With the ninth edition of the four-yearly review of mathematics education research in Australasia, the Mathematics Education Research Group of Australasia (MERGA) discusses the Australasian research in mathematics education in the four years from 2012-2015. This review aims to critically promote quality research and focus on the building of research capacity in Australasia.

Katie Makar is an Associate Professor in mathematics education at the University of Queensland. Her research aims to improve classroom practices in teaching mathematics through inquiry. She is known internationally for her work in statistical reasoning and informal statistical inference with children. 
Shelley Dole is Professor and Head of School of Education at the University of the Sunshine Coast. Her research interests include children's mathematics thinking and learning, inquiry pedagogy, mental computation, rational number curriculum in the middle and early years of schooling, teacher professional development.
Jana Visnovska is a Lecturer in mathematics education at the University of Queensland. Her research focuses on ways to effectively support mathematics teachers' professional development. To this end, she is interested in ambitious and equitable classroom instructional practices, and in the design of environments that support teachers' development of such practices. 
Merrilyn Goos is Professor and Head of the School of Education at The University of Queensland. In addition to her current research interest in numeracy across the curriculum, she fosters collaborations between mathematicians and mathematics educators to support interdisciplinary research and development in university mathematics teaching and pre-service teacher education.
Anne Bennison is nearing completion of her doctoral studies at The University of Queensland in which she used a sociocultural approach to identify ways to support teachers to embed numeracy across the curriculum. She was awarded an Australian Association for Research in Education Postgraduate Student Research Award in 2013.
Kym Fry is a PhD student at The University of Queensland who is completing her study into assessing learning in inquiry mathematics classrooms. Her involvement in a number of research projects provides her with experiences seeing research in action in mathematics classrooms all over south east Queensland.
