Robin H. Millar is Professor of Science Education at the University of York. He graduated in Natural Sciences at the University of Cambridge (Part 2 in Theoretical Physics) before completing a Ph.D. in Medical Physics at the University of Edinburgh. He then trained as a teacher, and taught physics and general science for eight years in secondary schools in the Edinburgh area before moving to York in 1982. He teaches on initial and in-service education programmes for science teachers, and supervises students on masters’ and Ph.D. programmes in education. His main research interests are in students’ concept learning in science, the role of practical work in science teaching and learning, scientific literacy, and the relationship between research and practice in education. He has directed several large research projects in science education, including Young People’s Images of Science and Procedural and Conceptual Knowledge in Science Education, both funded by the UK Economic and Social Research Council (ESRC). He was a member of the UK group in a European Union funded research project on Labwork in Science Education, which looked at how practical work is used in science teaching at upper secondary school level in several European countries. More recently, he co-ordinated a research network on Evidence-based Practice in Science Education. He has also played a leading role in several major science curriculum development projects, including Salters’ GCSE Science, Salters Horners Advanced Physics, and the innovative AS-level course Science for Public Understanding. He currently co-directs the 21^st Century Science project, a national pilot study of a more flexible science curriculum model for 15-16 year old students, with a central emphasis on scientific literacy. Robin Millar was President of the European Science Education Research Association (ESERA) from 1996-2000. He is a member of the Science Expert Group advising OECD and the Australian Council for Educational Research on the 2006 PISA (Programme for International Student Assessment) science survey.
