In 1996 he co-authored, with Nerida Ellerton, a UNESCO book on mathematics education research. He is honorary life member of both the Mathematics Education Research Group of Australasia (MERGA) and the Mathematical Association of Victoria (MAV). Alan Bishop is Emeritus Professor at Monash University, Australia. He was Professor of Education at Monash University between 1992 and 2002 .He edited (1978-90) the international research journal, Educational Studies in Mathematics, published by Kluwer, and has been an Advisory Editor since 1990. He is Managing Editor of the book series Mathematics Education Library, also published by Kluwer (1980–present). He has authored or edited several influential books, reports, articles and chapters on mathematics education, and was Chief Editor of the first two International Handbooks of Mathematics Education (1996 and 2003) published by Kluwer (now Springer). Christine Keitel is Professor of Mathematics Education at the Freie University, Berlin, where she teaches prospective primary and secondary school teachers of mathematics. In the 1970s she worked as a research fellow at Max-Planck-Institute for Educational Research in Berlin on theoretical and practical approaches to curriculum development. In 1980, she became Director of a practice-oriented teacher education project at the Institute for Didactics of Mathematics in Bielefeld. She then moved to the Technical University of Berlin (TUB) and passed her Habilitation/venia legendi in the Mathematics Department of that University. In 1990 she obtained her professorship at Freie University. Her main research interests are mathematics as a social practice; philosophy and sociology of mathematics and the sciences; mathematics for all; mathematical literacy; mathematics education and technology; social justice and mathematics education: gender, ethnicity and class and the politics of schooling; history and current state of mathematics education around the world; comparative studies on mathematics classroom practice and learners’ perspectives; political and social dimensions of research on mathematics classroom practice, internationalisation and globalisation of scientific collaboration; difficulties faced by students and teachers in mathematics classrooms; mathematics education and values. In 1994 and in 1999–2001 she was guest professor in South Africa/Durban, and in Melbourne and Queensland in 2002 and 2004. In 1999 she was awarded an Honorary Doctorate in Sciences by the University of Southampton, and the A. v. Humboldt-Scholarship Award for Research and Capacity Building in South Africa. In 2009 she was awarded an Honorary Doctorate in Sciences by the University of Shumen, Bulgaria. Between 1999 and 2001 and also between 2007 and 2010 she was Vice-President of Freie University responsible for transformation of study orders into Bachelor and Master programs. Jeremy Kilpatrick is Regents Professor of Mathematics Education at the University of Georgia. He holds A.B. and M.A. degrees from the University of California, Berkeley, and M.S. and Ph.D. degrees from Stanford University. Before joining the Georgia faculty, he taught at Teachers College, Columbia University. He is a National Associate of the National Academy of Sciences and a Fellow of the American Educational Research Association, received a 2003 Lifetime Achievement Award from the National Council of Teachers of Mathematics, and received the 2007 Felix Klein Medal honoring lifetime achievement in mathematics education from the International Commission on Mathematical Instruction. Frederick Koon-Shing Leung is Professor in Mathematics Education within the Faculty of Education of the University of Hong Kong. Born and raised in Hong Kong, he obtained B.Sc., Cert. Ed. and M.Ed. qualifications from the University of Hong Kong, and Ph.D. from the University of London Institute of Education. His major research interests are in the comparison of mathematics education in different countries, and in the influence of culture on teaching and learning. He is principal investigator of a number of major research projects, including the Hong Kong component of the Trends in International Mathematics and Science Study (TIMSS), the TIMSS Video Study, and the Learner’s Perspective Study (LPS). He was a member of the Executive Committee of the International Commission on Mathematical Instruction (ICMI) and the Standing Committee of the International Association for the Evaluation of Academic Achievement (IEA). He was awarded a Senior Fulbright Scholarship in 2003, and is a honorary professor of Beijing Normal University, Southwest University, and Zhejiang Normal University in China.
