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…

Previous investigations into first year calculus students' understandings of tangent lines have revealed common misconceptions arising either from students' prior experiences with the topic or from the treatment of the subject in the calculus classroom. This study seeks to examine in-service secondary mathematics teachers' conceptions of tangent…

Teachers' reflections on their practice are a powerful tool for measuring and supporting their professional knowledge. Pedagogical content knowledge is one of the most influential domains of teacher professional knowledge. This multiple-case study investigated the topic-specific pedagogical content knowledge (TSPCK) components that Zambian…

Educating students to apply probability literacy and reasoning in out-of-school contexts requires the previous preparation of teachers, which should include the assessment of their mathematical and didactic knowledge. Consequently, we investigated three research questions concerning the probabilistic reasoning and literacy of 66 prospective…

Internal and external factors influence teachers' daily assessment decisions. The purposes of teachers' assessments are crucial, as these purposes guide the assessment process. Still, little is known about teachers' assessment purposes. The aim of this study is to identify and describe the different purposes of assessments that Civics teachers…

The broad approach to using Generative AI in K-12 schooling focuses on identifying risks and productivity gains rather than the more complex issues of transformational change. As a response, this study examined how school leaders considered Gen AI transformation within their disciplines. Ten subject leaders were interviewed about their pedagogical…

The study determined teachers' knowledge of key issues such as classroom assessment, teaching process and assessment procedure in school-based assessment (SBA). It determined the level of SBA implementation in the classroom environment, teaching processes and assessment procedures in Ondo State secondary schools. These were to improve assessment…

Across multiple countries the term "big ideas" of mathematics has become a construct advocated as important for teachers' mathematical knowledge. Indeed, several policy or position statement documents about math learning in the United States (U.S.) have stated that "big ideas" of math is a crucial construct for teacher…

Constant teacher training and up-dating is fundamental to provide quality teaching and learning. Digital competences are among the skills that teachers must acquire in order to improve the teaching and learning processes. The aim of the present study was to review the scientific production of the last five years regarding teacher digital…

Background and Context: Computing education is expanding, while the teaching of algorithms is less well studied. Objective: The aim of this study was to examine teachers' pedagogical content knowledge (PCK) for teaching algorithms. Method: We conducted semi-structured interviews with seven computer science (CS) teachers in upper secondary…

Attitude toward technology integration and TPACK have been found to influence technology integration. However, little research has been dedicated to examining the relationship between them. This paper reports on a study that investigated the relationship between mathematics teachers' attitudes and TPACK for 125 participants from Dar es…

In this paper we report on a Learning Study (LS) focused on the teaching and learning of the economic concept of price. Cycles of action research informed by the variation theory of learning were undertaken by a group of secondary school teachers facilitated by the authors over a period of nine weeks. As researchers and facilitators, we were…

This descriptive study assessed technological, pedagogical and content knowledge (TPACK) competency among life sciences teachers in rural and marginalized schools. The study was guided by Koehler and Mishra's (2006) TPACK framework as its theoretical lens. Data gathered through questionnaires from 235 teachers in the Eastern Cape province, South…

Technology-based teaching and learning has been one way to improve students' achievement. However, some teachers are still unaware of how technology can be used to enhance teaching and learning, and they are also hesitant to use technology. This paper investigates how secondary school teachers understand and integrate technology to teach…

This study investigates what mathematicians, who teach academic mathematics courses to secondary school mathematics teachers, want to teach them about the discipline of mathematics. Data sources included interviews with five research mathematicians. The data analysis revealed that expanding teachers' knowledge about the discipline of mathematics…
