Dr Colin Foster
I am a Reader in Mathematics Education in the Mathematics Education Centre at Loughborough University, England. 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 exploring the use of confidence assessment as a tool for formative assessment. 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 nearly 200 articles, 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 Mathematics Education Centre at Loughborough University. 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 on the Executive Committee of the British Society for Research into Learning Mathematics and I am a Convenor for the Mathematics Education Special Interest Group at the British Educational Research Association. I am also a Director of Shell Publications Ltd.
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 an 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 Network, 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. I was a member of the Department for Education Expert Group for the mathematics national curriculum and I devise questions 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 exploring the use of confidence assessment as a tool for formative assessment.
I am currently working on four major projects.
The first is an ESRCfunded project entitled Exploring sociallydistributed professional knowledge for coherent curriculum design. This is a collaboration with colleagues from Project IMPULS at Tokyo Gakugei University, and involves Keiichi Nishimura, Geoff Wake and Fay Baldry.
The second project is Investigating Mathematical Attainment and Progress, funded by the Nuffield Foundation, in which I am collaborating with Jeremy Hodgen, Margaret Brown, Robert Coe and Steve Higgins. This project aims to provide evidence to inform policy and practice directed at narrowing the achievement gap in mathematics.
The third project is the Mathematical Etudes Project, which is a study into the development of mathematical fluency in secondary mathematics students.
The fourth project is the Confidence Assessment Project, which is looking at how asking students to indicate how sure they are about the answers they give in lowstakes mathematics tests can contribute to formative assessment.
In addition, I am also involved in two smaller projects, one with Matthew Inglis, employing techniques from corpus linguistics, and one with Ian Jones, using comparative judgment to examine standards in Alevel mathematics examination papers.
I recently appeared as a guest on the Mr Barton Maths Podcast: click here to listen.
I supervise PhD students across a variety of topics within mathematics education.
