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…

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…

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…

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…

The aim of this research is to explore the system of knowledge of the Lebanese secondary physics teachers that affects the selection and integration of educational resources.

Teacher knowledge is vital to provide meaningful learning opportunities. In this case study, a secondary education teacher's knowledge about how to teach the concept of ecosystems from a river is explored. A category system drawn from the literature about science teacher knowledge was used for the analysis. Science teaching requires teachers to…

The early years of teaching are important for science teachers, but little is known about how science teachers develop professionally in their early years. This mixed methods study took a longitudinal view of the early years of teaching. Following 95 secondary science teachers over a 5-year period, this study examined the beliefs, pedagogical…

It is important for students to understand force concepts because they are central to learning physics and other sciences; however, students find it difficult to understand. There are calls for teachers to tap into their professional knowledge and develop beliefs that help them assist students comprehend the topic. To meet this challenge,…
