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…

This mixed-methods study examines how pre-service teachers select instructional videos on YouTube for physics teaching. The study focuses on the role of surface features that YouTube provides (e.g., likes, views, thumbnails) and the comments underneath the videos in the decision-making process using videos on quantum physics topics as an example.…

This study aimed to examine the integration of four elementary science teachers' technological pedagogical content knowledge (TPACK) components during emergency remote teaching. Data sources included teaching video recordings and stimulated interviews conducted after analyzing the teachers' teaching videos. The data were analyzed by identifying…

The development of scientific reasoning competencies is a key goal of science education. To better understand the complex construct of scientific reasoning, which includes modeling as one style of reasoning, thorough investigations of the underlying processes are needed. Therefore, in this study, a typology of preservice science teachers' modeling…

This article provides rich insights into the process of data generation for discourse analysis from three separate studies of the video recordings of a single science classroom in action. The central claim is that multimodal transcription can contribute to developments in discourse theory. A three-stage reflective heuristic is developed and used…

Despite the fact that the majority of museum visitors are often very young children, much research in museums focuses on pre-teen learners (ages 8-12). Our goal in this study was to investigate the behaviors of children aged 5-8 during a visit to a science exhibition. We aim to develop a methodology to assess children's levels of engagement with…

Teachers' development can be seen as a dialog between their reflective thinking and their actions, with an added gradient of complexity from their social interactions. All of these elements are conjugated within their classroom practice, with their Pedagogical Content Knowledge (PCK) as theoretical background. This paper analyzes the case of a…

The meaning-making practices of science are multimodal and include representational forms such as spoken and written language, diagrams, graphs, equations, and images. Science learning proceeds through an ever-increasing grasp of such resources. This study aims at providing insight into how a combination of Interaction Analysis (IA) and social…

This study investigated science classroom discourse in terms of the types of teacher discursive moves (TDMs) and the relationships between the types of TDMs and student-led cognitive contributions in different science concepts by considering the classroom context. An experienced seventh-grade science teacher and her 19 students were engaged in…
