Abstract
Digital technologies have afforded many possibilities for the teaching and learning of mathematics and this has become a major area of research in Mathematics Education. A particular class of digital tools, known as Dynamic Geometry Software (DGS), allows mathematical concepts to be explored in a visual – dynamic way. In a DGS, geometrical figures or diagrams can be dragged and manipulated thus making them dynamic. The ‘dynamism’ of these figures provides opportunities to students to experience mathematical properties very differently from static figures which they generally experience in a traditional geometry class. In this article, we shall illustrate how middle school students experienced the angle sum property of a triangle, a fundamental geometrical idea, using GeoGebra, an open source DGS. A dynamic geometry software is also referred to as a dynamic geometry environment (DGE).
