Brodie, Karin; Sanni, Rasheed – African Journal of Research in Mathematics, Science and Technology Education, 2014
Much of the work on teacher knowledge suggests that content knowledge shapes pedagogical content knowledge, and in fact is primary in the relationship between the two forms of knowledge. In this paper we challenge this view, arguing from a situated perspective on knowledge and learning, that pedagogical content knowledge strongly shapes content…

Qhobela, Makomosela; Moru, Eunice Kolitsoe – African Journal of Research in Mathematics, Science and Technology Education, 2014
Teacher-centred strategies have dominated most physics lessons in Lesotho. This study attempted to understand the contributing factors for the choice of teacher-centred teaching instead of learner-centred teaching with the goal of informing a professional development programme designed to address this problem. The paper responds to the research…

Moyo, Partson Virira; Kizito, Rita – African Journal of Research in Mathematics, Science and Technology Education, 2014
Identifying an instructional tool for merging scientific and indigenous knowledge (IK) is problematic as there is no clear guidance on how this can be achieved. Argumentation is recommended as a possible integrative instructional theoretical methodology as it imbues notions of dialogue and persuasion, while at the same time embracing the…

Gierdien, M. Faaiz – African Journal of Research in Mathematics, Science and Technology Education, 2014
This paper reports on the initial stages of a small-scale project involving the use of "spreadsheet algebra programs" in the professional development of eight teachers from three township high schools. In terms of the education context, the paper draws on social practice theory. It then details what is meant by spreadsheet algebra. An…

Stott, Angela; Case, Jennifer M. – African Journal of Research in Mathematics, Science and Technology Education, 2014
Electronic tutors able to respond appropriately to a user's input have been shown to be effective in improving learning in a number of contexts. This study extends this research into the context of conceptual change during in-service science teacher workshops. Quantitative data were collected from 1,049 South African grade 12 physical sciences…

Gaigher, Estelle – African Journal of Research in Mathematics, Science and Technology Education, 2014
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…

Mhlolo, Michael Kainose; Schäfer, Marc – African Journal of Research in Mathematics, Science and Technology Education, 2014
Even though reflective symmetry is heavily embedded in the everyday, learners continue to experience challenges when they mathematize concepts from this informal/everyday context. In this article we argue that symmetry exists in nature, it can also be symbolized algebraically and it can be abstracted into the world of axioms and theorems. We…

Dinis da Costa, Daniel – African Journal of Research in Mathematics, Science and Technology Education, 2014
This article presents student-teachers' perceptions of spatial 3D-descriptive geometry education in Mozambique. To interpret a 3D object through 2D projections and vice-versa requires spatial abilities that are deemed crucial for learning in any spatially dependent discipline such as 3D-descriptive geometry, engineering and technical-vocational…

Mudaly, Vimolan – African Journal of Research in Mathematics, Science and Technology Education, 2014
Within the South African school curriculum, the section on graphical functional relationships consists of signs which include symbols, notation and imagery. In a previous article we explored the role visualisation played in the way learners understood mathematical concepts. That paper reported on the learners' fixation with the physical features…

Kurup, Raj – African Journal of Research in Mathematics, Science and Technology Education, 2014
An adequate understanding of the Nature of Science (NOS) has become increasingly important for science teachers in the context of the recent curriculum revisions being implemented in Grades R-9 in South African schools. This study explored the NOS conceptions and the influence of these conceptions on the classroom practice of two groups of…

Nsengimana, Théophile; Ozawa, Hiroaki; Chikamori, Kensuke – African Journal of Research in Mathematics, Science and Technology Education, 2014
In 2006, Rwanda began implementing an Outcomes Based Education (OBE) lower secondary science curriculum that emphasises a student-centred approach. The new curriculum was designed to transform Rwandan society from an agricultural to a knowledge-based economy, with special attention to science and technology education. Up until this point in time…

Kotoka, Jonas; Kriek, Jeanne – African Journal of Research in Mathematics, Science and Technology Education, 2014
The impact of computer simulations on the performance of 65 grade 11 learners in electromagnetism in a South African high school in the Mpumalanga province is investigated. Learners did not use the simulations individually, but teachers used them as an interactive demonstration tool. Basic concepts in electromagnetism are difficult to understand…

Tsanwani, Avhasei; Harding, Ansie; Engelbrecht, Johann; Maree, Kobus – African Journal of Research in Mathematics, Science and Technology Education, 2014
Under-performance in mathematics is a challenge in South African schools. The purpose of this study is to advance views expressed by teachers and learners on factors that facilitate learners' performance in mathematics. The participants in this research were educators and learners from historically disadvantaged schools from similar socio-economic…

Krishnannair, Anilkumar; Christiansen, Iben – African Journal of Research in Mathematics, Science and Technology Education, 2013
Conceptualization and the practice of alternative assessments in the context of general assessment practices in mathematics have wide-ranging significance to learning and teaching. Yet little is known about how South African teachers choose assessment tasks and how it links to their teaching. This paper reports on a case study of five grade 10…

Dempster, Edith R.; Stears, Michèle – African Journal of Research in Mathematics, Science and Technology Education, 2013
Traditional forms of assessment, mainly by written tests and examinations, cannot be said to be fair in a multicultural, multilingual environment. In South African public schools, home language is strongly associated with socioeconomic context, with both factors related to performance in traditional assessments. Children attending poor public…
