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 study investigated how an intervention consisting of a series of physical science lessons embedded within the elementary science methods course impacted elementary preservice teachers' (N = 473) science content knowledge as evidenced in their scaled scores for the science content component of a standardized subject certification examinations…

This study aims to examine pre-service science teachers' (PSTs') model-based (MB) content knowledge (CK) and knowledge of students' understanding (KSU) of chemical bonds. The participants of the study consist of 229 senior pre service science teachers. The study is a case study from qualitative research designs. The data of the study were…

This case study explores the integration of language-generating artificial intelligence (LGAI) in K-12 instructional planning, focusing on a middle school science teacher's use of these tools within the Technological Pedagogical Content Knowledge (TPACK) framework. The study investigates two primary concerns: how LGAI is utilized for lesson…

Proton nuclear magnetic resonance ([superscript 1]H NMR) spectroscopy is an essential characterization tool for organic chemists widely taught in the undergraduate chemistry curricula. Previous work has focused on how students advance from novice to expert in interpreting [superscript 1]H NMR spectra. However, we need to know more about how…

Pedagogical content knowledge (PCK) is considered an important ingredient in shaping classroom practice. PCK requires valid measurement at domain-specific level on different components excluding the teaching context. While the research focuses on measuring the PCK of unqualified teachers and pre-service teachers, the description of qualified…

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…

The Technological, Pedagogical Content Knowledge (TPACK) model serves as a comprehensive conceptual framework that delineates the essential knowledge domains teachers must possess to effectively integrate technology within educational settings. By synthesizing technological knowledge, pedagogical knowledge, and content knowledge, TPACK empowers…

Teachers' practical knowledge is closely related to teaching practice. The purpose of this research was to develop an instrument for assessing upper-secondary school science teachers' perceived practical knowledge about practical work. The development of this instrument was based on five components in the conceptual framework of PCK about…

Reading, at its core, is a basic yet critical way to undertake learning and growth. This paper shares a professional learning and development initiative for science educators, which was underpinned by the popularity and premise of the reading group. In moving from simply being a vehicle for targeted discussion, the reading group facilitators…

The aim of the study is to adapt the "Maker-Based Technological Pedagogical Content Knowledge" scale developed by Ku et al. (2021) for pre-service science teachers into Turkish. The study group for the research consists of 188 pre-service science teachers studying at the Department of Science Education at three state universities in…

The purpose of this study is to identify the factors that shape pre-service teachers' (PSTs) online teaching practices within the technological pedagogical content knowledge (TPACK) framework. Ten science PSTs and nine mathematics PSTs who experienced the practical part face-to-face and the theoretical part online of the Teaching Practice 2 course…

Science teachers should be able to notice student preconceptions in order to adapt instructions to their students' needs and support the learning process. Noticing as a core practice of teaching should thus be implemented early in science teacher education. A crucial prerequisite for noticing is knowledge about students' preconceptions, which is…

This article reports on a study of understanding of key sub-topics of the curricular model of covalent bonding among participants at all levels of the chemical education system in Croatia, including among secondary school students, university students (some of whom are pre-service teachers), and secondary school chemistry teachers. The diagnostic…

STEM education is present in most recent curriculum reforms around the world. One of the main novelties of this educational movement is the integration of engineering practices into science education. In the Spanish educational context, this implies an important challenge for science teachers. So, this study analyzes whether secondary science…
