Although teachers have opportunities to learn about many things through teaching experience, we know little about how they develop science subject matter knowledge in this setting. With both limited opportunities to learn science subject matter knowledge before becoming teachers and minimal science professional development available while working…

To gain a holistic understanding of how science teachers dealt with STEM education, this study explored two science teachers' perceptions and practices at primary schools via the lens of curriculum ideology. By examining their perceptions and practices from six essential aspects (i.e., aim, content, student, teaching, learning, and assessment), we…

Students often learn about measurement uncertainty as an isolated topic, with a focus on generalizable strategies to manage uncertainty in scientific investigation. In this study, we report and analyze a case of emergent learning about measurement and uncertainty, in which students in a Chinese elementary school science class explored and…

As linguistic diversity continues to increase in the United States public school system, schools are expected to meet the needs of their ever-changing student body. While much attention within education research has understandably focused on multilingual learners' (MLs) English language acquisition, an emergent body of work points to science as an…

This study reports on a case study about multimodal work in a primary physics classroom focusing on forces. Previous research reports that students benefit from multimodal work in science classrooms. Yet, few systematic studies have been performed to reveal how students represent their experiences and ideas of science phenomena over time within…

In this study, we investigated the construction of science learning opportunities focusing on space-time relationships. Guided by ethnography in education, we followed the everyday life of a classroom over their three first years at elementary school. Based on macroanalysis, we examined discursive interactions in temporally distant events and how…

This paper is part of the special issue on Teacher Learning and Practice within Organizational Contexts. Shifting instructional practices in elementary schools to include more equitable, reform-based pedagogies is imperative for supporting students' development as science learners. Teachers need high quality professional development (PD) to learn…

Science teachers struggle to implement and sustain new curricular ideas from professional development (PD) experiences. These PD opportunities are crucial for enacting real-world changes to teaching practice and address pressing global challenges, such as the teaching and learning of socioscientific topics nested in school communities.…

As a hallmark of authentic science practices, students need to enact epistemic agency to shape/reshape the key aspects of their inquiry work as a collaborative community. This study elaborates an emergent temporal mechanism for engaging students' epistemic agency: "reflective structuration" by which members of a classroom community…

In science education, there has been a sustained focus on supporting the emergence of science practices in K-12 and field-based settings. Recent work has elevated the integral role of emotion in sparking and sustaining such disciplinary practices, deepening the field's understanding of what is entailed in "doing" science. Yet even as we…

Although visual aids are widely considered a valuable source of scaffolding, the nature and active utilization of these aids in current science classrooms are not well understood. This qualitative study explores interaction in the teaching of concepts related to evolution, with a specific focus on a teacher's use of different visual support…

How anthropomorphic reasoning functions in scientific thinking has been a controversial topic. There is evidence it is problematic as well as evidence it can play productive roles, for scientists and for students. In science education, however, the prevailing view remains that it is an impediment. For this study, we have chosen examples of what we…

This study aimed to explore what kinds of epistemological messages were conveyed through teacher discourse in modeling-based and traditional elementary science classrooms and how teachers framed the two classrooms distinctively through these messages. Data came from two sixth-grade teachers' science classrooms--one characterized as a…

Critiquing arguments is important for K-12 science students to learn but not emphasized by the predominant claim-evidence-reasoning (CER) argumentation model. Drawing on the work of Yu and Zenker (2020), and Dove and Nussbaum (2018), we developed a tool for supplementing CER with critical questions (CQs) from philosophy that cover most, if not…

Elementary teachers are tasked with the challenge of implementing Next Generation Science Standards-aligned projects that integrate science, technology, engineering, mathematics, and computer science (STEM + CS) in a variety of classroom contexts. This study investigates how teachers verbally support students in two classrooms, one general…
