Education institutions globally, are increasingly driven to integrate innovative technologies in teaching spaces. While many studies have been conducted on e-learning, blended learning and m-learning, only a few studies have concentrated on the STEM preservice teachers' e-readiness for using online multimodal teaching methods in developing…

In South Africa, there is a strong recognition of the affordances of information and communications technology (ICT) in science teaching and learning. A key indicator for the effective use of ICT is the technological pedagogical content knowledge (TPACK) of teachers with TPACK-Practical (TPACK-P) being an important iteration related to teacher…

Research on mathematical equivalence, and to some extent, on number structure in early grade mathematics, has shown that most students at primary and secondary levels understand these concepts instrumentally rather than relationally. The study reported in this paper uses a design research approach to explore both mathematical equivalence and…

The development of statistical literacy has become a key outcome of mathematics curricula in various countries. The purpose of the study was to explore primary pre-service teachers' (PSTs') knowledge of aspects of measures of central tendency, which is a central concept in statistical literacy. The 183 PSTs' written responses to four tasks were…

Teachers' pedagogical content knowledge (PCK) has the potential to influence lesson planning, teaching and students' academic performance in science. Since PCK is embodied in lesson planning (as planned PCK), this study employed the multiple-case design to describe in-depth the biology teachers' profiles of planned topic-specific PCK (plTSPCK) for…

Topic-specific pedagogical content knowledge (TSPCK) enables teachers to transform pedagogically difficult content for specific science topics into forms more easily understood by learners. In science teaching, there is evidence pointing to poor learner performance in key chemistry topics such as stoichiometry. This paper reports on the changes in…

This research examines the relationship between high school teachers' understanding and reported practices of inquiry-based pedagogy (IBP) in science classrooms in Nigeria. A sample of 11 science teachers from an education district in Lagos, Nigeria, was chosen for this case study. Data were collected using a semi-structured questionnaire, which…

The mole concept is one of the fundamental concepts in chemistry. However, a number of studies carried out in various countries have shown that teachers and learners face many difficulties in teaching and learning the concept. One of the underlying sources of teaching and learning difficulties of the mole concept identified in literature is the…

The divide between theory and practice is an enduring challenge commonly attributed to disconnection in teacher knowledge between 'knowing what to do' (planning) and 'doing what you know' (enacting in class). We re-visited this divide from the new perspective of pedagogical content knowledge with the purpose of examining the ways in which…

This study aimed to understand teachers' classroom practices using computer-based simulations (CBS) when teaching electrolysis. The study was framed by the Consensus Model of Pedagogical Content Knowledge. Convenience and purposive sampling were used to select three experienced chemistry teachers from three schools in Eswatini (Swaziland).…

Learners come to class with a wealth of knowledge. Working with learner prior knowledge (LPK) is the foundation upon which new concepts get their meaning. Yet some teachers find interacting with LPK complex. Reflecting on practice, particularly within a professional learning community (PLC), has resulted in improvements in teaching. The focus of…

The purpose of this study was to explore whether chemistry lesson sequences can indicate the level of teachers' pedagogical content knowledge (PCK). The sequencing of lessons for teaching chemical bonding is taken as the case for this study. The correct sequencing of concepts in teaching chemical bonding is key to learners' conceptual…

Chemical equilibrium is one of the most important yet difficult topics to teach. The purpose of this study was to examine how two science teachers experienced the mediation of and how they mediated learning of this topic, chemical equilibrium, to high-achieving students. Data were collected using semi-structured interviews, lesson observations and…

This paper reports the results of a study that compared two approaches to developing in-service teachers' subject matter knowledge and strategies for teaching nature of science. A treatment post-test only quasi-experimental research design was used. One group of in-service teachers (n = 15) was taught using what is called a capsular approach. In…

This case study explored the development of two pre-service teachers' subject matter knowledge (SMK) of electromagnetism while integrating the use of concept maps (CM) and collaborative learning (CL) strategies. The study aimed at capturing how these pre-service teachers' SMK in electromagnetism was enhanced after having been taught SMK in a…
