The logistics and cost of running large class tutorials to improve learning for students in high enrolment courses raise questions about whether the associated effort and cost are worthwhile. The option to replace these class activities with online homework with its promise of built-in feedback is attractive. Using an activity theory lens and an…

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…

This study explored the perceived benefits and challenges that Natural Sciences teachers experience when using blended teaching in Smart Schools. This qualitative research focused on public township schools with challenging socio-economic contexts in the Gauteng Province, South Africa. A non-probability purposive sampling method was followed. The…

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…

Information and communication technology (ICT) competences are among the most important requirements to effectively teach mathematics and science in today's classrooms. Teacher educators in the Southern African Development Community (SADC) region have prioritised ICT competences for pre-service teachers (PSTs) to effectively select suitable…

Although there is a lot of interest in the development of computational thinking (CT) and the benefits it could have for every student, integrating it into science classrooms may be more difficult than traditional teaching. This can be very challenging for South African science teachers. Thus, there is an increasing need to prepare teachers and…

The use of guided inquiry-based learning (GIBL) in a manner designed to challenge individual students' unscientific conceptions of science, has been researched widely. However, few (if any) studies have investigated the implementation of GIBL in a manner designed to challenge the fundamental patterns of students' context-dependent unscientific…

This study investigated the extent to which the proposed Factory of Ideas (FOI) teaching approach impacted on students' understanding of energy based on their prior knowledge. The FOI is a didactic approach that, unlike the classic cognitive conflict approach, employs a variety of activities to offer students a scientific conception for comparison…

Research findings show that inquiry-based science education has positive effects in improving learning of both science content knowledge and scientific inquiry (SI) skills. As a result, various science curricula, including that of Namibia, recommend the use of an inquiry-based approach in science teaching. However, the implementation of an…

The purpose of this study was to assess how the Inquiry Based Learning approach supports the development of students' academic language proficiency in invertebrate systematic. The study was framed by Halliday's sociolinguistic approach to learning. A total of 50 classroom observation sessions at 10 schools were conducted: 10 before and 40 after…

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…

Pedagogical content knowledge is considered a valuable knowledge base for all science teachers. Thus, promoting its development in all pre-service teacher programmes including a short 1 year Physical Science postgraduate certificate in education (PGCE) course is desirable. This paper focuses on the comparison of topic-specific pedagogical content…

Research in the past decades has repeatedly revealed that first year university students struggle to understand two-dimensional projectile motion concepts. In contrast to high school, projectile motion frequently makes use of components and it requires at least a basic understanding of trigonometry concepts. To follow the lessons and generate…

Within the science education community, it is widely accepted that quality science instruction is focused on knowledge construction and inquiry. The Ghanaian education system has many hallmark issues that inhibit such instruction, however, including a pervasive teacher-centred pedagogy, lack of laboratory materials, and minimal support systems for…

Effective teaching of physics requires the use of well-designed and diversified instructional tools such as multimedia throughout the teaching and learning process. The main objective of this study was to investigate the effectiveness of Physics Educational Technology (PhET) simulations and YouTube videos to improve the learning of optics in…
