This collection brings together classic, previously-published articles and new research to present the emerging field of ethnomathematics from a critical perspective, challenging particular ways in which Eurocentrism permeates mathematics education. The contributors identify several of the field's broad themes - reconsidering what counts as mathematical knowledge, considering interactions between culture and mathematical knowledge, and uncovering hidden and distorted histories of mathematical knowledge. The book offers a diversity of ethnomathematics perspectives that develop both theoretical and practical issues from various disciplines including mathematics, mathematics education, history, anthropology, cognitive psychology, feminist studies, and African studies written by authors from Brazil, England, Australia, Mozambique, Palestine, Belgium, and the United States.
