Abstract
We describe and illustrate activities in a modelling challenge where secondary students learn and apply modelling
techniques to real life problems identified by themselves. A two‐day workshop format designed for this purpose has
featured for a number of years as the AB Paterson College Mathematical Modelling Challenge, in Queensland
Australia. Within this program, small teams of year 10/11 students identified their own modelling context, articulated
specific questions, conducted and reported on their subsequent modelling activity verbally and through poster
construction. The chapter describes and illustrates the structure and conduct of the program, including the introduction
to modelling provided to the students, content from selected projects, and mentor observations on characteristics and
outcomes. Evaluation of the program contains an internal dimension involving assessing the outcomes of student activity
in terms of recognised modelling criteria, and an external dimension considering the robustness of the program in terms
of its operation across parallel groups with different mentors, and its consistency from year to year in the outcomes
produced.
