Teaching Harmonic Motion in Trigonometry: Inductive Inquiry Supported by Physics Simulations.

An argument is presented that applying trigonometric functions to model harmonic motion offers a rich scientific context to exercise mathematical modelling through inductive inquiry in trigonometry classes as well. The paper describes an activity that uses a physics simulation called 'Wave on a String' created by the PhET Interactive Simulations Project at Colorado University at Boulder, and is available on the internet. The activity's cognitive learning objectives fit into the scope of the proposed Australian mathematics curriculum that highlights the development of the skills of mathematical modelling, data collection, and analysis.
