This book presents a report on a three-and-a-half year research project, ‘Techno-mathematical Literacies in the Workplace’, that was conducted by the authors between October 2003 and June 2007. This chapter introduces the key ideas and aims of the project and some of the main theoretical and practical approaches adopted. Chapters 2 to 5 of the book present the body of research findings from the different industry sectors that we studied: manufacturing (Chapters 2 and 3) and financial services (Chapters 4 and 5). Each chapter consists of ethnographic observations of companies, and accounts of the design and development of new learning materials undertaken with companies. Chapter 6 concludes the book by bringing together key findings and observations across all the industry sectors covered in the research, the challenges of researching the workplace and the implications for improving ‘techno-mathematical’ learning at work.
