argue that this conceptualisation is important for recent reform efforts focused on science practices. Consequently, we explored FOI in the context of the enactment of a…

Argumentation, a key epistemic practice in science, engages students in socially constructing knowledge claims using evidence. However, teachers need support in integrating argumentation into classroom instruction. We examined teachers' enactments of an educative science curriculum and their curricular decision making for argumentation. Ten middle…

The implementation of science reform must be viewed as a systems-level problem and not just focus on resources for teachers and students. High-capacity instructional leadership is essential for supporting classroom science instruction. Recent reform efforts include a shift from learning about science facts to figuring out scientific phenomena in…

Educative curriculum materials provide teachers with authentic opportunities to learn new skills and practices. Yet, research shows teachers use curriculum in different ways for different reasons, and these modifications could undermine the learning goals of the curriculum. Little research, however, has examined the variation in teacher use of…
