Vince Geiger, Rhonda Faragher and Trevor RedmondThis paper considers the potential of Computer Algebra Systems (CAS) to enhance the processes associated with mathematical modelling and application tasks. In doing so, the role of technology in the cyclical development of mathematical models will be theorised. Finally, a theoretical framework will be outlined for a classroom-based investigation into the implementation of CAS technologies into classroom contexts where mathematical modelling and applications are a focus.
