Building maths modelling skills: 2023 challenge winners

Media release 5 minute read

Brisbane Boys’ College and Sydney Boys High School will represent Australia in this year’s International Mathematical Modeling Challenge (IM2C).

The Australian judging panel awarded Brisbane Boys’ College the Outstanding Achievement prize and Sydney Boys High School the Meritorious Achievement award. The international results will be announced in late June.

Coordinated in Australia by the Australian Council for Educational Research (ACER), the IM2C sees students use their research, mathematical and creative abilities to develop a mathematical model to address a real-world problem.

The challenge this year was to decide the best use of a parcel of land available for development, considering short and long-term benefits and costs. Teams of up to four students had five consecutive days to create mathematical models and submit a report of up to 20 pages, a summary and a letter to community leaders and business planners with their recommendation.

Dr Kristy Osborne, ACER Research Fellow and IM2C Australia Director, was impressed with the students’ mathematical modelling work.

“The real world is complicated and messy. Solving problems based on real-world scenarios is challenging as there are many ways to solve problems. It’s exciting to see all the creative ways the teams use mathematics to solve the problem,” Dr Osborne said.

“Students need to consider the key factors in a problem, and how to measure and model these factors. They need to realise the limitations of any model they create. Having the opportunity to apply mathematical skills to a real-world problem, in a team environment, is a challenging and often rewarding experience for many students. The problems in IM2C are designed to be open-ended, and students are encouraged to be creative with the techniques they employ to solve the challenge problem,” she said.

The judges chose 11 finalists from 56 teams representing the 18 schools in the challenge.
