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…

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…

For efficient and effective pedagogical interventions to address Uganda's alarmingly poor performance in Physics, it is vital to understand students' motivation patterns for Physics learning. Latent profile analysis (LPA)--a person-centred approach--can be used to investigate these motivation patterns. Using a three-step approach to LPA, we sought…

The world we live in is increasingly multimodal, necessitating multiliteracy for learners to engage meaningfully with knowledge and skills. While verbal language is the primary medium for constructing, communicating and learning scientific knowledge and concepts, visuals can help learners to gain knowledge that they may not develop from verbal…

In recent years, the notion of equity has become increasingly prominent in mathematics education, in relation to pedagogy and the opportunities provided for learners to identify themselves as successful mathematics learners. Different pedagogies have been shown to promote equity and access to mathematics in different ways. However, teacher…

Drama is used to build knowledge and understanding in science as part of a socio-linguistic, constructivist approach. Role-plays, where learners act as analogues for components and processes, help access abstract ideas. However, a problem restricting many science teachers using these approaches has been that they lack sufficient pedagogical…

In this paper we focus on how South African students' ideas about the human body are constituted in their descriptions of three different scenarios involving the pathway of a sandwich, a painkiller and a glass of water through the body. In particular, we have studied the way in which the students transferred ideas between the sandwich and the…

This article reports an exploratory multi-case study on how science teachers understand and envisage addressing learners' misconceptions about electric circuits. Four teachers from schools in and around a large South African city participated in the study. An open-ended questionnaire was designed in a novel way, questioning teachers about wrong…

The international community looks towards Education for Sustainable Development (ESD) to address global problems such as environmental degradation, poverty and ill-health. This article focuses on the integration of ESD into science lessons. It reports Junior Secondary School (JSS) science Teachers' perceptions of the ESD concept; its integration…
