Career highlights

Wanty has extensive experience in large-scale research projects with colleagues from Indonesia and the Netherlands, as well as a small scale research project. Her research focuses on understanding complexity of classroom practices and examining ways to support teacher professional learning and student mathematical reasoning. Currently she is leading a cross-national study to promote STEM interdisciplinary teaching in maths and science using real-world tasks involving Australian and Indonesian secondary schools. 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.

Wanty was the design research task force leader of the international project, ‘Pendidikan Matematika Realistik Indonesia’ (PMRI) as part of an international collaborative project funded by the Indonesian government and the Netherlands (Do-PMRI project) between 2008-2010.

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. She has been the managing editor for The Indonesian Journal of Mathematics Education (JIMs-B) published by the Indonesian Mathematical Society since 2011.
