Dr Colin Foster MA(Cantab), PhD, PGCE, CMathTeach, SFHEA
I am an Assistant Professor at the Centre for Research in Mathematics Education in the School of Education at the University of Nottingham. I am interested in the design of rich mathematical tasks and ways in which teachers can use and adapt them in the classroom to support conceptual understanding of mathematics.

Research My research interests in mathematics education focus on the learning and teaching of mathematical problem solving and the design of rich tasks and their use in the mathematics classroom. I am particularly interested in the development of mathematical fluency.
I am currently collaborating with Jeremy Hodgen, Margaret Brown, Robert Coe and Steve Higgins on the Investigating Mathematical Attainment and Progress project, funded by the Nuffield Foundation. This aims to provide evidence to inform policy and practice directed at narrowing the achievement gap in mathematics. I am also studying the development of mathematical fluency in secondary mathematics students in the Mathematical Etudes Project and working with Matthew Inglis on several corpus linguistic studies.
I teach preservice teachers on the University of Nottingham PGCE course and supervise masters and PhD students in mathematics education.

Website www.mathematicalbeginnings.com 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.
