Alannah Kohnertz, a passionate secondary teacher in her third year at St Luke’s Catholic College, Marsden Park NSW has introduced innovative practices that have sparked her students’ love for science. When she began, science classes were held in demountables. With the move to permanent labs in 2023, Alannah designed engaging, inquiry-based programs that encouraged critical thinking and collaboration among students and staff.
She also led initiatives to inspire Year 8 girls to pursue STEM and, in her second year, taught Investigating Science for the first time, using diverse instructional strategies to promote student ownership of learning. Her approach led to outstanding 2024 HSC results—80% of students exceeded expectations, ranking second in learning gain across the Diocese of Parramatta, according to DeCourcy Analysis.
Recognising a gap in access, Alannah worked with Stage 3 teachers to bring primary students into secondary labs, giving them hands-on science experiences that built inquiry skills and a love for learning. Her work reflects a deep commitment to inclusive, high-quality science education.
What inspired you to become a teacher?
Growing up, I was fortunate to watch my mum work as a science teacher, and her dedication and enthusiasm made a lasting impression on me. From an early age, I developed a strong passion for science, particularly biology. Teaching allows me to combine my love for the subject with the joy of helping students experience those “lightbulb” moments when they discover something new. It’s incredibly fulfilling to be part of their learning journey and to inspire the same curiosity and excitement that first drew me to science.
Can you share a moment in your career where you really felt you made a difference?
There have been many rewarding experiences throughout my career. One that stands out is seeing the genuine excitement on the faces of primary school students when they step into the science lab for the first time and get to take part in hands-on experiments. Their enthusiasm is infectious and reminds me why I love teaching. At the other end of the spectrum, I’ve also found it incredibly meaningful to support senior students as they work towards their goals, whether that’s helping them grasp challenging content, boosting their confidence, or offering guidance on their post-school pathways. Knowing I’ve played a small role in shaping their future is fulfilling.
Is there a story from your time teaching that has in inspired you/had a deep impact on you? What stays with me are the students who’ve taken the time to thank me, especially those who’ve shared that I supported them through tough times. I remember one senior student in particular who told me I always seemed to know exactly what to say when things felt overwhelming. Moments like that remind me that teaching is about so much more than just content. I’ve also run into former students who’ve said they’re now studying science at university, and that our classes helped spark that passion. It’s incredibly rewarding to know you’ve had a lasting impact, both personally and academically.
How does your faith shape your teaching approach?
I aim to create an inclusive and supportive classroom where every student feels safe to ask questions, explore ideas, and be themselves. My Catholic faith plays a role in this. It encourages me to see the value in each person and to teach with compassion and care. I see science as a great way to spark curiosity and wonder about the world, and I want students to grow not just in knowledge, but also in confidence, respect, and empathy.
What’s the most rewarding part of teaching in a Catholic school?
Having spent 13 years as a student in the Catholic school system, I really value the strong sense of community that catholic schools foster. That sense of belonging and shared purpose goes far beyond the classroom, it’s felt in the way staff, students, and families come together to support one another and live out shared values. For me, the most rewarding part of teaching in a Catholic school is being part of that supportive environment, where faith, compassion, and community are at the heart of everything we do. It creates a space where meaningful relationships and shared experiences help students grow not just academically, but personally and spiritually as well.
What do you think is the most valuable role Catholic education plays in today’s society?
I think one of the most valuable roles Catholic education plays today is building a strong sense of community grounded in shared values. It creates a space where students feel they belong and are encouraged to care for others. With a focus on the dignity of each person and the goal of the common good, Catholic schools help students grow into people who are not only well-educated but also compassionate, socially aware, and committed to making a positive difference in the world.
