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 from Singapore. Currently she is leading an internal research project which aims to understand professional noticing by expert primary school teachers in relation to their students’ mathematics and scientific reasoning. She has continued to strengthen research partnerships with researchers from the Netherlands, Singapore and Indonesia on design-based research and mathematical modelling.

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