Queensland
Bruce Addison
After beginning work in the banking industry, I have now been a teacher for thirty-five years. Currently I am Deputy Principal (Academic) at Brisbane Girls Grammar School. My curriculum background is in both economics and history, having spent much of my career in the field of senior secondary school economics. I am a life member of the Queensland Economics Teachers Association.
I have taught at co-educational as well as boys’ and girls' schools, having both middle and senior management experience, specialising in curriculum and staff leadership. For a number of years, I co-ordinated and taught postgraduate subjects in both curriculum and leadership at the University of Queensland, also having had a variety of sessional academic experiences at both QUT and Griffith Universities. In 2017 I attended the course Leadership: An Evolving Vision at Harvard University’s Graduate School of Education. This learning was both provocative and engaging. These experiences have helped shape my understanding and practice of educational leadership significantly.
My doctoral research was undertaken at the University of Queensland in the field of educational leadership. I have published in this field as well as in academic care and educational change, specifically focussing on teacher professional growth.
Throughout my career I have contributed broadly to the quality assurance work of the Queensland Curriculum and Assessment Authority and its various antecedents. This experience has included appointments as both a District Panellist and Panel Chair, membership of various syllabus writing committees as well as membership of a range of assessment writing and review committees. This work has given me broad cross-sectoral experience particularly relating to both assessment development and quality assurance.
One of the core areas of my work revolves around teacher professional growth and practice. When not enmeshed in schools and education, my garden is my quiet place to tend, rest and restore.
Schools to me are the essential bedrock of our civil society. The teaching profession needs strong advocates, and this is why peak bodies such as ACEL are crucial.
