A28 USING EXPONENTIAL MODELLING
INVESTIGATION THROUGH DIVERSE
WORLDVIEWS
Subtheme: Pedagogy and curriculum
Peter Beissman, Bayside Christian College, Angel Wong,
St Andrew’s Christian College
(Year 9 to Year 12)
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.
Key takeaways:
1. Accessible Modelling: A low-entry, high-ceiling task
using CAS technology enables students at different level to
participate
A29 2024 VCAA MATHEMATICAL METHODS
EXAMS 1 AND 2 REVIEW
Subtheme: Pedagogy and curriculum
Allason McNamara, Trinity Grammar School, Cathy
Devlyn, Melbourne Grammar School
(Year 11 to Year 12)
Allason and Cathy will do a similar session to the 2025 MAV
Meet the Examiners Lecture for Mathematical Methods.
They will discuss common errors that students made on the
2024 examinations. Cathy will talk about Exam 1 and Allason
Exam 2. The statistics for each question will also be shown.
Key takeaways:
1. Teachers will be aware of the common mistakes students
make in Mathematical Methods examinations.
2. The session will help teachers to plan their 2026 classes
for effective student learning.
Remember:
Please bring the 2024 Mathematical Methods exams.
A30 2025 SPECIALIST MATHEMATICS - PEN
AND PAPER VERSUS CAS?
Subtheme: Pedagogy and curriculum
2. Mathematical Investigation: Modifiable for VCE Methods,
encouraging conjectures linking math to worldviews.
Peideng Nie, Austin Education
(Year 11 to Year 12)
3. Real-World Impact: Connects exponential models to
global issues, and comparing of worldviews, enhancing critical
thinking.
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
approaches in relation to the three outcomes of the VCE
Mathematics Study Design (2023–2027).
Remember:
A TI CAS calculator will be used for the presentation but a
CASIO can be used to follow along.
Key takeaways:
1. The attendees will exchange and share ideas and further
develop new networking opportunities.
2. The presenter will provide sample solutions to the
questions discussed.
3. Participants will discuss approaches to solving problems,
and take away ideas to inform resource development for their
own cohorts.
