Research output: Chapter in Book/Report/Conference proceedingConference contributionAcademic


In this paper we describe a highly interactive touch-based application to teach the basics of trigonometry to secondary school students. The application, called Ziggy, lets students “touch” and “push” triangles, dynamically modifying the shape and size, and observe the effect on the angles, sides and the trigonometric ratios. An early version of Ziggy has been tested in small-scale experiments in the classroom.
