This study focuses on how science teachers' Pedagogical content knowledge (PCK) can be captured and developed with the support of Content representation (CoRe) in combination with video-based reflection when they plan, teach, and reflect on their teaching in sustainable development (SD). The theoretical framework is based on PCK, and the Refined…

Background: Effective science teaching requires a specialised body of knowledge. Researchers have recognised the importance of understanding the incoming knowledge that pre-service science teachers (PSTs) bring to their initial teacher education. However, although many studies have focused on PSTs' declarative knowledge or the knowledge that…

Taking the "practice turn" in K-12 science classrooms requires students to engage in processes of knowledge building, constructing explanatory accounts of natural phenomena. To support students in these sensemaking opportunities, a significant departure is needed from how science is typically taught in many classrooms. Teachers will need…

The specific focus of this study is how a team of four preservice teachers experienced a collaborative practicum model to support the development of cogenerative dialogue and foster professional growth. Data sources included individual video club annotations and the associated group discussions facilitated by comparison of groups members selected…

High school chemistry teachers are increasingly expected to teach materials science content, often without formal preparation in the field. This study examines how 20 experienced chemistry teachers engaged with solid-state topics within a graduate-level chemistry course designed to support dual-enrollment instruction. Using a social annotation…

Teaching science to elementary school students is complex, and teacher preparation programs must support pre-service teachers' learning to communicate science content and practices with children. Science teachers bring the experiences they have as students to their teacher preparation, and these experiences may support or conflict with what they…

Background: Science teaching and learning, as discursive practices, occur through the utilization of various semiotic modes. Gestures play a pivotal role as an embodied mode that acts in conjunction with speech in oral communication settings, such as classrooms. Previous research on gestures in chemistry and science education has illuminated how…

Knowing how science teachers develop their professional knowledge has been a challenge. One potential way to determine the professional knowledge of teachers is through videos. In the study described here, the authors recruited 60 elementary and secondary science teachers, showed them one of two 10-min videos, and recorded and analyzed their…

This research will analyze the issues encountered by two science teachers implementing Arduino-based robotic coding projects. This research employed a case study design. This research has used a criterion sampling group. This study used semi-structured observation, interviews, and video observations as data collection tools. The teachers conducted…

Sensemaking has been advocated as a core practice of science education to support students in constructing their own understanding through a prolonged trajectory. However, the field lacks a discussion of teaching strategies that can better support students as they develop in the trajectory of sensemaking, which includes four phases: initial…

Science teachers have been urged to use emerging technologies, such as robots, in ways that empower K-12 students as active participants responsible for their learning and knowledge development within the scientific domain. And yet, little is known about whether the use of robots effectively supports students' epistemic agency in science learning.…

We present an empirically based model for modeling the quality of pre-service teacher reflection. Conversations from twelve groups of a total of 47 pre-service teachers were video recorded and transcribed verbatim. First, we analyzed their conversations through practical epistemology analysis and an operationalization of Dewey's definition of…

Our study examines the scaffolding strategies employed by secondary biology teachers to support multilingual learners (MLs) in engaging with Science and Engineering Practices (SEPs). Rooted in sociocultural theory, we focus on the integration of academic language in disciplinary practices. Data from video-recorded observations of 12 secondary…

Background: Dialogue between the teaching profession and researchers regarding pedagogical strategy is sometimes problematic. Pedagogy research may benefit from incorporating research methods that can investigate teachers' and pupils' interpretations. Purpose: This research expands the Pedagogy Analysis Framework (Riordan, 2020) by explaining in…

Literature suggests the transfer of understanding the nature of science to instructional practice requires preservice teachers to value teaching about the nature of science. Despite decades of research developing preservice teachers' views of nature of science, there is still a disconnect between their understanding and instructional practice.…
