Dr Colin Foster
I am a Reader in Mathematics Education in the Department of Mathematics Education at Loughborough University, England.
I am EditorinChief of the International Journal of Mathematical Education in Science and Technology and was President of the Mathematical Association 202223. My research interests in mathematics education focus on the learning and teaching of mathematics in ways that support students’ conceptual understanding. I am particularly interested in the design and use of rich tasks in the mathematics classroom, and in finding ways to enable students to develop the necessary fluency in mathematical processes to support them in solving mathematical problems. I am also interested in confidence assessment as a tool for formative assessment. I am CoDirector of the ESRC Centre for Early Mathematics Learning. For more details, please click on 'Research interests' above. The four aspects of my work highlighted below may be of interest to teachers and researchers.

Mathematical Etudes are creative, imaginative and thoughtprovoking ways to help learners of mathematics develop their fluency in important mathematical procedures. They are an alternative to traditional, tedious exercises. Click here to take a look. 
This website contains a free collection of over 40 starting points (beginnings) for mathematical activity. They could be used with learners aged around 11 upwards as a part of normal mathematics lessons or as something 'a little different'. Some prompts are provided to help learners find mathematics to work on and some brief teacher's notes are also offered, indicating possible mathematics that could emerge. Click here to take a look.

This popular series of three books of lesson ideas, published by Nelson Thornes, is now available free. The three volumes address Number and Algebra, Shape and Space, and Data Handling and ICT. Click here to take a look.

I have written over 300 articles, including both academic papers and articles for teacher professional journals, as well as 13 books. Many of these contain lesson plans and teaching resources. Click here and here to take a look.

Dr
Colin Foster I am a Reader in Mathematics Education in the Department of Mathematics Education at Loughborough University, UK. I am EditorinChief of the International Journal of Mathematical Education in Science and Technology and I am a member of the Editorial Board of Research in Mathematics Education. I am a Director of Shell Publications Ltd and I was President of the Mathematical Association 202223.
Previously, I was an Associate Professor and Director of Research in the School of Education at the University of Leicester, and before that I was a Senior Research Fellow and then Assistant Professor in the Centre for Research in Mathematics Education at the University of Nottingham. Before being an academic, 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 15 years. During 20052008, I coedited the journal Mathematics Teaching, published by the Association of Teachers of Mathematics.
Alongside my research, I direct the Loughborough University Mathematics Education Network, sometimes lecture mathematics to undergraduates and teach preservice teachers on the PGCE secondary mathematics course at Loughborough University, supervise masters and PhD students and lead professional development for mathematics teachers. I write regularly for the magazine Teach Secondary and for mathematics teacher professional journals, including Mathematics in School, published by the Mathematical Association, and Mathematics Teaching, published by the Association of Teachers of Mathematics. I was a member of the Department for Education Expert Group for the mathematics national curriculum and I am an examiner for Cambridge Assessment.
I am a Chartered Mathematics Teacher, a Fellow of the International Society for Design and Development in Education, a Senior Fellow of the Higher Education Academy and a member of the British Educational Research Association, the International Group for the Psychology of Mathematics Education, the National Council of Teachers of Mathematics and the Association of Mathematics Education Teachers.
Before mathematics education, I worked in chemistry. Click here for my thesis and a related paper.
If you are interested in studying for a PhD in an area relating to my research interests, then please email me with your ideas.

Research
My research interests in mathematics education focus on the learning and teaching of mathematics in ways that support students’ conceptual understanding. I am particularly interested in the design and use of rich tasks in the mathematics classroom, and in finding ways to enable students to develop the necessary fluency in mathematical processes to support them in solving mathematical problems. I am also interested in confidence assessment as a tool for formative assessment.
My main research focus is currently as a CoDirector of the Centre for Early Mathematics Learning, funded by the Economic and Social Research Council (ESRC), which is part of UK Research and Innovation. This ESRC Centre will transform understanding of children’s mathematics learning during the early years and design effective educational activities to improve skills and knowledge. Related to this, in my role as Director of the Loughborough University Mathematics Education Network, I am leading a designresearch project to construct the LUMEN Curriculum, a completely free, researchinformed, full set of mathematics curriculum resources for schools. This builds on a recent Economic and Social Research Council (ESRC) project Exploring sociallydistributed professional knowledge for coherent curriculum design, carried out in collaboration with Professor Geoff Wake, Dr Fay Baldry and Professor Keiichi Nishimura.
I am continuing to build on my research in the Mathematical Etudes Project, which is a study into the development of mathematical fluency, and also the Confidence Assessment Project, which is exploring how asking students to indicate how sure they are about the answers they give in lowstakes mathematics tests can contribute to formative assessment.
I have twice spoken about my research as a guest on the Mr Barton Maths Podcast: click here and here to listen.
I supervise PhD students across a variety of topics within mathematics education.
