Abstract
In the last few years there has been a growing research interest in school mathematical modelling. However, most of the previous studies do not consider the use of technological tools. The study explains how to use a specific technological tool to deal with a mathematical modelling problem, namely A Ferris wheel case. The problem required secondary school students to construct linkage the concepts of trigonometry, circles, velocity, and distance. We propose a step-by-step process for solving this mathematical modelling problem using the Geometry Expression. Subsequently, the result obtained by technological tool is compared with the results obtained by paper pencil calculation method. At the end, we provide the strength and the weaknesses of using this technological tool.
