This presentation explores exponential modelling to address
big questions like population growth and magnetic field
changes, integrating diverse worldviews. Designed as a
low-entry, high-ceiling task, it engages Year 9 students using
CAS technology, fostering accessible yet deep mathematical
exploration. The task is adaptable for VCE Mathematical
Methods investigations, encouraging students to form
conjectures about real-world issues and their philosophical
implications. Through practical applications, students
develop critical thinking and connect mathematical models
to global challenges, enhancing their understanding of
exponential functions and their societal relevance. The
presentation highlights strategies to make complex modelling
inclusive, rigorous, and relevant across secondary education
levels.
Allason and Cathy will facilitate a session designed to help
teachers reflect on common challenges students face in
Mathematical Methods examinations.
Key takeaways:
1. Accessible Modelling: A low-entry, high-ceiling task
using CAS technology enables students at different level to
participate
2. Mathematical Investigation: Modifiable for VCE Methods,
encouraging conjectures linking math to worldviews.
3. Real-World Impact: Connects exponential models to
global issues, and comparing of worldviews, enhancing critical
thinking.
Drawing on patterns observed in previous exams, they will
highlight frequent errors and misconceptions they have
observe and ask delegates to share their insights. They will
provide strategies to support students’ understanding and
exam readiness. The session will include opportunities to
discuss how these insights can be applied in the classroom to
strengthen teaching and learning approaches for the 2026
cohort.
Key takeaways:
1. Teachers will gain insights into common errors and
misconceptions students encounter in Mathematical
Methods.
2. Practical advice and strategies will be shared to support
effective student learning and exam preparation.
3. The session will assist teachers in planning for 2026 with a
focus on addressing known areas of difficulty.
Remember:
Please bring copies of recent Mathematical Methods
examinations for reference.
Remember:
A TI CAS calculator will be used for the presentation but a
CASIO can be used to follow along.

(Year 11 to Year 12)
This session will demonstrate practical approaches to tackling
Specialist Mathematics exam questions, with a focus on
comparing the use of the TI-Nspire and Casio ClassPad
calculators. The presenter will compare and contrast how
each device can be used for different assessment items and
guide participants in evaluating the effectiveness of these
