Scholars from the diverse strands of research have contributed their perspectives on mathematisation, a process that renders social, economical or political relationships increasingly formal. At the same time, mathematical skills lose their importance because a diversity of technological tools replace them; a process of demathematisation takes place. The authors discuss the concomitant educational issues from social, political or philosophical perspectives. Scholars and students interested in mathematics education and related disciplines will find this volume to contain a valuable collection.
