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…

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…

This study addresses suggestions for analyzing science teachers' pedagogical content knowledge (PCK) components and their interactions and these suggestions are expected to facilitate the analysis of science teachers' PCK, resulting in more accurate representations of PCK. Knowledge of the science curriculum, knowledge of students' understanding…

National reform documents all around the world issue an urgent need for the development of integrated STEM (Science, Technology, Engineering, and Mathematics) curricula. With the emphasis on the development of STEM curricula, there is also a need for improving teachers' and future teachers' conceptions of the integrated STEM approach. This study…

The study assessed, designed, developed, validated, implemented, and evaluated the effects of the e-training package on TPACK. The study was conducted at Bukidnon State University from 2021-2022. Using Research and Development, an e-training package on TPACK involved Content Knowledge, Technological Knowledge, and Pedagogical Content Knowledge was…

Pedagogical content knowledge, PCK, a concept in teacher education requires additional focus and attention by pre-tertiary teachers to improve teaching and learning and learners' performance. The study adopted PCK model developed by Magnusson et al. (1999) to investigate senior high school (SHS) chemistry teachers PCK in teaching the concept of…

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…

Mechanistic explanations, aiming to disclose details of entities and their activities, employ the act of unpacking which, inherently and paradoxically, produces explanatory gaps--pieces of undisclosed, undetailed mechanistic information. These gaps, termed explanatory black boxes, are often perceived as counterproductive to the teaching of…

The study explored the influence of technology on science teachers' PCK and the benefits of that knowledge component on classroom practices. The study relied on science teachers teaching the various science subjects such as Biology, Chemistry, Integrated Science and Physics in Tamale Metropolis, Ghana. Sequential explanatory research design was…

This study investigated in what ways and to what extent the interactions between the components of pedagogical content knowledge (PCK) differ for junior high school science teachers with different levels of content knowledge. Data were collected from three science teachers through semi-structured interviews and classroom observations. The…

It is vital that upper secondary students gain a rich and deep knowledge of sustainability issues, as they will enter adulthood and working life within a short time. The students belong to a generation that will be intensely involved in managing several environmental issues to achieve sustainable development for our Earth. However, earlier…

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…

The purpose of this study was to, first, examine the potential of lesson plans (LPs) of preservice science teachers (PSTs, N = 631) as a source for gathering rich data on their pedagogical content knowledge (PCK) and, second, qualitatively describe PSTs' reasons for the level of data richness in their LPs on PCK. PSTs' handwritten LPs were…

Language is a fundamental tool for learning science. This study highlights the importance of teacher knowledge in utilising language as a tool for knowledge generation in the classrooms. This case study examines elementary teachers' development of declarative, procedural, and epistemic knowledge related to using language, particularly focusing on…

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…
