10 Ubi D’Ambrosio a professional mathematician and philosopher “recognized for bringing the significance of ethnomathematics as a viable research field to the attention of mathematics education” in 1985 From a book review in ZDM Mathematics Education (2008) 40:1033–1034 by H. Burkhardt of Ethnomathematics: Link between traditions and modernity. D’Ambrosio (2006). (A. Kepple, Trans.)

11 Ethno-mathema-tics ‘Ethno' refers to identifiable cultural groups, such as national-tribal societies, labor groups, children of a certain age bracket, professional classes, etc. and includes their ideologies, language, daily practices, and their specific ways of reasoning and inferring. 'Mathema' here means to explain, understand and manage reality specifically by ciphering, counting, measuring, classifying, ordering, inferring and modeling patterns arising in the environment. The suffix 'tics' means art or technique.

12 International Study Group on Ethnomathematics (ISGEm) Newsletter, Volume 11, Number 1, December Ethnomathematics is the study of mathematical techniques used by identifiable cultural groups such as indigenous societies, groups of workers, professional classes, and groups of children of a certain age group, etc in understanding, explaining, and managing problems and activities arising in their own environment.

13 An Example Professional basketball players estimate angles and distances Truck drivers estimate angles and distances Both are identifiable cultural groups that use mathematics in their daily work. They have their own language and specific ways of obtaining these estimates and ethnomathematicians study their techniques.

22 Time to Chat Give yourself 2-3 minute to skim bits of the article and 3-4 minutes to discuss as a group. Assign someone to report back 1 or 2 points from your discussion.

23 Why Ethnomathematics? Commitment to culturally responsive teaching Learning mathematical content from ethnically and culturally diverse origins increases teachers’ effectiveness with culturally and ethnically diverse students (Gay, 2000) Offering academic knowledge and skills “situated within the lived experiences and frames of reference of students” (Gay, 2000) leads to more personally meaningful experience and more readily and thoroughly learned mathematics. Showing math as a culturally rich subject
