This study surveyed 19 chemistry teachers' stoichiometry pedagogical content knowledge (SPCK) in Ijebu Ode local government area of Ogun state, Nigeria using Malcolm's Physical Science Teachers' SPCK test. The qualitative data were transformed to scores, which revealed the level of chemistry teachers' knowledge of students' prior knowledge,…

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 examined pre-service science teachers' pedagogical content knowledge (PCK) about seasons. The framework of this study was based on the Refined Consensus Model (RCM), and pre-service teachers' topic-specific PCK was also discussed in two dimensions: personal PCK (pPCK) and enacted PCK (ePCK), which are included in this model. The pPCK of…

Pedagogical content knowledge (PCK) consists of a set of understandings, knowledge, skills, and dispositions necessary for effective performance in specific teaching and learning situations. Using Scopus, EBSCO, and Web of Science databases, the study examines the progress of the PCK in science teacher education between 2011 and 2021. In total, 59…

Artificial intelligence (AI) has made remarkable strides in recent years, finding applications in various fields, including chemistry research and industry. Its integration into chemistry education has gained attention more recently, particularly with the advent of generative AI (GAI) tools. However, there is a need to understand how teachers'…

Active-learning instructors are more effective when they use pedagogical content knowledge (PCK) to anticipate, interpret, and respond to student thinking. PCK is topic-specific and includes knowledge of student thinking (e.g., common difficulties) and knowledge of instructional strategies (e.g., effective learning tasks). Currently, we know…

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…

Background: Effective science teaching requires a specialised body of knowledge. Researchers have recognised the importance of understanding the incoming knowledge that pre-service science teachers (PSTs) bring to their initial teacher education. However, although many studies have focused on PSTs' declarative knowledge or the knowledge that…

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…

While the distinction between academic disciplines and school subjects has received some attention, the question of which subject matter content knowledge (CK) teachers need as a foundation for initial teacher development has been raised. In science education, Teacher-related Science Content Knowledge (TerSCK) has been conceptualized to model the…

This study examines how pre-service science teachers integrate technology into the design of learning activities, paying particular attention to types of technology integration, cognitive demand, scientific research skills, and TPACK. A mixed methods approach was used to analyze 49 learning activities designed by pre-service physics, chemistry,…

To comprehend the perspectives of school and university mentors in evaluating practicum experiences based on educational reform, this study aimed to investigate the feedback, within the framework of pedagogical content knowledge, provided by two cooperating teachers and a university supervisor to preservice teachers. Observation and document were…

Questioning is a critical instructional strategy for teachers to support students' knowledge construction in inquiry-oriented science teaching. Existing literature has delineated the characteristics and functions of effective questioning strategies. However, attention has been primarily cast on the format of questioning like open-ended questions…

The intervention programmes have a direct influence on teachers' knowledge of teaching different topics. This paper focuses on how Grade 8 natural science teachers' knowledge developed during an intervention programme. Eight schools were selected to participate, and 25 Grade 8 Natural Sciences teachers from Gauteng province participated. Data were…
