Smith, Charles Raymond; Julie, Cyril; Gierdien, Faaiz – South African Journal of Education, 2020
In this article we examine the nature of inter-semiotic and intermodal construction in the exposition of a solution for a geometry rider. In the tradition of hermeneutic phenomenology, this case study involved an exploration of the oral discourse and visual texts used in a mathematics lesson. This research was intended to contribute to the…

Bansilal, Sarah; Naidoo, Jayaluxmi – South African Journal of Education, 2012
This article reports on a qualitative, interpretivist study that focused on the use of visualisation and analytic strategies by Grade 12 learners when working with problems based on transformation geometry. The research was conducted with 40 learners from a Grade 12 class at one high school in the north Durban area of Kwazulu-Natal. Participants…

Ono, Yumiko; Ferreira, Johanna – South African Journal of Education, 2010
We consider the professional development of in-service teachers and review traditional development efforts that have been used in the past. An alternative form of professional development using Japanese lesson study is proposed and discussed as a possibility. A case study involving the Mpumalanga Secondary Science Initiative, where lesson study…

Kazima, Mercy; Pillay, Vasen; Adler, Jill – South African Journal of Education, 2008
We report on two case studies in which we investigated mathematics for teaching. We were interested in the mathematical knowledge teachers need to know, and know how to use, in order to teach mathematics well. The two case studies focused on the teaching of probability in Grade 8 and the teaching of functions in Grade 10. We discuss the…

Kotzé, Gary – South African Journal of Education, 2007
In this investigation I focused on a process of activities of a particular group of teachers and learners. Basic skills in mastering mathematical concepts were addressed. The focus was on concept formation in the geometry classroom. The methodology involved an educational case study as a form of inquiry to investigate spatial sense. Evidence was…
