Sue trained as a secondary mathematics teacher at Cambridge University. She taught in London comprehensive schools, and worked with colleagues on early uses of ICT in teaching mathematics, including David Tall's Graphic Calculus.
Sue moved to Kings College London to work on Graded Assessment in Mathematics, the precursor to the National curriculum. PGCE and Masters courses and subsequently on the Nuffield Advanced Mathematics project, precursor to the current Alevel 'Use of Mathematics'.
In 1997 she moved to the Open University to co-ordinate the Mathematics PGCE and the development of maths subject knowledge of Primary PGCE students. For three years, she was Director of NOF-funded ICT training in Bedfordshire and Hertfordshire, based at De Montfort University, before returning to the OU to work on Researching Mathematics Learning and courses to develop mathematics subject knowledge of non-specialist teachers. This programme resulted in 3 books in the Sage 'Developing Thinking in Mathematics' series.
In collaboration with Clare Lee, working with students, teachers, school leaders, and parents, she has developed the construct 'Mathematical Resilience' as a positive framework for working with schools and families on 'the maths problem'. In collaboration with The Progression Trust and Asdan, she has developed a programme for developing Coaches for Mathematical Resilience, so that mathematically anxious adults can support mathematics learners, from where they are now with their mathematics. Sue has also used her work to contribute to a development programme that aim at strengthening STEM capabilities and resilience in two districts in South Africa. The project blog can be found here.
Sue was Chair of the Association of Teachers of Mathematics between 2005-2009 and has previously held the post of joint-editor of Micromath, a journal of the Association of Teachers of Mathematics.
