## Lyndon Martin

**Vice-Provost Academic, Professor**

**D.Phil** - Oxford University, UK; **B.Sc (Hons)** - Loughborough University, UK; **Cert.Ed.** - Loughborough University, UK

## Biography

I am presently Professor and Dean of the Faculty of Education. Before coming to York in 2009 I held three previous academic appointments: Kingston University (UK); University of British Columbia; University of East Anglia (UK). I also worked as a Research Associate at Oxford University and as a high school teacher of mathematics.

## Scholarly Interests

My research is broadly situated in the field of mathematical thinking, learning, and teaching. More specifically I am interested in the notion of mathematical understanding - driven by the main question of what it might mean to understand a mathematical concept in different situations, and of how we might improve mathematics teaching to promote mathematical understanding.

Current and recent projects include: the potential for theoretical frameworks of understanding as pedagogical tools; the nature of collective understanding (especially as an improvisational process); workplace mathematical learning and understanding; students’ lived experiences of learning mathematics in schools; and teachers’ evolving understanding of mathematics embedded in social justice context problems.
