BiographyI am an Assistant Professor at the Centre for Research in Mathematics Education in the School of Education at the University of Nottingham. Previously, I taught mathematics in secondary schools for 12 years. My first degree and PhD are from Magdalene College, Cambridge, and I obtained my PGCE from the University of Cambridge Faculty of Education. I have been designing mathematical tasks and writing books and articles for mathematics teachers for over 10 years. During 2005-2008 I co-edited the journal Mathematics Teaching, published by the Association of Teachers of Mathematics.
Alongside my research, I teach pre-service teachers on the PGCE secondary mathematics course at the University of Nottingham, supervise masters and PhD students and lead professional development for teachers on teaching mathematics in investigative ways. I write regularly for the magazine Teach Secondary and for mathematics teacher professional journals and I am a member of the DfE Expert Group for the mathematics national curriculum. I also devise questions for the AS/A Level Thinking Skills (9694) examination, administered by University of Cambridge International Examinations.
I am a Chartered Mathematics Teacher, a Fellow of the International Society for Design and Development in Education and a member of the International Group for the Psychology of Mathematics Education, the National Council of Teachers of Mathematics and the Association of Mathematics Education Teachers.
