Career highlights
Associate Professor Wanty Widjaja is the Associate Head of School International and Engagement of the School of Education. Wanty's research focuses on understanding complexity of classroom practices and examining ways to support teacher professional learning and student mathematical reasoning. Two recent and notable Category 1 and 2 grant successes are Australian Research Council (ARC) Discovery Project Primary teachers adaptive expertise in interdisciplinary maths and science (2021-2024, $291,422) and Secondary Mathematics and Science initiative for out-of-field teachers funded by Victorian Department of Education and Training.
Prior to joining Deakin in 2012, Wanty has taught in Indonesia and Singapore. She has continued to strengthen research partnerships with researchers from the Netherlands, Singapore, Taiwan, Malaysia, and Indonesia on design-based research, mathematical modelling, Lesson Study, and STEM education.
Drawing on her research experience on mathematical reasoning project, Lesson Study and video-based methodology, Wanty was involved in delivering professional development sessions for numeracy coaches for networks of schools in the former Western Metropolitan Region in 2013 and at the Primary Mathematics and Science Specialists Program in 2015 and 2018.
