The purpose of this study was to delve into the interaction between pre-service chemistry teachers' pedagogical content knowledge (PCK) and content knowledge (CK) while teaching electrochemistry. Two pre-service chemistry teachers enrolled in practice teaching course in chemistry education program participated in the study. All PCK components were…

This study examined the relationship between preservice teachers' Educative Teacher Performance Assessment (edTPA) scores, the most widely implemented preservice teacher performance assessment in the United States, and the pedagogical content knowledge (PCK) levels reflected in their edTPA portfolios. PCK is a specialized form of teacher…

Some researchers have investigated teachers' pedagogical content knowledge (PCK) concerning scientific practices. However, from a review of the literature on the PCK construct and its use for characterising teachers' knowledge of scientific practices, as well as from a discussion of possible interpretations that emerge from the derived construct…

College English teachers' pedagogical content knowledge (PCK) is subject to change in the transition from the teaching of General English (GE) to that of English for Academic Purposes (EAP). Underpinned by Grossman's four-dimensional model of PCK, this study aims to investigate the trajectory of PCK development among college English teachers…

STEM (Science-Technology-Engineering-Mathematics) education has received great attention in recent years not only for promoting interest and learning in these areas but also for encouraging children and young people to pursue careers in them. This research explored the effects of a STEM program in developing the primary pre-service teachers'…

The M.S. Chemistry -- Chemical Education Specialization program at South Dakota State University provides in-depth general chemistry coursework to in-service high school science teachers in a virtual format. The goal of the program is for the teachers enrolled to become more effective teachers while gaining content knowledge in chemistry; in…

This study reports mixed-methods research findings, which assesses the level of mathematics teachers' pedagogical content knowledge (PCK) in selected secondary schools of Zanzibar. A Likert-scale questionnaire related to PCK self-assessment was administered to 69 teachers, 12 of whom were observed three times during lesson delivery in their…

This study explored the potential impact of teaching outside of one's field of expertise. This longitudinal cross-case study examined the development of enacted pedagogical content knowledge (ePCK) among a group of in-field and out-of-field (OOF) physical science teachers during their first 3 years of teaching. The components of ePCK investigated…

Many science teachers leave the teaching profession during the first five years of practice resulting in a "greening" of the population. This phenomenon produces a high concentration of early-career teachers with low levels of pedagogical content knowledge (PCK). PCK is the ultimate measure for knowing the content one teaches and the…

In this study, a learning study was used to enhance prospective teachers' learning about how to teach a specific topic in mathematics or natural science to 4th-6th graders. It has been argued that participating in learning study can direct prospective teachers (PTs) towards the object of learning, and what needs to be enacted in teaching to make…

The aim of this paper is to bring the voices of teachers to the foreground and provide insight into the collective aspects of pedagogical content knowledge (PCK) development in primary schools, as perceived by science and technology teachers themselves. Through narrative inquiry in a retrospective and situated perspective, the narratives of the…

Given the scarcity of studies explicitly exploring the often tacit assumption that teachers' content knowledge (CK) is pre-requisite of pedagogical content knowledge (PCK), in this study, we draw on Shulman's conceptualization of these notions to examine their relation by content-aligning the CK and PCK measures. Toward this end, we analyzed data…

This study aimed to explore the pedagogical content knowledge (PCK) of preschool teachers. This multiple case study was conducted with the participation of two preschool teachers. In this way, two preschool teachers' PCK about science teaching was examined, and it was attempted to determine the underlying causes of their pedagogical…

Pedagogic Content Knowledge (PCK) is variously considered a useful framework, construct, model and tool to both understand and help form the knowledge base for teaching. There exists extant literature on the PCK of science. Building on this literature, this study aims to contribute towards an understanding of implementing curriculum reforms in…

Pedagogical Content Knowledge (PCK) is a powerful construct for examining the complexity of teacher knowledge. Together with teachers' moment-by-moment choices of action, it provides insight into teachers' knowledge and its influence on student learning. This paper investigates the PCK experienced by a senior secondary mathematics class during a…
