Ndlovu, Williams; Pournara, Craig; Mwakapenda, Willy – African Journal of Research in Mathematics, Science and Technology Education, 2019
In this article, we report on findings from a study that explored perspectives of Grade 10-12 learners from two rural secondary schools in the Eastern Cape Province in South Africa on the nature of mathematics prior to and at the end of a year-long mathematics mentorship programme. We use Ernest's (1994) orientations about the nature of…

Malcolm, Stephen Andrew; Mavhunga, Elizabeth; Rollnick, Marissa – African Journal of Research in Mathematics, Science and Technology Education, 2019
Stoichiometry, which deals with the quantitative aspects of Chemistry, is a topic students find challenging and which teachers struggle to teach. South African students' performance in stoichiometry in the final matriculation examinations has led to calls for the topic to be taught better and highlighted the need for teacher professional…

Tap, William D.; Mtetwa, David K.; Vere, Joseph C. – African Journal of Research in Mathematics, Science and Technology Education, 2019
This paper reports on some aspects of an investigation on the impact of an instructional approach aimed at generating and maintaining students' interest in mathematics for secondary school students in displaced and re-settled communities in South Sudan. Two groups of Grade 11 students, an experimental group (E-group) and a control group (C-group),…

Botha, Hanlie; van Putten, Sonja – African Journal of Research in Mathematics, Science and Technology Education, 2018
Mathematical literacy (ML) is a compulsory subject in South Africa for those learners who choose not to do mathematics to Grade 12 level. ML is designed to enable a learner to become a self-managing person by providing opportunities to analyse and solve real-life problems through the mathematisation of contextual situations. The subject thus lends…

Chani, Fungisisai; Ngcoza, Kenneth Mlungisi; Chikunda, Charles; Sewry, Joyce – African Journal of Research in Mathematics, Science and Technology Education, 2018
Chemical equilibrium is one of the most important yet difficult topics to teach. The purpose of this study was to examine how two science teachers experienced the mediation of and how they mediated learning of this topic, chemical equilibrium, to high-achieving students. Data were collected using semi-structured interviews, lesson observations and…

Price, Charmaine; van Jaarsveld, Pieter – African Journal of Research in Mathematics, Science and Technology Education, 2017
This article reports on using open-response questions to reveal the level of, and change in, conceptual understanding of a small sample of Grade 11 learners of trigonometry in a South African high school. The investigation used learner response sheets in a regular classroom with the teacher as researcher. Combining the idea of concept image and…

Mhlolo, Michael Kainose – African Journal of Research in Mathematics, Science and Technology Education, 2016
The concept of pattern recognition lies at the heart of numerous deliberations concerned with new mathematics curricula, because it is strongly linked to improved generalised thinking. However none of these discussions has made the deceptive nature of patterns an object of exploration and understanding. Yet there is evidence showing that pattern…

van Zyl, Sukie; Mentz, Elsa; Havenga, Marietjie – African Journal of Research in Mathematics, Science and Technology Education, 2016
As part of curriculum changes in South Africa, an introductory programming language, Scratch, must first be taught before switching to the well-established teaching of Delphi. The nature of programming in Scratch is considerably different from that in Delphi. It was assumed that the teaching of Scratch as introductory programming language could…

Kavai, Portia; de Villiers, Rian; Fraser, William; Sommerville, Jaqui; Strydom, Nina – African Journal of Research in Mathematics, Science and Technology Education, 2015
In Life Sciences education internationally, including South Africa, the study of animal and organ morphology has traditionally involved dissections since the early nineteenth century. The major purpose of this study was to investigate how the engagement of learners with animal organ dissections may influence the development of problem-solving…

Mbonambi, Martin Sipho; Bansilal, Sarah – African Journal of Research in Mathematics, Science and Technology Education, 2014
The purpose of this study was to explore and compare the proficiency of Grade 11 Mathematics and Mathematical Literacy (ML) learners in solving two problems based on the temperature conversion formula. The first was a result-unknown problem that asks for the result of a formula for a given input. The second was a start-unknown problem in which the…

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…

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…

Kazeni, Monde; Onwu, Gilbert – African Journal of Research in Mathematics, Science and Technology Education, 2013
The study aimed to determine the comparative effectiveness of context-based and traditional teaching approaches in enhancing student achievement in genetics, problem-solving, science inquiry and decision-making skills, and attitude towards the study of life sciences. A mixed method but essentially quantitative research approach involving a…

Msimanga, Audrey; Lelliott, Anthony – African Journal of Research in Mathematics, Science and Technology Education, 2012
In this paper we report on the process of argument construction in whole class discussions and how this was used by participants as a tool for joint meaning-making. The study draws on Vygotsky's view of learning as the active construction of knowledge and on theories of argumentation. Most previous research in South African science classrooms has…

Mudaly, Vimolan; Rampersad, Rajesh – African Journal of Research in Mathematics, Science and Technology Education, 2010
This paper is based on a study which explored the conceptual understanding of Grade 11 mathematics learners of graphical functional relationships, in particular their understanding of the Cartesian plane, notation, symbols and graphical terminology. The National Curriculum Statement (NCS) for Grades 10-12 in mathematics stipulates functional…
