COVID-19 posed formidable challenges to the teaching and learning of subjects with abstract concepts such as Science, Technology, Engineering and Mathematics (STEM). The study explored how STEM teachers transformed their pedagogical practices as an integral part of the transition to online teaching and learning in response to COVID-19 and further examined the effectiveness of online teaching and learning. The study adopted an exploratory descriptive survey design and involved purposively selected STEM teachers from schools operating under the auspices of the Association of Muslim Schools. The Technological Pedagogical Content Knowledge (TPACK) framework underpinned the study. Quantitative data was collected through the administration of a Likert scale instrument. Data was analysed using inferential and descriptive statistics. Findings revealed that COVID-19 essentially compelled teachers to make a transition to online teaching and learning resulting in a concomitant profound impact on their pedagogical practices. Teachers provided various perspectives on the key modalities adopted to navigate online teaching and learning on virtual platforms in an attempt to ensure sustainable, equitable and inclusive teaching and learning. Implications for broadening educational pathways to STEM education through online teaching and learning on virtual platforms and sustainable teacher professional development on technology integration in teaching and learning are discussed.

In the analysis of the South African NSC diagnostic reports, the Department of Education prepared areas of learners’ struggle have proved to repeat themselves from 2017 to 2020. The classroom practices of Life Sciences teachers, focusing on teacher knowledge, were observed in a sample of schools in the province of Gauteng, South Africa. The investigation aimed to investigate these practices of Life Sciences teachers and consequently diagnose teaching difficulties. Data was collected through interviews and observations in a multi-case study approach and analyzed using Mudau’s (2016) Classroom Practice Diagnostic Framework. This study reveals that teachers’ classroom practices contribute to the teaching difficulties they experience when considering teachers’ knowledge of the Life Sciences content, the teaching context, and learner understanding.

The importance of the enactment of formative assessment as a pedagogical tool in science teaching and learning cannot be over-emphasized. Teachers encounter pedagogical challenges when enacting formative assessment in science classrooms. These pedagogical challenges underscore the need to explore teachers' perspectives on pedagogical strategies used to enact formative assessment in science classrooms. This study examined grade 10 Physical Sciences teachers' perspectives on pedagogical strategies they adopted to enact formative assessment in science classrooms in diverse schools in South Africa. The empirical investigation invoked the sociocultural theory as a conceptual lens to provide insightful elucidation into the nature of teachers' perspectives on pedagogical strategies used to enact formative assessment in science classrooms. A generic qualitative research approach was employed. Data were collected through semi-structured focus group interviews and classroom observations. The study involved 12 purposively selected grade 10 Physical Sciences teachers as participants. The findings revealed that grade 10 Physical Sciences teachers adopted various pedagogical strategies when enacting formative assessment in science classrooms. However, meaningful enactment of formative assessment in science classrooms was largely hampered by a myriad of contextual factors such as class size and general lack of essential resources. It is recommended that teacher professional development interventions coordinated by the Department of Basic Education ought to make provision for meaningful opportunities to enhance teacher professional capacity required for coherent enactment of formative assessment as an essential tenet in science education. Theoretical implications for pedagogic innovation are discussed.
