This study aimed at exploring the understanding of concept inventories for classroom assessment by physics tutors and pre-service teachers in selected diploma teachers' training colleges in Tanzania. The study employed a qualitative research approach and a case study design. Eight physics tutors and 20 second-year pre-service physics teachers from…

This study investigated children's knowledge of the addition of fractions with unlike denominators. It focussed on the strategies used by children to add fractions with unlike denominators. A cross-sectional survey of Grade 8 children in schools in two districts in Ghana was used. A test on the addition of fractions with unlike denominators was…

Gender inequality is strongly linked with poor performance in science and mathematics for female students in secondary schools owing to socio-economic and cultural issues as well as learning strategies. According to the Certificate of Secondary Education Examination results of 2021 in Tanzania, the failure rate for female students was higher than…

This paper reports on a study that explored the subject and pedagogical content knowledge displayed by high school mathematics teachers in the Khomas education region in Namibia. The study was based on a quantitative approach using a survey design. A stratified random sampling method was used to select the participants in all the four school…

Problem-based learning (PBL) is considered to be an effective teaching and learning strategy as it leads to longer retention of concepts learnt, improves problem-solving skills and enhances critical thinking. However, teachers often find it difficult to implement as they do not receive guidance during their initial training. A professional…

This study sought to analyse, using the Mathematics Discourse in Instruction framework, teachers' explanatory talk when introducing standard units of length in standard 4 in Malawi. The study analysed teachers' use of content and pedagogical practices for introducing standard units of length and how that made the concept of standard units of…

In physics education, assessments address various forms of scientific knowledge. Most of the existing test instruments emphasise the assessment of content knowledge. These tests fail to measure the epistemic aspects of science. Thus, assessing epistemic knowledge is a theme that demands investigation. This study applies Rasch analysis to help…

It has recently been suggested that pedagogical content knowledge (PCK) has a concept-specific nature, beyond the topic-specific level of PCK. This paper reports a case study of three pre-service teachers' reported PCK about three fundamental concepts within the topic of electrostatics, namely electrostatic force, electric field and electric field…

This paper reports on a study conducted with Grade 11 learners as participants, in four public high schools in a rural district of the Eastern Cape Province of South Africa. The central objective was to investigate the mathematical discourses of Grade 11 learners related to the word, algebraic and graphic representations of asymptotes of the…

This paper is about using a 'Two-Eyed Seeing' approach as the process of co-learning for incorporating elements of indigenous knowledge into school science teaching. Two groups of 150 Form 3 integrated science learners drawn from six high schools in Mutare, Zimbabwe, comprised the study sample. One group of learners, the control group, was taught…

There is a scarcity of studies that focus on how South African high school physical sciences teachers are grappling with chemical laboratory safety (CLS). This is despite the fact that the Curriculum and Assessment Policy Statements in the South African school system increased emphasis on laboratory activities in the physical sciences. Department…

Against the background of the low mathematical performance of South African learners in international panel studies, there is an urgent need to improve mathematical education. In particular, the curriculum and its structure raise questions. It is logical that the prescribed curricula should align with learners' developmental trajectories. Given…

In this paper we probe prospective mathematics teachers' thinking as displayed in their solutions to a geometry content knowledge-based task. Geometry content knowledge is examined in terms of connections made by these prospective teachers between the geometric configurations and the geometric principles established through visualization and…

Previous research on students' difficulties in learning chemical equilibrium has shown that students hold misconceptions about this topic, and this often results in unintended learning. However, recent developments in human learning from the behavioural sciences perspective indicate that students' difficulties in learning are much more than…

The Department of Basic Education in South Africa has identified factorisation as a problem area in Mathematics teaching. Learners in earlier grades are exposed to mathematical tasks, involving concepts, such as factors of integers, fractions, equivalent fractions and prime numbers, that are easier to solve when the divisibility rules are applied.…
