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…

This design-based research project reports on three multilevel networks that were focused on implementing the Next Generation Science Standards (NGSS). Given the recent attention to understanding infrastructure to craft coherence in NGSS implementation, this research investigated how these networks iteratively re-designed infrastructure as they…

The COVID-19 pandemic is a historic global event that has extended to all parts of society and shaken the core of what we know and how we live. During this pandemic, the work of STEM professionals has taken center stage. Through our close observations of how the events of the pandemic have been unfolding across the globe, we propose an…

This article addresses two gaps in the literature related to science department chairs: the axiological relationship between the chair and science, the subject, and the perceptions of the chair with respect to teaching and learning within their departments. In this work, axiology is used to understand how the chair's values toward the subject…

Background: It is crucial to support students in better understanding water and sustainability issues because water plays a vital role in maintaining global ecosystems, including human life. A wide range of curricular and instructional supports like those embodied in model-based learning (MBL) are necessary for teachers to engage students in the…

Understanding factors that influence teacher use of professional development learning is critical if we are to maximise the educational and financial investment in teacher development. This study used a multi-case mixed methodology to investigate the factors that influence teacher adoption, adaption, and abandonment of teacher-directed learning.…

This research explores how explaining an anchoring phenomena and engaging students in investigations, as central designs of a model-based inquiry (MBI) unit, afforded or constrained the representation of scientific activity in the science classroom. This research is considered timely as recent standards documents and scholars in the field have…

Cultivating students' scientific knowledge and developing their capability in scientific inquiry depends on a teacher's ability to use existing resources to design rich learning opportunities. Designing such experiences is not easy, and is particularly challenging for new teachers who have little experience making decisions about the best way to…

Comprehensive reviews of empirical research on teacher leadership have revealed that this body of research remains grounded in what might be described as, at best, a weak theoretical base. This article seeks to address this by proposing a theoretical framework based on social learning theory, communities of practice, and identity and iterated…

While the literature is replete with studies examining teacher knowledge and pedagogical content knowledge (PCK), few studies have investigated how science teacher orientations (STOs) shape classroom instruction. Therefore, this research explores the interplay between a STOs and the topic specificity of PCK across two science topics within a grade…

In the United States and internationally, there has been an increased emphasis on the practice turn or a focus on engaging students in more authentic representations of how science is practiced. In this article, we describe the development of a student questionnaire to investigate the extent to which students report being engaged in learning…

Science students should use mathematical and computational thinking to explain phenomena, but few examples of teachers engaging students in this important scientific practice have been found. This article describes a strategy for enhancing a lesson in which students use a mechanistic model to explain friction by adding mathematical and…

In this article, we examine how the concept of autonomy may be construed as a foundational value which underpins students' coherent sensemaking of how the physical world operates. Autonomy and science both require students to comprehend and assess the quality of evidence, claims, and alternative outcomes. Further, participation in scientific…

Purpose: Drawing upon research into standards reform, and theorizing of professional and political capital, this article seeks to understand the development of and advocacy for the Next Generation Science Standards in the United States. As well as revealing how professional capital exists in three dimensions--human, social, and decisional--the…

The vision of Next Generation Science Standards (NGSS) "requires a dramatic departure from approaches to teaching and learning science occurring today in most science classrooms K-12" (Reiser 2013, p. 2). In this article the authors emphasize the importance of examining student misconceptions and correcting them with sense-making…
