Inquiry-based practical work (IBPW) is one of the innovative instructional strategies in science education. Science teacher preparation programmes play a role in preparing preservice teachers to facilitate IBPW in classrooms located in different school settings, including multiple-deprived classrooms. The adverse conditions against the successful implementation of IBPW found in multiple-deprived classrooms provide problems that preservice teachers will have to solve in their future classrooms. It is against this background that this study explored how preservice science teachers used computational thinking as a problem-solving strategy when facilitating IBPW in multiple-deprived classrooms. Using a single-case exploratory study, the experiences of 16 preservice physical sciences teachers were elicited through lesson planning, simulated teaching, and reflection. The data collected were analysed through thematic-content-analysis techniques. Findings indicate how through the use of computational thinking, participants were able to solve problems that had the potential to inhibit the implementation of IBPW.
This study used the community of inquiry (CoI) framework and the affordances of Internet of things (IoT) to explore how the faculty of education of a rural campus of a university transitioned from face-to-face to online modes of instruction. In this qualitative interpretive study, data were collected through open-ended questionnaires from four purposely selected teacher educators and five final-year bachelor of education preservice teachers. Thematic content analysis techniques were used to analyze the data collected. The findings indicated the tensions experienced by the teacher educators as they negotiated the limited IoT affordances to ensure effective teaching, cognitive, and social presence in the newly formed online classrooms. Some of the tensions included the choices that were made on whether to use synchronous or asynchronous modes of instruction and the selection of effective communication modes. The teacher educators used a combination of the official learning management system (LMS) tools of the university and a social media platform as way of navigating the limited 4IR environments experienced by the preservice teachers.
The closing of schools due to Covid-19 has brought a dimension of uncertainty into STEM education. Despite the closing of schools due to the need to observe physical distancing, some schools have found ways to continue teaching and learning on virtual platforms enabled by increasingly pervasive fourth industrial revolution environments. In this study, the teaching of Ordinary level mathematics and science in pursuit of STEM education goals as enabled by the Internet of Things (IoT) in online classrooms was therefore, explored. Using an interpretive case study, relevant data were collected from two mathematics and three science teachers during semi-structured interviews. These participants communicated their experiences in transitioning from face-to-face to online classrooms as they worked to promote STEM education during the Covid-19 pandemic. The findings reveal teachers’ experiences of this transition and their selection of particular Web 2.0 tools to establish online classrooms. Notably, mobile instant messaging tools proved to be a popular option for being cheap, user-friendly, temporal, and multimodal. The findings also revealed that teachers struggled to adapt the hands-on activities to suit online teaching resulting in the use of teacher-centred approaches.

The prioritization of quality education, especially in science and in mathematics, positions effective teaching and learning as a major school leadership goal. Effective curriculum implementation hinges on power dynamics in schools; this puts distributed leadership in the spotlight. Heads of departments (HoDs) are important role players in the distributed leadership structures of schools. This qualitative case study explored the roles of HoDs in four South African high schools to determine how opportunities were created for teaching and learning science and mathematics in the context of distributed leadership. Unstructured interviews were conducted with 13 participants. The findings show that, in distributed leadership structures, HoDs in science and mathematics played the roles of instructional leaders; school-based subject and classroom specialists; and that they were accountable for learner performance in their departments. Their actions supported other players in school leadership, including teachers in the classroom and principals, to improve teaching and learning through distributed leadership structures. We recommend that further studies explore and compare how HoDs navigate the complexities of their roles in different school contexts.
Practical work is pivotal for the development of important skills inherent to science, technology, engineering, and mathematics (STEM) education. Through practical work, learners engage in skills that include critical thinking, problem-solving, and inquiry-based learning, which are important outcomes of STEM education. Given the rise in significance of remote learning as reinforced by the COVID-19 pandemic, there is a need to reimagine the facilitation of practical work for learners. This paper uses the preferred reporting items for systematic reviews and meta-analyses (PRISMA) qualitative research design, an interpretive paradigm, and a mix of connectivism and community of inquiry (CoI) frameworks to explore the facilitation of STEM education practical work in remote classrooms. A systematic meta‑analysis of purposively selected papers using the preferred items, techniques of identification, screening, eligibility, and inclusion, and published between 2017 and 2021, was conducted. The following key words were used to conduct a search using Google Scholar: STEM practical work + STEM education in remote classrooms + Practical work in remote classrooms + STEM education in online classrooms + STEM education in virtual classrooms + Virtual practical work + Teaching STEM and COVID-19 + Practical work and COVID-19. Fifty papers were identified, of which fifteen were included in the study. Thematic content analysis techniques were used to analyze the papers. Five strategies to facilitate STEM practical work in remote classrooms were identified and the findings point to the prospects and future directions of practices in facilitating practical work for learners remotely.
