We organised them along with Melissa Rodd and Margaret Brown and spent a year touring the UK, starting in London, then heading to Manchester, Edinburgh, Cardiff, and Shef? eld, before returning to London for the ? nal seminar. These six seminars brought together a number of researchers and practitioners working in the areas of mathematics education and in edu-cation and identity to discuss how we can better understand patterns of participation in mathematics. This book is an edited collection mostly of the papers presented at those seminars, with additional contributions from other international scholars.
